Installation manual

Simrad ES60

Navigation system interface

GPS (Global Positioning System) receivers output NMEA 0183

telegrams containing geographical latitude and longitude. Most

navigation receivers also allow different parameters to be entered.

Wiring procedure

1 Locate a free RS-232 serial port that can be used to connect

the navigation receiver.

2 On the ES60 computer, connect the receive signal

Rx on

pin 2, and

ground on pin 5.

3 On the GPS system, connect the transmit signal

Tx on pin

3, and

ground on pin 5.

4 Ensure that the length of the cable does not exceed

approximately 50 meters. If a longer cable is required, you

may need to use buffer ampliﬁers on the serial li ne.

Setup procedure

1 Refer to the documentation provided with the GPS system,

and establish which NMEA sentence(s) that are used for

communication.

2 On the ES60, access the

Install menu, and open the

Navigation Interface dialogue box.

Position Input Protocol, select NMEA.

• By default, all NMEA sentences are read. If you wish

to read only one sentence, click the

Advanced button

to choose.

4 Click the

RS232 button to open the RS232 Setup dialogue.

5 Enter the identiﬁcation of the RS-232 port you have used

to make the connection.

6 Enter the correct communication parameters, and click

OK.

7 Ensure that the transmit parameters on the GPS system

matches t he receive parameters on the ES60.
