Section 6: Intermittent Polling on 202 and FSK Lines

1. Bad connections on FSK or 202 lines may be caused by decibel levels that are set too low or too high. Connect a VF meter to the line and adjust the signal level.
2. If there is no level problem, the bad polling is most likely caused by a wiring problem.
3. When you're troubleshooting wiring, the first question to ask is "Is the wiring new or old?"
4. If the wiring is new, check for pinched wires, broken wires, bad soldering and pinout errors.
5. If the wiring is old and it was working well before, check if anything has changed. Has anyone moved anything? Has anyone cleaned up any wiring?
