The Trycom TRP-C06 allows an RS-232C line signal to be optically isolated and bi-directionally converted to RS-422 or RS-485 standard and communicate data along twisted pair lines up to 1.2Km in length. This makes it ideal for connecting your PC to RS-422 and RS-485 control networks.
The intelligent device automatically switches the RS-232 baud rate and direction flow control for RS-485.
It is competitively priced and available with free shipping to the UK and EU by standard delivery.
