8.5 NMEA Input Wiring
Refer to the manufacturer’s manual for the devices you wish to connect to the NTWB2 for wire
colour and connection information. This manual only deals with the NTWB2 connections as it is
impossible to cover every potential combination of devices to be connected.
8.5.1 Input 1
Connect instrument data wires NMEA A/+ and NMEA B/- to the IN1 + and IN1 – terminals as per
Table 3
. The location of the IN 1 terminals is shown in
Figure 7
below. Ensure the baud rate of the
transmitting device (talker) being connected is 4800.
8.5.2 Input 2
Connect instrument data wires NMEA A/+ and NMEA B/- to the IN2 + and IN2 – terminals as per
Table 3
. The location of the IN 2 terminals is shown in
Figure 7
below. Ensure that Switch 1 is set to
match the baud rate of the transmitting device (talker) being connected (4800 or 38400).
8.6 NMEA Output Wiring
Connect data wires NMEA A/+ and NMEA B/- to the OUT + and OUT – terminals as per
Table 3
. The
location of the OUT terminals is shown in
Figure 8
below. Ensure that Switch 2 is set to match the
baud rate of the receiving device (listener) being connected (4800 or 38400).
