Noland NM42 Connections

A

Noland NM42

NMEA 0183 Multiplexer

 

 

 

B

DB9 Serial Connector

DB9 Terminated to the 8000i Utility cable

 

 

 

C

Power

Power 8 V DC - 28 V DC

 

 

 

D

Baud / Ground Connection

Connect the Baud to ground. This enables

 

 

19200 high speed baud rate

 

 

 

E

NMEA output

Talker. Output to Auto pilot

 

 

 

F

NMEA in

NMEA for Instrument e.g. Heading

 

 

 

G

NMEA in

NMEA for Instrument e.g. Depth

 

 

 

H

NMEA in

NMEA for Instrument e.g. Wind

 

 

 

Connect the following;

1.Power (8 V DC to 28 V DC), check polarity.

2.Baud shorted to GND, as per Commissioning section.

3.Up to 4 NMEA talkers (input to 8000i) to IN1 through IN4.

4.Talkers must be 4800 baud

5.If talkers are single-ended, connect In1- to common ground.

6.1 optional NMEA listener (output from 8000i) to TLK

7.Listener must be 4800 baud

8.If listener is single-ended, leave TLK- disconnected and connect listener GND to common ground.

9.Connect 8000i Utility port to multiplexer DB9 port by constructing a cable with the following pin-out

N.B. OUT+/- port contains the combined talkers at 19200 baud (a duplicate of the DB9 port) and is redundant in this system.

8000i Utility Port

Change the Baud rate of the 8000i processor to 19200 (see "Set NMEA Baud Rate" page 71)

If a listener device is connected to TLK, configure the required 8000i NMEA output sentences (see "Set NMEA Output" page 70)

N.B. the output from the multiplexer is at 4800 baud.

8.3.4External Alarm

Connect 8000i to external alarms. The external alarm output (dark green wire on the NS004801 Utility Cable) switches to ground to sound the alarm. If the current drawn by the external alarms is more than 250 mA, fit a relay.
