When operated under XP95 or Discovery Protocols, EN54-13 type 2 devices
can be connected. In case EN54-13 type 1 devices need to be connected
they must be installed directly next to this module, with no transmission path
according to EN 54-13.

Troubleshooting
Before investigating individual units for faults, it is important to check that
the system wiring is fault free. Earth faults on data loops or interface zone
wiring may cause communication errors. Many fault conditions are the
result of simple wiring errors. Check all connections to the unit.
