Install a 1769 DeviceNet Communication Module Chapter 2
Connect the Module to a
DeviceNet Network Follow these steps to wire the DeviceNet connector.
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.
3. Screw the removable connector to the scanner case with the upper and
lower mounting screws with a torque of 0.6…0.7 N•m (5…6 lb•in).
Set the Node Address Set the node address using one of these methods:
• For the 1769-ADN, use the node address rotary switches as described in
Set the Node Address of a 1769-ADN Module .
• For the 1769-SDN, use RSNetWorx for DeviceNet software as described
in Set the Node Address of a 1769-SDN Module . The 1769-SDN module
has no hardware mechanism to set its address.

IMPORTANT If the 1769-SDN 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 catalog number
1485A-C2) across the blue (CAN Low) and white (CAN High)
wires.
