3. Installation
The A015-TX is a plug and play device, with no configuration required.
IMPORTANT: Connect the VHF antenna BEFORE connecting any other devices!
Do not connect powered devices to a splitter until the other steps below have been followed in the
correct order. Connecting powered devices to a splitter before the other steps will damage your devices.
1. Remove power source from the A015-TX
2. Remove power source from all devices
to be connected.
3.
Connect the VHF antenna to the Splitter
before adding power or any devices.
4. Connect all other devices (unpowered)
to the A015-TX (ie. VHF radio, AIS transponder and
FM/AM radio)
5.
Power the A015-TX
6.
Power all connected devices
(ONLY do this AFTER following the above steps in the correct
order).
7.
Checking status LEDs
light up when expected.
4. Status LEDs
The A015-TX has four LEDs that indicate power and working status.
The
ERR LED
will illuminate if the antenna has short or open circuit. If this happens, de-power the
A015-TX immediately. Disconnect all connected devices and check if the VHF antenna is well
connected. Then re-follow the steps above. Contact a local installer for a professional help if needed.
For safety purposes, the A015-TX has an automatic VHF fail-safe. This means that the VHF
radio has full priority and will remain functional, even in the unlikely case that the Splitter
would fail or lose power.
