After supplying power to the module, observe the front panel for the following indications:
• PWR LED should remain ON. If this LED is not ON, all other LED’s will also likely be
OFF. Check the PSI 90DB, 9IFC or user-provided power supply to ensure the proper
voltage (18-36 VDC) is being provided. Also verify that the power pins in the module
interface cable are wired as described in this manual, Appendix A.
• COL LED should remain OFF.
• TX LED should remain OFF. Note that any activity of the TX LED during the power-up
sequence is an indication that the RARP/BOOTP protocol is enabled. This will typically
occur following the initial BSY LED cycle and continue until an appropriate RARP reply is
received.
• LNK LED should remain ON. This LED indicates proper connection to an Ethernet hub
or switch. If this LED is OFF, verify that the module is properly connected to the
communications hub or switch. Verify proper power is applied to the hub. Also try
connecting the module cable to a different port of the hub. Note that most hubs have
similar link LED’s to indicate proper connection to the hub itself. If present, verify that the
hub link LED for the scanner and the host computer are both active. If the hub is
functioning correctly, verify that the communications pins in the module interface cable
are wired as described in this manual.
• CAL LED should remain OFF.
• PRG LED should remain OFF.
• BSY LED should blink 8-16 times, and then remain on for about 5 seconds. After that it
will blink at about a 100 Hz rate, which will cause the LED to appear to be on, but
dimmer than the other LEDs that are ON.
