Overview
The computer provides one or more multi purpose RS-232 ports
(9-pin male D-connector) for external interfacing at its rear. On
the Simrad EK60, these are used for:
• NMEA navigation receiver input
• Depth telegram output
• ITI (Integrated Trawl Instrumentation) communication
• Purse seine
• Motion sensor input
• Synchronization
An analogue heave, roll and pitch sensor may be connected
directly to the Auxiliary connector of the nearest transceiver.
A colour printer may be connected to the printer port (25-pin
female D-connector) at the rear of the computer.
NMEA instruments
GPS (Global Positioning System) receivers output NMEA 0183
telegrams containing geographical latitude and longitude. The
defined communication parameters are:
• 4800 bits per second
• 8 data bits
• no parity
• one stop bit
However, most navigation receivers allow different parameters
to be entered.
Connect the navigation receiver to a free RS232 port. Only the
signal (Rx, pin 2) and ground wires (pin 5) need to be
connected.
Connect only the signal wire (Tx, pin 3) and the ground wire
(pin 5) to the sensor’s output.
Maximum cable length is approximately 10 meters.
Trawl system
Communication with the Simrad ITI (Integrated Trawl
Instrumentation) is based on NMEA telegrams.
