Comar Systems ASR 100 User manual

Installation:
The ASR 100 Receiver Antenna Splitter allows your existing
VHF antenna to be used by both a VHF radiotelephone and
an AIS Receiver.
The unit is not waterproof and should be mounted in a dry
location. The unit can be fixed by the 4 mounting holes in the
end flanges.
It will require connection to the boats DC supply of 12-24
Volts. It is recommended to connect it to the same circuit as
your existing VHF Radio.
RED Positive +
BLACK Negative –
Remove the existing antenna connection from your VHF Radio
and plug this connection into the Antenna connection on the
ASR 100. Take the 1m VHF cable from the ASR 100 and plug
this back into your VHF radio. The AIS cable fitted with a BNC
connector can now be plugged into your AIS Receiver.
Operation:
On applying power to the ASR 100 reception is now possible
on both your VHF Radio and your AIS Receiver.
When the transmitter is operated on the VHF Radio the AIS
reception will stop. Reception on the AIS receiver will start
immediately you stop transmitting.
In the event of a fault or power failure to the ASR 100 the
VHF Radio transmit and receive will continue as normal.
