3.4.........................................IR/SERIAL port connection
In some installation where the proper serial ports are not available and where there is no need to use
the status-reading commands, it is possible to control relayCUE-8 from IR/SERIAL one way
communication port on ipCUE.
The cable for connection to ipCUE IR/SERIAL port needs two wire connections, see picture below:
Please pay attention to the following notes when using this type of installation:
1. cable for this connection is : pin 1 on IR/SERIAL connector on ipCUE is connected to pin 2+3
on SERIAL port connector on relayCUE-8 and pin 2 on IR/SERIAL connector on ipCUE is
connected to pin 1 on SERIAL port connector on relayCUE-8.
2. only one relayCUE-8 unit can be driven from one IR/SERIAL port!
3. commands for reading relay or input statuses have no effect !
