2.4.2 Connecting the J2K100 J1939 Interface
Vertical text on the J2K100 label identifies the J1939 connector. With the label right side up,
the J1939 connector can be found on the left side of the enclosure. In order to make the J1939
connection, you will need to locate the supplied female field attachable connector. This
connector is fitted to one end of a 3-conductor cable (not supplied). Make the connections
between the 3-conductor cable and the field attachable connector by following the instruction
contained within the bag. Although the field attachable connector has 5 terminals, you only
need to connect the CAN bus signals and ground signal (NET-H, white terminal; NET-L, blue
terminal; and ground (or NET-C), black terminal). The other end of the 3-conductor cable
needs to be tied into the J1939 network. You will need to identify the CAN bus signals on the
J1939 network by reviewing the manufacturer’s documentation. Most likely, they will identify
the CAN bus signals as CAN-H and CAN-L which correspond to the field attachable terminals
NET-H and NET-L respectively. You will also need to connect the NET-C or ground signal
found within the field attachable connector to the J1939 ground connection. See Figure 4 for
J1939 connector pin assignments
