Cable 16
The CAN bus cable must be of a paired and twisted type designed for the purpose. The CAN
bus cable can handle signals up to 100
m away from the VHF to further Control Speaker
Microphones (CSM).
Only 1 CSM can be connected to the VHF with a CAN bus cable of max 100 m if the cable
dimension is 0.5mm
2
of each cord. Other combinations with more CSMs must be calculated
seriously before installing the cable. If more CSMs are connected, the CAN cable of 0.5mm
2
can handle the signals up to max. 100 m. The only restriction is the power supply for the
connected CSMs.
The voltage drop along the cable increases with the length of the cable. Separate supply
cables can be installed in parallel with the CAN cable to reduce voltage drop in long cables.
The maximum allowed voltage drop from VHF to CSM is 2
VDC. It means 1 VDC forward
and 1 VDC return.
Max current consumption for each CSM is 0.5A.

Cable 17: CAN cable for bulk head installation.
Same cable as cable 12, but the plug is removed and the wires are connected to the
connection box.
Same pin configuration as cable 8. See Cable specifications for cable 8 (CTRL) on page B-
