2F. Fault Finding
Note*5
There appears to be no communications coming out of your computer.
Check the RS 232 cable possibly the easiest way would be to try another one
Are you using an USB to RS232 converter if so check that it is present on the device manager list and
what comms port is it assigned to. Using the Help feature window provides type in device manager.
Also have the drivers that come with the converter been installed see the manufacturer’s info.
Intermittent Faults
Intermittent faults are somewhat harder to diagnose.
Check the following, which have proven to be some of the more common issues:
C-Bus cables all correctly terminated and dry.
Check C-Bus voltage is in the correct range.
Add one extra unit at the far end of the C-Bus to see if the network fails. If either of the above, add
additional power supply.
Check voltage as below:
+
C-Bus
-
Each reading should be similar, if not, look for one of the C-Bus lines gone down to earth. Possibly
twisted around front plate screw of key input unit.
