only mode. A remote switch and LED indicator can be connected to the transponder through
the DC/DATA cable as shown on page 20. A USB connection (mini B-type) is also provided.
For best performance and an easy installation a suitable place should be found were the
installations can provide:
1. Short cable-runs for the VHF and GPS antenna.
2. Easy access to DC power.
3. Access to other equipment to which you may wish to connect the transponder to.
To avoid interference from other equipment on board such as generators, compressors or
electrical panels the unit should
not
be installed together or close to such equipment.
The accompanying installation software provides a diagnostic program which can be useful
to diagnose a situation where the transponder is experiencing interference. Read more about
this in

” section in the chapter on the proAIS software.
To ensure that best performance is obtained it is important to choose good antenna cables.
For shorter lengths RG58C/U is sufficient. For cable lengths exceeding 10 m, a low loss
cables should be used, such as type RG213, RG214, or LM400, depending on length. It is
also important to use proper connectors, where crimp type connectors are preferred over
soldered connections. Ready-made 10 m lengths of RG58C/U type cable can conveniently
be used. Ready-made lengths with FME type connectors are available where adaptors for
the different kind of coaxial connectors used can be fitted. In this way an easy-to-assemble
cable/connector kit can be put together for a specific installation without any special tools.
True Heading can provide ready-made kits, cables and connectors.
