If used for controlling Pro-Bel panels and UMD’s, all daisy chained devices must be
connected to one port and the controller to another.
The terms Controller and Machine are used to determine which wires are used to
receive (RX) and transmit (TX) signals. RS422 connections usually use 9 pin D type
connectors, as follows:
Note: The drawing above refers to the pinout of the connectors with respect to the
controller /machine.
The Freeway RS422 router has two modes of operation, Distributive (Broadcast) and
Non-Distributive (1 to 1), and being a port based router these need to be thought of
from two different perspectives, cabling and control.
As far as cabling is concerned when a device is connected to the router the same
cable connections are used for both modes whether it is a contoller or a machine.
The software within the Freeway router will dynamically configure the ports
depending on how the devices are being used.
From a control point of view the router needs to be considered as sources and
destinations.
When working in Distributive (Broadcast) mode, controllers are treated as sources
and machines are treated as destinations.
The way a device is selected on a control panel (i.e. as a source or as a destination)
will determine how its port is configured. If a device can be a controller or a machine
then it needs to be entered as a source and a destination in the system database and
depending on how it is selected will determine how its port is configured.
