Antenna interface on the terminal

The antenna interface on the terminal connects to the SAILOR Fleet One antenna. The

connector on the terminal is a TNC female connector. An antenna cable (10 m) is included in

the delivery.

To connect the antenna to the terminal

1. Connect the antenna cable between the Antenna connector on the terminal and the

connector on the underneath of the antenna.

2. Where the cables are exposed to mechanical wear - on deck, through bulkheads, etc. -

protect the cables with steel pipes. Otherwise, follow standard procedures for cabling in

ship installations.

For information on alternative cables and how to install and connect the antenna, see Install

the antenna on page 13.

DC power input

The DC power input for the terminal is a 10.5 - 32 V DC; 11.5 A - 4 A input with a remote on/off

function. The input is protected against reverse polarity.

There are different options for the power supply:

• The 24 V DC ship supply provides power for the terminal.

• A 12 V DC supply provides power for the terminal. Note that the maximum allowed source

impedance is much lower for a 12 V DC supply than for a 24 V DC supply. Also, the total

output power available for Power over Ethernet is limited when the power supply is 12 V

DC.

• A 230 V AC supply provides power through an AC/DC power supply.

Be aware of high start-up peak current: 20 A at 24 V, 5 ms.

The terminal is equipped with an internal 20 A Fuse, so no external fuse is necessary in order to

protect the terminal. However, in order to avoid short circuit in the power cable/connector, the

ship’s DC outlet should be protected by a 30 A fuse or circuit breaker.
