Communication overview
All Phason networkable devices communicate with the computer using four-wire RS485 serial
communication. The RS485-FD provides a way for the Phason software on your computer to
communicate with the devices along a communication channel.
A communication channel is a continuous line of cable connecting all devices in the series, in other
words, a “daisy chain”. The last device on a communication channel must have the termination
resistors in place, or a termination module installed.
Phason has two types of communication systems.
Single-channel:
OMNI Select, FlowMiser, and SupraWare
Multi-channel:
OMNI Select (optional)
Single-channel systems
A single channel system consists of the computer, RS485-FD Converter, and the Phason devices.
The last device must have the termination resistors in place, or a termination module installed.
