3. Starting with the left module and using a slotted screw driver, fasten the first Output Module to
the left Mounting Bracket. The left Mounting Bracket is the one with the PEM. Fasten the
internal screw tightly into the left Mounting Bracket.
4. Next, slide the female RS485 port into the male RS485 side port to connect the next Output
module to the left module. Fasten together enough to grab but do not tighten.
One by one combine the modules together using the Integrated Fastening System (Fig. 10.1).
If you require an additional power supply, attach a PSIO (power supply) to the right of each
group of 4 Output modules (see Section 10.3).
NOTE: The PB1 can also be used for a Low Voltage Power Supply. It must be mounted
separately.
5. Once you have combined all the Output modules together for the group, fasten tightly.
This final tightening will lock the whole group together as a unit.
6. Attach the right Mounting Bracket to the right side of the group using the small phillips head
screws provided.
7. Then, mount the group of modules on a secure, flat surface. This procedure will ensure that all
modules stay securely connected.
10.4: Factory Settings and Reset Button
Factory Settings:
All Nexus® Output modules are shipped with a preset address and a baud rate of 57600. See the list
shown below, for module addresses.
Reset Button:
If there is a communication problem or if you are unsure of a module's address and baud rate, press
and hold the RESET button for 3 seconds. The module will reset to a default address of 247 at
57600 baud rate for 30-seconds. This will enable you to interrogate the module using the
Communicator EXT software; see the Modbus Communicating Output Modules User Manual.
