850-164696 / A

Using two or more GPTs: An Ethernet switch is required if

your system includes more than one General Purpose

Transceiver. in this case, use “straight” ethernet cables between

the computer and the switch, and between the switch and each

transceiver.

Ethernet connection to sensors and other peripheral devices

must be made with a second network adapter in the computer.

5) Interfaces

Connect navigation receiver, trawl system, heave sensor and

other peripherals with serial line output to the rear of the echo

sounder computer using RS-232 cables. The same information

may also be accessed on the ship’s network, but your echo

sounder computer must then be equipped with a second ethernet

adapter.

Heave sensors with an analogue output are connected directly to

the Auxiliary connector of the nearest General Purpose

Transceiver (GPT). If you have more than on GPT, the sensor

shall only be connected to one of them.

5) Synchronization

Synchronous transmission is desirable if there are several echo

sounders onboard the vessel. For every echo sounder and every

transceiver onboard the ship, connect the appropriate pins at the

Auxiliary connectors together using a two-wire cable. A serial

port may also be used to allow synchronization.
