TMS 'SW2' terminal has a red wire connecting to Teledyne alarms port pin 7 (Tx Inhibit aka mute).TMS 'GND' terminal may have a green wire that would need to be connected to Teledyne alarms port pin 15 (ground).TMS 'GND' terminal has a black wire connecting to Teledyne alarms port pin 2 (ground).The antenna controller pins are likely in the correct spots if this cable is in use. This description assumes the old Comtech-supplied modem cable is being modified to handle the Teledyne alarms port that has slightly different pinouts than the Comtech modem. Sometimes stray commands trigger this bizarre behavior.Īs a baseline, all antenna controllers and terminal mounting strips need to have the following configuration. Try unplugging any cables to a computer talking to the DAC's M&C port (possibly to DacRemP) and pluging it back in. If bit errors are increasing quickly (about 10/sec), but all appears normal, it may be related to some sort of activity on the serial control port. As such, the error count is really only significant when they increase steadily (1 count every few seconds or faster). The wrapping nature of the count makes it difficult to compare one number to the next unless the value is continually watched to see when it wraps around again. Since bit errors do occur from time to time, having a non-zero number is normal and the occasional increase is also normal. Those errors count up from 0 to 255 then wrap back to 0. For larger problems, the number increases more rapidly. For a little hiccup, the number is increased once.

Errors on the left side of the error display screen are 'bit errors' or 'comm errors' that indicate a minor problem communicating between the dome and the antenna controller.
