Section 2 - Installation
The F901 Controller module is wall mountable using M5 or #10 screws. Install the module in the
immediate area where you wish to view the displayed sensor readings. Consideration should be
given to proximity for users to engage the touch screen.
Connect the 5V power adapter to the sensor module by inserting the plug into the 5V power
receptacle.
For TCP/IP communications applications, connect a standard CAT5 communications cable to the
MODBUS
ETHERNET
port. This cable will connect to the comm port on the ACCUSAFE Sensor
module for single sensor applications or to an Ethernet switch or hub for multi-sensor applications.
For RTU (RS485) communications applications, connect a standard CAT5 communications cable
to the MODBUS
RS485
port. This cable will connect to the comm port on the ACCUSAFE Sensor
module for single sensor applications or to the next sensor in the daisy chain for multi-sensor
applications**.
**
NOTE:
Multi-sensor applications using RS485 connections will require a splitter device be used
at each node in the chain using a multi-drop (daisy chain) topology.
