Install Your ArmorBlock MaXum I/O Module

To install the module:

• Set the node address

• Mount the module to the cable base

• Connect the cord sets

• Communicate with the module

Set the Node Address

Valid node addresses are 00 to 63.

Set the node address using the rotary switches, RSNetWorx for
DeviceNet™, DeviceNetManager™, or other software configuration
tool. Setting the switches between 64 to 99 lets the software have
address control.

Each module is shipped set for node address 63. The switches are
located on the underside of the module. The two switches are:

• MSD (most significant digit)

• LSD (least significant digit)

To reset the node address, use a small blade screwdriver to rotate the
switches. Line up the small black dot on the switch with the number
setting you wish to use.

The rotary switches are read at module power up only. Settings
between 64 and 99 cause the module to use the last valid node
address stored internally. Example: The last setting was 40. If a
change is made to 68, and then you power up, the address will
default to 40.

See the illustration of the node address setting below.

Example: Node Address is set at 62, see small black dots.

30703-M

The module is equipped with AutoBaud detect. AutoBaud lets the
module read the settings already in use on your DeviceNet network
and automatically adjusts to follow those settings.

Install the Module

This module mounts to the following cable bases:

• 1792D-CBFM for KwikLink™ flat media installation

• 1792D-CB12 for 12mm drop cable installation

• 1792D-CB18P for round media DeviceNet and output power

• 1792D-CB18PT for 4 connector blocks needing round media

DeviceNet and output power

• or other optional cable base assembly

IMPORTANT

The cable base should already be installed. See
publication 1792D-IN009B-EN-P for more
information on installing the cable base.

To install the module:

IMPORTANT

Proper alignment of the screws is necessary to
complete the connections between the module
contacts and the cable contacts.

1. Position the module over the mounted cable base. Align the

three captive screws in the module with the accepting
receptacles in the base.

2. Tighten the screws with a torque of 8 inch-pounds to secure

the module to the base.

Note: Dimensions change according to the cable base and module
combination used.
