1. Connect the DeviceNet cable to the removable connector as shown.
2. Insert the removable female connector into the mating male connector
on the DeviceNet scanner module.

Scanner Module Power-up When power is applied via the Compact I/O bus, the scanner module goes
through a self test sequence. Upon successful completion of the self test, the
scanner module is ready to communicate.
The default scanner module settings are:
• Communication rate = 125 Kbps
• Node address = 63
Use your configuration software to change the communication rate and node
address.
IMPORTANT
If the 1769-SDN scanner module is the first or last device
connected to the DeviceNet network trunkline, be sure to add a
termination resistor (120
Ω
1%
≥
¼W resistor, Allen-Bradley
part number 1485A-C2) across the Blue (CAN Low) and White
(CAN High) wires.
