2.4 Connecting the DSM250
The Maretron DSM250 provides a connection to an NMEA 2000
®
interface through a connector that
can be found on the back of the unit. The NMEA 2000
®
connector is a five pin male connector (see
Figure 4). You connect the DSM250 to an NMEA 2000
®
network using a Maretron NMEA 2000
®
cable (or compatible cable) by connecting the female end of the cable to the DSM250 (note the key
on the male connector and keyway on the female connector). Be sure the cable is connected
securely and that the collar on the cable connector is tightened firmly. Connect the other end of the
cable (male) to the NMEA 2000
®
network in the same manner. The DSM250 is designed such that
you can plug or unplug it from an NMEA 2000
®
network while the power to the network is connected
or disconnected. Please follow recommended practices for installing NMEA 2000
®
network products.

2.4.1 Checking the Connection
Once the NMEA 2000
®
connection to the Maretron DSM250 has been completed, observe the
display to check to see that information is being properly received. One way to verify connectivity is to
enter the device selection menu, which is described in Section 5.2.3.2. Refer to Section 0,
“Troubleshooting”, if no information appears.
