4.2 CONFIGURING THE NODE ID
The Node Source Address (SA) is configured by jumpering the matching Config-A to Config-B. The Node SA starts with a base ad-
dress of
224
(0xE0h) with no jumpers installed. The offset is configured with the use of Binary Coded Decimal (BCD). A power cycle is
required when changing the Node SA. If a duplicate source address is on the network on a power up our module will stay in address
arbitration mode and will not function.
Please note that all devices on the same J1939
network must have a different Source Address
All unused pins need to be plugged with a
DEUTSCH #114017 sealing plug to maintain
the IP67 rating
