WARNING
The System Ground signal (Connector J2, Pin 6) must be connected to the
supply voltage ground reference for proper system operation, regardless of
whether any of the Discrete Input signals are connected.
3.4.4 DC Power Connection
Connect a source of DC power with a ring terminal
to the 1/4”-20 stud on the top of the device,
being careful not to torque the connection beyond the specified value of 20 in-lbs. (2.26 N·m).
Ensure that the cable providing the DC power is protected by a fuse or circuit breaker with a
value appropriate to protecting the wire or the 75A maximum specification of the CLMD12,
whichever is less.
3.4.5 Checking Connections
Once all of the connections to the CLMD12 have been completed, check to see that
information is being properly transmitted by observing an appropriate NMEA 2000
®
display. If
you don’t see channel on/off status, refer to Section 6, “Troubleshooting”.
3.5 Configuring the CLMD12
The CLMD12 will transmit data over the NMEA 2000
®
network as it is shipped from the factory;
however, it may require configuration, depending on the type of switches monitored and the
number of similar products on the NMEA 2000
®
network. There are several configurable items
within the CLMD12, which are detailed in the remainder of this section.
You configure the CLMD12 using Maretron N2KAnalyzer
®
or Carling G2Analyzer software. The
following subsections describe the configurable parameters in the CLMD12.
