Chapter 2. Setting up the scanner This chapter provides instructions for installing and testing the 4685-L0D scanner. Installing the scanner ....... . .
Decide how you want to mount the scanner: Free-standing Fixed Before connecting the 4685-L0D scanner to the POS terminal, make sure that the POS terminal is turned off. Connect one end of the POS interface cable to the connector at the base of the scanner.
Installing the scanner stand The scanner stand has non-skid rubber feet, and is weighted for stability. It can be placed on a countertop with no additional installation, or it can be permanently mounted on the countertop. Free-standing: No additional installation is required. Fixed installation: Mount the stand to the countertop, using the stand mounting clip.

Chapter 3. Configuration of the 4685-L0D Scanner This chapter describes the features that can be configured and tells how to con- figure them and print configuration information for the 4685-L0D scanner. Configurable features ....... . .
If it is not, configure is at this stage. The RS-485 model and the USB model of the 4685-L0D scanner are configured by sending commands from the POS terminal. The RS-232 model is configured by reading programming bar codes.
The decoding algorithms for the 4685-L0D scanner can handle many of the errors com- monly caused by poor printing. If you need to, you can scan each bar code two or three times.
Sleep mode control To maximize the lifetime of the laser and the motor, the 4685-L0D scanner goes into sleep mode after the scanner is left inactive for a specified period of time. You can specify that time; the only requirement is that the timeout for the motor has to be longer than for the laser.
To change the settings on your scanner, use the rear scan line to scan the Switch Label; then scan the label for the rear laser mode you want, and scan the Switch Label again. The scanner resets and invokes the new mode of operation. This setting is saved. Chapter 3. Configuration of the 4685-L0D Scanner...

Software-flow operating mode In the software-flow operating mode, the conditions are as follows: On receiving a DTR signal, the scanner establishes a connection with a POS terminal, and then enters the ready state. The scanner decodes the labels immediately after power-on. The scanner buffers one additional label, if desired.

Intercharacter-delay operating mode The intercharacter delay operating mode provides a means of communication control by delaying the transmission of label data. The scanner delays the trans- mission of each succeeding character by a fixed, configurable amount. For details of the intercharacter delay operating mode, see Figure 4-4, Figure 4-5, and Figure 4-6.

Scanning with the 4685-L0D scanner With two scan windows, the 4685-L0D scanner can be easily adapted to either fixed/portable or targeted handheld scanning. The front scan window, with its mul- tiple scan pattern, is used for most retail items. The rear scan window emits a single targeted scan pattern for handheld scanning of bar codes on hard-to-read or bulky items, or to read an individual bar code among many bar codes.
The optimal scanning distance is at the center of the scan volume, or about 11 cm (4.5 inches) from the window. Figure 5-3 shows the motion of an item swept past the front scan window. Front scan window Bar code Figure 5-3. Sweep scanning IBM 4685-L0D Scanner: Setup, Operation, and Service Guide...
Figure 5-4. Presentation scanning Portable scanning To use the 4685-L0D scanner as a portable scanner, remove it from the stand, but do not press the trigger switch. Sweep the scanner over the bar code, using the front scan window as in Figure 5-5.
Grasp the scanner in the palm of the hand, with the thumb on or near the trigger switch. Thumb on trigger switch Figure 5-6. Using the 4685-L0D scanner as a targeted handheld scanner (1) Lift the scanner from the stand, and position it over the product to be scanned. Rear scan window Figure 5-7.
