CLB2000 Quick Start Guide
Installation Step 3 - Power
Provide power connections to the unit. Power is connected to the eight core PWR/DATA cable on the Red and
Black wires. The Red wire is the positive (+) connection. The Black wire is the negative (-) connection.
Connect the stripped wires to the nearest source of primary 12V or 24V DC power.
Ensure that the supply is
connected via the supplied 3A fuse or suitable circuit breaker.
Add the fuse in the positive power connection
to the unit if necessary.
The CLB2000 Class B Transponder is designed for a 12V or 24v DC systems.
Installation Step 4
– Data Connections
The CLB2000 can be connected to other AIS compatible equipment via the NMEA0183 connections on the
PWR/DATA cable, via the NMEA 2000 interface cable and/or to a PC via the USB interface.
The USB cable of the CLB2000
should be routed to the Boat’s PC to ensure that there is enough cable length. If
you need to extend this cable, please use a USB extension cable that is no more than 4m in length. The
maximum length of USB cable without the use of a powered extender cable or Hub is 5m.
Please do not plug in the USB cable of the CLB2000 to your PC at this stage. We will cover this in section 4 -
Configuration.

The most common connection to a dedicated chart plotter is to take the NMEA Output 1 ( and Brown
–)
from the CLB2000 Transponder and to connect it to a free NMEA Input on the plotter. You must then tell the chart
plotter that AIS data is connected to this port and set the baud rate to 38,400 Baud
– the standard speed for AIS
data. Consult the instruction manual supplied with your Chart Plotter to understand how this is configured.
