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
6.1 optional NMEA listener (output from 8000i) to TLK
7.Listener must be 4800 baud
8.If listener is
9.Connect 8000i Utility port to multiplexer DB9 port by constructing a cable with the following
8000i Utility Function | 8000i Utility Wire Color | DB9 Pin Number |
TX+ | White | 3 |
|
|
|
GND | Black | 5 |
|
|
|
RX+ | Yellow | 2 |
|
|
|
RX- | Black / White | 5 (Common with |
|
| ground) |
|
|
|
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.
