This is applicable to the lithium battery packs intended for use with the CNI2. Specific requirements are applicable to Class-9 shippers: Product handlers must be tested and certified.
CNI2 Operating and Installation Guide CNI2 OVERVIEW The Honeywell CNI2 is a pulse accumulator (data logger) and serial data communications product with an integral cellular radio transceiver. Pulse signal inputs (dry contact) and alarm inputs can be supplied from an external electronic corrector or other measurement device. An index base option with both a mechanical index display and pulse switch output is available.
WALL MOUNTING Where a flat wall surface is available, such as on the side of a building or shed, stainless steel “hangers” can be utilized. Illustrated below is the rear view of a CNI2, along with associated mounting dimensions. Wall Mounting Tabs and Dimensions...

CNI2 Operating and Installation Guide VERTICAL PIPE MOUNTING Another mounting option available for the CNI2 is the pipe-mount. This adaptor will accept a 2 ⅜” (2.375”) diameter galvanized pipe, and is secured in place with a pair of Allen-head set- screws.
CNI2 Operating and Installation Guide ENCLOSURE SEALING Sealing of the enclosure is readily accomplished using either a conventional lock through the larger hole or a security wire seal through the smaller hole. Enclosure Sealing Options INTERNAL BATTERY POWER OPTIONS Several battery configurations are available to best serve the particular applications. Shown below is the dual-cell lithium power pack.
CNI2 Operating and Installation Guide A larger quad-cell lithium pack is also available for double the capacity of the dual cell type. Refer to the specifications section at the end of this manual for a comprehensive listing of battery pack options their part numbers.
Disposable Alkaline Battery Pack To avoid loss of system power to the CNI2 board during battery changes, it is recommended that the fresh batteries be connected to the available J1 or J2 connector before removal of the old battery pack.
Specific details of each board or option are described in more detail later. CNI2 Board Illustrated below is the CNI2 board with the cellular radio in the center, and various connectors around the perimeter. This represents the most common model that is supplied with no accessory boards and no index base.
Serial Port Multiplexer Board One of the accessory board options available is the serial port multiplexer. This enables the CNI2 serial data port to access two external devices (electronic correctors for example). Two terminal blocks provide the connection point for serial data cable.
CNI2 Operating and Installation Guide RS-485 Serial Data Converter Another accessory option available is the RS-485 conversion board. RS-485 is somewhat similar to the RS-232 standard in that it is a wired transmission line for serial data exchange. The RS-485 standard offers several advantages over RS-232 in terms of cable length distance, noise immunity, multi-node drops, etc.
RS-232 data link, and a pressure transducer that requires an RS- 485 connection. Take note however that serial data exchange can take place only on a channel at a given time. CNI2 Board with RS-485 Board and Multiplexer Board...
The simple block diagrams below provide an overview of serial data connection possibilities for the CNI2. For the sake of convenience, end devices are shown here as being a ‘Mini-Max’ corrector and a ‘Pressure Transducer’. The Mini-Max has an RS-232 port and the Pressure Transducer has an RS-485 port.
TB4. In the unlikely event that one of the two reed switches should fail, the redundant input channel will continue to register accurate counts. The illustration below shows the CNI2 with the rotary magnet and dual reed switches. Index Base with Magnetic Switches For the sake of clarity this illustration does not show the routing of wires from the sensor switches.
CNI2 Operating and Installation Guide Another option is the Uncorrected Pulse Output board, as seen below. This provides an additional dry-signal pulse output that allows for connection to an external pulse counting instrument. Pulse Output Board For the sake of clarity this illustration does not show the routing of wires from the sensor switches.
CNI2 Operating and Installation Guide A small Allen wrench tool is included with the index. Loosen the set screws on the top and bottom miter gears and swap the gear that engages. Shift the gear set upwards for meters with CW rotation and down for meters with CCW rotation.
CNI2 Operating and Installation Guide OPTIONAL REMOTE PULSE TRANSMITTER Some applications may not be suitable for a direct mount index on the CNI2 enclosure, due to available space or other reasons. Where this is the case, Honeywell also offers a remote pulse transmitter with mechanical index display.
CNI2 Operating and Installation Guide ANTENNA OPTIONS For the majority of site installations the most convenient and cost effect choice are CNI2’s with the internal cellular antenna as seen in the illustration below. This is a five inch length rectangular shaped circuit board (light blue color) that is mounted directly to the left inside wall of the enclosure.
CNI2 Operating and Installation Guide Where cellular signal reception is problematic, due to either terrain or proximity to cellular towers, it may be necessary to utilize an external antenna instead. This option is available in the form of a bulkhead N-Fitting (jack or female) mount as seen in the illustration. An external antenna can then be elevated as required and directionally pointed to the nearest cell tower.
J9 connector. This enables a field technician to swipe a hand-held magnet wand (part no. 20- 7286) near bottom left side with in order to initiate a call. In cases where the CNI2 enclosure is sealed with a lock or wire seal, this form of call trigger is very convenient.
CNI2 Operating and Installation Guide ELECTRICAL ASSEMBLIES CIRCUIT BOARD CONNECTORS & JUMPERS This chapter identifies the locations of important components, connection points, and jumpers on the CNI2 and accessory boards. CNI2 Circuit Board Layout...
Power Connectors J1 & J2 These connectors are intended for connection to power sources. Both connectors are identical in function, and allow for the hot-swap of batteries without the loss of power to the CNI2 board. J1 and J2 Power Connectors...
Terminal Block TB4 Terminal block TB4 is the connection point for pulse-counting or alarm-sensing inputs. If an index base is provided with the CNI2 then this connector will be prewired at the factory. JP3 & JP6 Jumper Settings Factory default settings for JP3 and JP6 are illustrated below. Manipulation of these jumpers allows for special operating modes and test functions.

(or transistor) with no drive voltage. It can also be defined as a “Special Purpose Output” which allows the CNI2 to use this line to control some internal function. This is described in more detail later in this document under the...
The RS-232 multiplexer is shown below. The connector J3 is pre-wired at the factory to the CNI2 board. When the RS-485 board is not included with the assembly then both serial ports are available for connection to external devices. An example might be two ECAT electronic correctors at a field site.
RXD line and DTR input line. The multiplexer board is able to detect serial data flow on the DTR line, even when in low power mode. This then enables the CNI2 board to wake from low power mode, drive the multiplexer board, and subsequently receive serial stream data.
If you are using half duplex operation you must select the “RS-485 Half Duplex” setting on the Serial Port Settings configuration screen. Honeywell has a document available that further details the RS-485 theory of operation and how it applies to this particular board. A Product Support Specialist can provide a copy of this document in PDF format upon request.
This option provides a single Form-C dry contact switch output for connection to other devices outside of the CNI2. Counts are proportional to those recorded by the other sensor switches that wire into the CNI2. This board mounts onto the small metal plate in proximity to the rotating magnet head as seen earlier.
CNI2 Operating and Installation Guide SIGNAL INPUTS & OUTPUTS There are a total of six digital signals on the CNI2 board that can be used as alarms, status inputs, pulse-counting inputs or control outputs. A later portion of this chapter provides a technical discussion about how each input is processed.
Or you can just momentarily short the J9 pins with a screwdriver or coin. This switch will cause the CNI2 to immediately call in to the central computer and report a “Call” or “Mag. Switch’ alarm.
(“repeater”). This allows other external equipment to have access to the same pulse or alarm information that is being processed by the CNI2. WARNING An output has strict limitations with respect to voltage and current. See the specifications section to avoid damage to the CNI2 board.
CNI2 Operating and Installation Guide POWER SUPPLY OPTIONS Illustrated below is a portion of the CNI2 board. TB1 is prewired at the factory to a high density capacitor element to support peak load demands when operating the cellular radio. J1 and J2 are the power connectors for the CNI2.
Polarity of the terminal block connection will be apparent from the opposite end wire colors in that Red is positive and Black is negative. In the event that a reverse connection is made by accident, no harm will be caused to the electronics aside from the fact that the CNI2 will not power as expected.
This allows the central computer to communicate directly with a device connected to the CNI2’s RS-232 serial port. Most applications for the CNI2 being used as a cellular modem will be with a Mercury corrector instrument. Other configurations are certainly possible as well, to support 3rd party instruments such as transducers, odorizers, etc.
Typical SIM Card If your CNI2 is equipped with a CDMA radio, then a SIM card is not required. A SIM card should not be installed into a CDMA configured CNI2. WARNING - Explosion Hazard Do not install or remove the SIM card while the circuit is live unless the area is known to be non- hazardous.
The otch on corner of SIM card faces away from the socket as illustrated above. WARNING: Never install or remove a SIM card when the CNI2 has power applied. There is some risk that the SIM card could be damaged if plugged / unplugged with power present.
CNI2 Operating and Installation Guide PROGRAMMING INFORMATION Each CNI2 must be programmed with information that relates to the cellular network, the type of data collection system that will be contacted, the type of inputs to process, etc. This is done ®...
CNI2 Operating and Installation Guide ® STARTING THE MP32 CONFIGURATION PROGRAM ® ® When the MP32 program is started a login screen appears. If the “DC-2009 ” data collection system is also running on this system then you will need to enter an authorized user name and ®...
CNI2 Operating and Installation Guide CONFIGURING THE PROGRAMMING PORT ® MP32 needs to know which COM port to use with the programming cable. Select the “Communications Configuration” button on the device selection screen. When the USB programming cable is first plugged in, the system should detect it and load the necessary driver software.
CNI2 Operating and Installation Guide STARTING THE CNI2 PROGRAMMING APPLICATION When the device selection screen reappears select the CNI2 button. The following screen will appear. Some fields are filled in for demonstration purposes and may be different than those you will enter.
‘A, B, C, D, E, or F’. Typically if you do not specify the ID number prior to shipment then the CNI2 is shipped with an RUID that is the last six digits of the serial number located on the front label.
Allow Connection Requests This setting allows the CNI2 to act as an Internet “server”, allowing it to be contacted via the Internet. When this box is checked the Server Mode configuration screen is used to define specific server features.
The data collection system (DC-2009 or MV90 ) must also be configured with the same interval size; otherwise the calls from the CNI2 will be rejected. Although the CNI2 can accept ® ® up to six channels of pulse information, DC-2009 or MV90 can only accept four.
CNI2 Operating and Installation Guide INPUT / OUTPUT CONFIGURATION The CNI2 has six (6) digital lines that can serve as alarm sensing or pulse-counting inputs, or as outputs. Four of the lines are available on four 2-pin MTA connectors J7, J9, J11 and J12, as shown earlier.
CNI2 Operating and Installation Guide Any description can be changed in the data collection system. For instance if Line#10 is used for something other than the TAMPER switch it will still be reported to the data collection system as a TAMPER alarm. But you can change the alarm description at the central office to something like “Pump Failure”...
CNI2 into a low-power conservation mode until the alarm event is over. During this time some features may not be available. For instance if the CNI2 is configured to respond to SMS pages, which requires that the radio be powered up and running all the time, this mode will be temporarily suspended and the radio will be powered down until the primary power has been restored.
The “Scaling Factor” is not currently supported. The CNI2 has the capacity to save a total of 30,000 pulse-counting records before it starts to overwrite the oldest records. These are divided equally between all active pulse-counting channels. If only one channel is used for pulse-counting then all 30,000 records will be used for that channel.
Page 69
) must know how many pulse-counting channels are activated. The minimum is 1 and the maximum is 4. When the data collection system receives the pulse records from the CNI2 it expects them to be in a specific order starting with the 1 input and ending with the last.
When a line is programmed as an alarm or pulse-counting input its state can be replicated on any one of the output lines, within the frequency limits of the CNI2. This allows other pulse- counting or alarm-sensing equipment to have access to the same information. For instance the CNI2 may be counting pulses and there may be another piece of equipment located nearby that needs to count these pulses too.
CNI2 Operating and Installation Guide “Special Purpose” Output The CNI2 will use a “special purpose” output to control some operation within the unit assembly, such as turning a power supply on or off. At this time the “Special Purpose” output only applies to Line-12, which is the J7 connector.
Options Screen Applications Selection The CNI2 has several modes of operation. It can serve as a data logger for pulse-counting and alarm sensing applications, a transparent modem to allow the host system to communicate with an external piece of equipment, or as a short-message-service (SMS) modem.
When you use your personal computer to access a website your PC is the client and the website is the server. A client cannot be contacted directly via the Internet. In many cases the CNI2 acts as a client only. However the CNI2 can be “paged”. The page then causes the CNI2 to call back immediately to the central office.
SMTP server. The SMS Modem is a special configuration of a CNI2. Its sole purpose is to allow the central computer to send mobile-to-mobile SMS messages via the cellular network without interfering with existing Internet connections or requiring an email server connection.
Serial Port Configuration screen), then the “Route To” port will be selected and the CNI2 will return the following response: <cr><lf> INVALID PORT NUMBER OR PORT IS NOT ENABLED<cr><lf> If the +-+PA command is not received within the specified time frame then the CNI2 will select a port based on the “Route To” setting.
Even if the “immediate call” box is checked the data collection system (DC-2009 or MV90 has the ability to override it. The CNI2 will record the time of the day that the alarm event occurred and this time will be reported to the central office. Queue Size The CNI2 can count electrical pulses from up to siz sources although the data collection system ®...
Rather the CNI2 briefly inspects (“samples”) the condition of the lines one or more times each second. You can configure the CNI2 to take as few as one sample per second or as many as 50 samples per second. The 12 possible input/output lines are divided into two groups, each with its own sampling rate.
Each serial port must be assigned a unique Port Select ID number. The format follows that of the Primary RUID discussed earlier. Serial Port-1 is the physical port TB2 on the CNI2 board and is automatically set to the Primary RUID. Its Port Select ID is grayed out and cannot be changed.
Hardware handshaking uses additional signals on the hardware interface to stop and start the flow of data from the serial device. On the CNI2’s terminal block is an output signal called DSR. This signal would normally be connected to the “CTS” (clear-to-send) input line on the serial device.
Xon/Xoff handshaking (also called “software handshaking”) uses two ASCII characters to stop and start the flow. The CNI2 will send an “Xoff” (19 decimal or 13 hex) to the serial device to stop the transmission, and an “Xon” (17 decimal or 11 hex) to resume transmission. Once an Xoff character is sent the serial device should halt its transmission.
The CNI2 can also place a call on its own in response to an alarm condition or some other event. In these situations the CNI2 would not normally send a “CONNECT” message to the serial device.
Some serial devices may indicate a desire to place a call by simply activating a control line. On the CNI2’s TB2 terminal block is an input line called DTR. If the DTR input line on the communications terminal block goes positive, the CNI2 will wait 10 seconds for an “ATD” (dial) or “ATA”...
Some serial devices may indicate a desire to terminate a call by simply deactivating a control line. On the CNI2’s TB2 terminal block is an input line called DTR. If the DTR input line on the communications terminal block is positive when the call starts, and then goes negative while the call is in progress, the CNI2 will terminate the call.
Thus the number of conversations is limited by the overall interference and noise in the room. A cellular account must be activated with a cellular service provider prior to placing a CNI2 into service. The service provider may ask the device type, which must be specified as the “CNI2 / CDMA24”.
The final consideration is the direction of the calls. If the CNI2 is to originate calls, then the service must support “mobile-originate” service. If the unit is to receive calls, then “mobile- terminate”...
CNI2 Operating and Installation Guide be forwarded at no additional charge. The preferred roaming list says that it is acceptable to connect with these carriers. However at some point your service provider may install new equipment in these areas and the contract with the partner may be terminated. In this new situation roaming fees will be added to each call if the radio is allowed to connect to the other carriers.
64-bit data encryption standard (DES64). If this exchange fails, the connection is terminated by both sides. When the CNI2 calls in it assigns itself what is known as a “source port” number. To further enhance security the CNI2 can be assigned only one or a specific range of source port numbers that the firewall will allow through.
Excessive retries may cause your maximum plan limit to be exceeded. If you notice excessive retries, or if the connection between the CNI2 and the central computer terminates early or often, this may be the cause.
Typically the smallest available package will be 1 megabyte (1 Mb) per month. The amount of data that the CNI2 will produce depends upon what sort of data is requested from it. The amount of information exchanged on each call may range from several hundred bytes to 10’s of thousands of bytes.

Excessive retries may cause your maximum plan limit to be exceeded. If you notice excessive retries, or if the connection between the CNI2 and the central computer terminates early or often, this may be the cause.
Due to the availability of iDEN radios support for iDEN service will not be offered after 2010 and may be discontinued earlier. HSPAService HSPA (High Speed Packet Access) is not yet supported by the CNI2. If this selection is made the CNI2 will display an error code of “15” until another selection is made.
Call Retry Strategy If the CNI2 attempts a call and the call is unsuccessful for any reason, it can try the call again at a later time. It can also be told to retry the call to a different computer or not retry the call at all.
Call Retry Interval defines the number of hours between each additional attempt, up to 255 maximum. There is no limit to the number of times the CNI2 will attempt a call at this rate. Once a call is successful the retry strategy is cancelled.
CNI2 acts as a client only. However the CNI2 can act as a server and accept connection requests from the outside world. It can do this on a full-time basis or at specific times during specific days of the week.
PROGRAMMING THE CNI2 Loading a Configuration with the Programming Cable IMPORTANT NOTE Programming the configuration into a CNI2 automatically resets the unit and clears all accumulated data. 1) Make sure the proper COM port is selected (see the beginning of this chapter).

5. When the OK button is selected the firmware information is saved in DC-2009’s database. This new firmware will be loaded into each CNI2 the next time it calls in. If for any reason the firmware update cannot be completed due to a network problem or a data error the old firmware will remain in effect until the new one can be transmitted.
CNI2 Operating and Installation Guide LED STATUS INDICATORS CALL PROGRESS AND STATUS Here is a typical sequence from the time the CNI2 is powered up to the time it completes its first call. The green LED is mostly used to indicate the status of the radio and the network whereas LED indicates the progress of the call.
LEDs will be reactivated for another 15 minutes. ERROR CODES The two LEDs on the CNI2 board are used to indicate call progress and call status. They are also used to display error codes. In the event of an error the LEDs will be flashed in a pattern that represents a 2-digit number.
The radio rejected the PIN number that is sometimes required for GSM SIM cards. The PIN number that was programmed into the CNI2 may not be needed or may be incorrect. If a PIN number is not required then it should be left blank.
CNI2 Operating and Installation Guide CODE DESCRIPTION The CNI2 cannot make a connection in CSD mode. This could be caused if the service provider does not support CSD connections or if the modem that is being called is not connecting.
Unexpected command from the data collection system. This might indicate a problem with the way the CNI2 is setup in the data collection system. Not used Not used Not used Unexpected response from the data collection system.
Then the LEDs will rapidly flash in an alternating pattern for anywhere between 10 – 30 seconds as the CNI2 reprograms itself. At the end of the operation the CNI2 will return to “sleep” mode and both LEDs will turn off.
Rather the CNI2 briefly inspects (“samples”) the condition of the lines one or more times each second. You can configure the CNI2 to take as few as one sample per second or as many as 50 samples per second. The 12 lines are divided into two groups, each with its own sampling rate.
“bounce” (open and close a few times), then finally settle in the closed position. This “bouncing” may be falsely interpreted as several events rather than just one. If the CNI2 is counting pulses from this switch it might interpret the bounce as two or three pulses rather than just one.
In the illustration alarm sensing or pulse counting is performed on the “INPUT-1” connection only. “INPUT-2” is used for fault detection. The switches should never be open or closed at the same time. If so the CNI2 will report an alarm condition. The next figure shows how a KYZ fault is detected.
The output line can be configured to replicate (follow) any of the input lines. This allows other pulse-counting or alarm-sensing equipment to have access to the same signals. For instance the CNI2 may be counting pulses on Line-2 and another piece of equipment located nearby may need to count these pulses too.
If the CNI2 will respond to AT modem commands in ALL modes of operation. If you have a serial device attached to the CNI2’s serial port it is likely that the device is expecting to communicate with an AT-compatible modem. The acronym “AT” means “attention”.
CARRIER”. If a connection does not exist then the normal response will be “OK”. ATA (answer) Command ATA: This instructs the CNI2 to answer an incoming call and establish a connection with the central computer. The normal response is a “CONNECT” message if a connection is established or “NO CARRIER”...
CNI2 Operating and Installation Guide NOTE If the CNI2 detects a decimal point (.) or a forward slash (/) in the dial string it will assume this is an IP address and Port #, and not a standard phone number.
In low-power sleep mode the CNI2 shuts down its serial port components in order to conserve power. However the CNI2 can still detect activity on the received data line (RXD) or the DTR line. A jumper on JP3 selects which line to respond to. To detect incoming AT commands the jumper should be set to the position shown here.
An Internet address and port number must be assigned to the SIP server, and these numbers must be programmed into each CNI2. Your computer systems’ administrator usually assigns the address and port number.
Select “SIP Server” for the port type. The port number will be filled in automatically, and must match the port number that was programmed into the CNI2. The default is 50466. If a different port number is being used then hold down the CTRL key on the keyboard, point to the Port Number box and double click on the port number box.
On the next screen select the “Analog Modem Ports” tab. Some cellular providers that support CSD calls do not support bit rates below 9600 bps, and the GSM version of the CNI2 does not support anything below 4800 bps. Therefore you will need at least one 9600 bps MODSMOD modem card in the Mercury MODSMOD chassis.
When the CNI2’s are in service you may want them to call in at regular intervals, say once an hour or once a day. You can define a call schedule for one CNI2, or a group of them by selecting “Call Configuration” from the Applications Launcher.
CNI2 will call in at regular 8-hour intervals starting at 14:00:00. This is a Periodic schedule. The CNI2 must make at least one call into the system in order to obtain the first call schedule. Thereafter each time the unit calls in DC-2009 will instruct the CNI2 to call again in 8 hours.
CNI2 Operating and Installation Guide DEFINING THE CNI2 – MANUAL MODE Now that you’ve defined how DC-2009 will communicate with a CNI2 you must define the CNI2 itself. Information in DC-2009 must correlate with the configuration of the CNI2. The number of data (pulse) inputs and the pulse-counting interval sizes must match exactly.
CNI2 Operating and Installation Guide The next screen will appear. It is not necessary to select a device that’s already been defined, simply select the ADD icon Remote Unit Selection Screen On the next screen select “Mercury Types” and OK.
For devices that will be communicating over the Internet check the “IP Enabled” box. For CSD devices leave this unchecked. Enter the New Remote unit ID (RUID) that was assigned and programmed into the CNI2 using MP32. Select “SIP” as the product type. Select the Call Profile that is desired.
Remote Unit Configuration General Information Screen With each call DC-2009 will ask the CNI2 for any data records that were accumulated since the last time it called in. This is referred to as a Send Latest operation and is the preferred method.
CNI2. As mentioned earlier, a CNI2 can use its inputs for either pulse-counting or alarm sensing. If a combination is used then DC-2009 must be told how many channels are being used for pulse- counting.
Select the Input Definition tab. Here you can match the time interval to that which was programmed into the CNI2. This will apply to all pulse-counting channels. You can also change the description of each channel and select which type of data to save. Contact a Product...
Call Information Screen The Dial Out phone number is what DC-2009 will use to call the CNI2. This might be used for a direct CSD call (“mobile-terminate”) or it may be used to “page” the unit, which will cause the unit to call back to the system.
This screen allows you to configure how alarms are reported to DC-2009 by the CNI2 and by DC-2009 to you. It also allows you to change the verbal description of each alarm. For instance the generic “Customer Alarm-2”...
But if you set the Nuisance Limit to 3 then DC-2009 will instruct the CNI2 to stop calling in after the third report of the same alarm. Later, when the CNI2 calls in at its regularly-scheduled time (12 hours later), the Nuisance Limit will be reset and the unit will again be allowed to report the alarm up to 3 times until the next scheduled call.
If pulse data is not collected often enough there is a chance that the oldest data may be lost due to insufficient memory. This memory is referred to as the “queue” and the CNI2 will call in to report a “Queue Full” alarm when a certain percentage of the queue contains new records.
Low Battery Alarm This alarm indicates that the battery pack in the CNI2 needs to be replaced as soon as possible. The voltage level at which the alarm will occur is programmed using MP32. The battery should be changed as soon as possible to continue uninterrupted service.
If you look at the General Information tab on the Remote Unit Configuration screen you will see a checkbox called “Active”. As long as this box is checked any new CNI2 that calls in for the very first time will be automatically added to the system under the RUID number that was programmed into the unit.
In packet (Internet) mode, the CNI2 also sends additional information about cellular status, battery voltage, error codes, etc. In DC-2009 you can view this information from the Call Information screen. Select the View CNI2 Cellular Parameters button on the right-hand side of the screen.
CNI2 Operating and Installation Guide The following information screen will appear. Cellular and Hardware Status Screen The Error Code Stack is a list of the most recent 30 errors that were detected and displayed on the LEDs. The most recent code appears first. Besides pointing out hardware problems certain other codes might explain why calls are failing and have to be retried.
Call Diagnostic Dump. Starting the Call Diagnostic Dump Utility When DC-2009 processes the CNI2’s information it creates a file called a “raw file”. This is usually stored in the Data Processing folder and is usually in a sub folder called “Output”. Each file has an extension of “.raw”.
The screen is formatted to show the data in both hexadecimal and ASCII format. Most of the information on the ASCII side of the screen is readable and contains information about the CNI2’s power condition and cellular status. This portion of the message is highlighted in the next figure.
CNI2 Operating and Installation Guide Here is how the information is formatted in the order it appears, including the comma (,) that separates each item: Parameter Item Example Internal logic supply voltage (volts) +3.23, Loaded battery voltage (volts) +1.78, Radio power voltage (volts) +3.42,...

CNI2 Operating and Installation Guide The entire string of power, cellular and error status ends with a 0 (null). This portion of the raw file could be processed as a comma-delimited file by a spreadsheet program. But beware that the length of the data preceding this information is variable, so this information block may not...

This includes both field wiring connections and battery pack replacement. If there are any operational problems directly related to the electronics of the CNI2, then it is often times more convenient to swap the unit out with a spare and then later make a...
CNI2 Operating and Installation Guide ESD HANDLING PRECAUTIONS Any electronics device contains components sensitive to ESD (electrostatic discharge). For example people experience up to 35kV ESD, typically while walking on a carpet in low humidity environments. In the same manner many electronic components can be damaged by less than 1000 volts of ESD.
