2.4 Connecting the J2K100
The J2K100 requires two electrical connections as shown in Figure 2. Refer to Section 2.4.1
for making the NMEA 2000
®
connection and Section 2.4.2 for making the J1939 connection.
Figure 2 – J2K100 Electrical Connections
2.4.1 Connecting the J2K100 NMEA 2000
®
Interface
Vertical text on the J2K100 label identifies the NMEA 2000
®
connector. With the label right
side up, the NMEA 2000
®
connector can be found on the right side of the enclosure. The
NMEA 2000
®
connector is a five pin male connector (see Figure 3). You connect the J2K100
to an NMEA 2000
®
network using a Maretron NMEA 2000
®
cable (or compatible cable) by
connecting the female end of the cable to the J2K100 (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 J2K100 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.
