  1. Device Fail XXX
    RS-485 communications have been lost between the endstation and the device labelled XXX

    [ Top ]



  2. No Comms XXX

  3. MODEM FAULT
    Endstation unable to communicate with COM9600 digimodem.
    If modem not present, ensure that "Disable digi" option is set to 'YES' and "Download Mode" is set to 'NONE' or 'RS232'.
    If present but not detected, check digi-modem is inserted correctly and complete endstation initialisation by pressing endstation 'RESET' button for 2 secs.

  4. Digi Fail Comm
    Call to ARC from COM9600 digimodem has failed
    (Note: This is a communication problem which is rarely caused by an equipment fault)
    Check ALL call details are programmed correctly. Ensure signalling format correctly set for ARC receiver. If only one call number programmed, ensure "STOP ON SUCCESS" = 'YES' and "TRY SAME" is selected - NOT "TRY NEXT".

  5. CHC TEST FAIL
    Unable to initialise SMS messaging with Castle Host Computer
    Ensure Digi is enabled, and at least one SMS call is correctly programmed. Ensure "Disable Digi/SMS" is set to 'NO'. Check that ordinary phone on same line connects to CHC and that modem tones are heard - if not, problem is PSTN - NOT equipment.
    De-programme SMS content types for each call, exit engineer menu, press RESTART button, and retry CHC test from manager menu.
    NOTE: This would also result if telephone line had premium rate calls barred, or customer had "BT Answer 1571" enabled. Non BT lines can fail to communicate with CHC.
