4: Troubleshooting the 4092A

Perform all of the following procedures before returning the unit for service. If the unit still appears to have a problem, call Timing Solutions Corporation and request technical support. Have the serial number of your unit ready to give to a technical representative.

4.1 Troubleshooting Input Problems

As long as the 4092A is in autoswitch mode and has two valid input signals connected, the unit will automatically switch to the other input channel if it stops receiving a valid signal on the active channel.

If the unit loses the active input signal, the LED for the that input turns red until you correct the problem. To correct the problem, you must ensure that the channel is receiving a valid signal and reset to the autoswitch mode.

Table 3 shows the INPUT LED states, their definitions, and actions required. Table 4 shows the INPUT SELECT LED states, their definitions, and actions required.
