Install Your ArmorBlock MaXum I/O Module
To install 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, DeviceNetManager, or
other software configuration tool. Setting the switches between 64 to 99
allows the software to 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 lastvalid 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.
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
• or other optional cable base assembly.
Important: The cable base should already be installed. See publication
1792D-5.9 to install 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 cap-
tive 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 mod-
ule to the base.
Note: Dimensions change according to the cable base and module
combination used.
Align the
screws to
properly
assemble
the module
to the base.
Cable Base 1792D-CBFM is
used for this example.

Connect the Input / Output Cord Sets to the MaXum Module
This module uses 5 pin micro (12mm) style PCB mounted connectors.
Eight micro caps cover the connectors on your module. Remove the caps
and connect your cord sets to the appropriate ports. This product has two
inputs or outputs per I/O connector. Use a “Y” splitter cable for access to
all I/O connections. For more information on these cables, see the Product
Data publication 1792-2.1
Use the micro caps to cover and seal unused ports. Pinout diagrams for the
connectors are shown next.
!ATTENTION:
• Make sure all connectors and caps are securely tightened
to properly seal the connections against leaks and
maintain IP67 requirements.
• For maximum noise immunity, input and output cable
return wires must be properly terminated. When inputs
and outputs are connected in loopback, return wires
should be connected together.
• I/O cable length should be less than 30 meters.

Output Power and DeviceNet Cables
Output power and DeviceNet cables are described in the installation
publications for the cable base assembly of your choice. Refer to the

Communicate With Your ArmorBlock MaXum I/O Module
This ArmorBlock module’s I/O is exchanged with the master through a
poll, change of state, or cyclic connection.
The module consumes and produces I/O data as follows:
Cyclic - allows configuration of the block as an I/O client. The block will
produce and consume its I/O cyclically at the rate configured.

Publication 1792D-5.20 - October 1998
Polled device - a master initiates communication by sending its polled I/O
message to the module. The 8 input / 8 output module consumes the
message,updates outputs, and produces a response. The response has input
data, input faults, output faults, and the status of the Auxiliary power.
Change of state device - productions occur when an input changes or a fault
condition occurs. If no input or fault condition change occurs within the
expected packet rate, a heartbeat production occurs. This heartbeat
production tells the scanner module that the I/O module is alive and ready
to communicate. Consumption occurs when data changes and the master
produces new output data to the I/O block.
