4.3.1 Units are on the Bench

The following flowchart should help focus in on the fault.

Assuming you have a pair of boards on the bench with adequate power

connected.

Figure 20: LED - D1

Is the Microprocessor heartbeat LED -D1, flashing?

D4 should be on steady- otherwise the unit is resetting

D5 should not be lit – other wise it getting packet errors

D6 should be flashing rapidly – showing the micro processor is awake.

If you connect the GUI with a console cable, are you able to communicate.

Once communication is established:

Do the SFD numbers match?

Are both Administrative channels the same?

Is there an Operating channel set in the “Master”?

Is one unit a “Slave” and the other a “Master”?

Are both rotary switches set on 0?

Are the CDMA codes the same on each pair? (1 through 4)

Are both Data Rates set the same?
