APPENDIX B - EXTERNAL POWER SUPPLY

REQUIREMENTS

The MODEL 2500 can support both 12V and 5V LASERS (and CCD scanners).

The power source for the "LASER" connector on the front panel of the reader is

determined by a jumper located inside the enclosure.

When the jumper is set to the 12V or EXTERNAL position, 12V power is taken

directly from the external power supply. In this configuration an external 12V

regulated power supply MUST be connected to the reader.

When the jumper is set to the 5V or INTERNAL position, 5V power is supplied to

the laser interface.

The following table lists various configuration requirements:

INPUT POWER JUMPER

DEVICE REQUIREMENT POSITION

LASER 12V EXTERNAL

LASER 5V INTERNAL

C C D 5V INTERNAL

NOTE: The reader is shipped from the factory with the jumper set to

the INTERNAL position. This will supply 5V to the laser.
