modules stay securely connected.
9.4: Factory Settings and Reset Button
QFactory Settings:
All Nexus I/O Modules are shipped with a preset address and a baud rate of 57600. See below for
addresses.
QReset 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 I/O using the Communicator EXT
software; see the Modbus Communicating I/O Modules User Manual.
