Troubleshoot Communication Issues
If communication difficulties arise, review the check list below to eliminate some potential
installation errors:
Remote Location
 Verify all jumpers on the control boards and the CIMs are properly configured
 Verify all wiring and terminal block connections are correct
 Have you programmed the NETCOM device with the correct IP address, gateway if
required, and ports
 Have you programmed the NETCOM with the same encryption key as the host location
 Have you programmed the control board with the correct host-location IP address
 If the remote location has a router or end-point device, verify the port settings are
correct for inbound/outbound communication
 Run a diagnostic on CIM 0 - jumper ON J2. LEDs B3— B0 will indicate potential
faults—refer to the CIM Installation Guide.
 If B3 and B0 illuminate during the diagnostic cycle, the data carrier detection
connection is lost. This generally indicates a network connectivity issue
Host Location
 Has the Reverse Network license been registered
 Is the host location running the encrypted reverse network communication manager
 Has the host location entered the same encryption key in the Keyscan Settings utility
software
 Does the host location have a valid network path from the PC/server with the
encrypted reverse network communication manager via any router/end points to the
NETCOM6P/CIM 0/control panel including the correct port settings for inbound and
outbound communication
Note
You may require the services of a network administrator to resolve network issues and
ensure the PC/server with the encrypted reverse network communication manager at the
host location has a valid path and connectivity to the CIM 0/NETCOM6P/control board at
the remote location.
