IRIS-RS485 – Getting started 

IRIS RS-485 is part of the IRIS product series and is developed for relaying data via radio from 

RS-485 systems to other RS-485 systems or systems connected to other IRIS products. The IRIS 

series contains several models that provide solutions to all kinds of applications. All IRIS models 

can communicate with each other via radio - in pairs or in more complex radio networks.

Getting started

Connect the serial interface (half duplex or full duplex, see picture below). 

Connect the power supply. The polarity of the power does not matter.  

Connect the signal ground pin. 

If needed connect the termination jumper. (See IRIS-RS485-Manual for more information)

Place the IRIS-RS485 so that the antenna is not shielded.  

Avoid metal plating close to and between the antennas.

IRIS-RS485 – Product description 

IRIS-RS485 can be used with both RS-422 and RS-485 systems depending on the configuration. 

The most common use of IRIS-RS485 is a pair of IRIS-RS485 that relays data between two RS-

485 systems. This is however not the only application where an IRIS-RS485 can be used. The 

data can be directed to a PC via an IRIS-RS232 or an IRIS-USB, to a database on the Internet 

via an IRIS-CUW or it can be used to control the outputs on an IRIS-IO. With functions like timers, 

counters and text matching the IRIS-RS485 can be setup to fit many different applications.
