NETWORK VP ISSUE: faceplate not communicating with central computer

To power down a Network VP system, flip the circuit breaker on the power supply inside the cabinet to the "Off" position.


  • Check the RX/TX indicator lights on the modem. Normal operation is for the RX light to come on often and the TX light to come on occasionally.
  • If both lights remain off…
    • Check the fuses on the modem.
    • If the fuses are good, check the field communication wires and connectors for breakage, loose connections, and/or corrosion.
  • If the RX light comes on often, but the TX light never does…
    • Check the satellite CSG and satellite Address by going into the Satellite Settings screen, then advancing to the CSG and Satellite Address functions. Correct them if necessary.
    • If the trouble persists, move the modem to a known functioning satellite to determine whether or not the fault lies with the modem. If so, the modem must be repaired or replaced.
    • If the modem is functioning properly, move the faceplate to the known functioning satellite to determine whether or not the fault lies with the faceplate. If so, the faceplate must be repaired.
    • If the faceplate is functioning properly, move the faceplate-to-modem cable to the known functioning satellite to determine whether or not the fault lies with this cable. If so, the cable must be replaced.
