8.8 RS485 – line terminals

Some network installations may require a line termination resistor to be connected across RS485

lines A and B. A 12OR resistor is available with SW4 set to off as standard, highlighted below.

8.7 RS485 – output signals

The Air XD provides in and out RS485 terminals to allow ‘daisy-chaining’ of multiple MODBUS

devices.

For example: ‘Pin 11’ is common with ‘Pin 13’.
