MODEM CHANNEL CONNECTION TEST
This screen allows the user to test communication channels between the RCS20 and all modems
connected to the system. The ** indicates communication is in progress, and will move between all
configured channels before the test is complete.
4.3.1.3.1
Programming steps:
1.
Press <START> to begin the test. The ** will move from Channel 0 to all configured channels.
A ‘Y’ in the ACTIVE Row indicates normal communication, and an ‘N’ indicates communication failure
between the RCS20 and the modems. The MODEM Row lists the communication channels for each
modem. For example, an ‘N’ in the ACTIVE Row under Modem 4 indicates a problem with the modem
connected to Channel 4. Possible problems could be a bad connection to the Modem 4 Remote Port, or
an incorrect address for Modem 4, either at the modem or at the RCS20.
IMPORTANT
This test is performed approximately every 30 seconds by the RCS20, and the ** may
appear without pressing <START>.
