The NMEA 2000
®
connector is a five pin male connector (see Figure 3). You connect the
USB100 to an NMEA 2000
®
network using a Maretron NMEA 2000
®
cable (or compatible
cable) by connecting the female end of the cable to the USB100 (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 USB100 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.

2.5.1 Checking Connections
Once the NMEA 2000
®
and USB connections to the Maretron USB100 have been completed,
check to see that information is being properly transmitted by observing that your computer
software is receiving NMEA 0183 sentences via the USB port. Refer to Section 4,
“Troubleshooting”, if no information appears.
2.6 Configuring the USB100
As shipped from the factory, the USB100 does not require any special configuration and will
work for most applications. However, there are two configurable items in the USB100 which
includes: 1) NMEA 2000
®
to NMEA 0183 sentence translations and 2) NMEA 2000
®
device
selection.
2.6.1 NMEA 2000
®
to NMEA 0183 Sentence Translations
The following table shows the NMEA 2000
®
PGNs received from an NMEA 2000
®
network and
the corresponding translations to NMEA 0183 sentences for use by the PC.
