Page 4.8 FS 20/25 Installation, System Set-Up and Test

Kongsberg Simrad Mesotech Ltd.

Port Coquitlam, BC - Canada

D- In the “FS25” position, 200 VDC will be provided to the trawl cable. You

select the FS25 position when you have a FS900/FS925 Housing under

water unit connected to the trawl cable, utilizing a FS925 forward-looking

sonar head and an FS3300, TS10, TS15, or TS15S sonar head and a sensor

module.

Note!

To test the FS25 trawl sonar heads connected to the test cable,

you will have to position the voltage selection to FS20.

Warning!

. If you connect an FS3300 330kHz or 120kHz sonar head to the

trawl cable with the switch set to FS25, 200 VDC, you will damage

your trawl sonar head. The FS25, 200VDC, will be used with an

FS 925 90kHz Stand Alone Sonar Head, or a full FS900/925

Deployment Package with any combination of Vertical Heads

(FS3300, TS10,TS15 or TS15S) connected to the trawl cable.

4.2.10 Connection to Cable Winch/Slip-Rings

The connection between the FS 20/25 TTM Interface unit and the cable winch/slip-

rings should be made with an 18 GA., or heavier, shielded twisted pair cable. The

connection to the control unit is made using the 3-pin MS connector supplied in the

TTM module accessory kit. To minimize noise interference on the cable, the shield

of the cable should be attached to the connector.

Note!

The shield of the cable between the FS 20/25 TTM module and

the slip-rings should be connected at the TTM module, but NOT

at the slip-rings.

4.2.11 Interfacing to a Simrad Echo Sounder

The FS 20/25 HP PC processor may be connected to a Simrad echo sounder for

display of the trawl unit depth on the sounder. This is made via the RS232 serial

port “B” on the rear panel of the control unit (DB-9 connector labeled "RS-232" “B”

port). The processor will output the Temperature and the Depth from the trawl

sensor module in an NMEA 0183 format.

If the port “B” is not available, you will have to install an additional serial card. The

recommended type of serial card to install and the installation procedure are provided

in Part 7 “Attachments”. Interconnect cable not supplied.
