The ATC-108N interface converter is compatible with RS232C, RS422 and RS485 standards and allows the conversion of one RS232 channel to RS422 or differential RS485.
The integrated galvanic isolator allows 3500V isolation voltage between RS232 port and RS422/485 interface, and TVS suppressors are able to effectively inhibit surge and electrostatic discharge, thanks to 1000W of protection power.
In this type of converters usually a handshake signal (for example RTS) controls the direction of data from the RS485 side, in this device, instead, it is the internal circuit that detects the direction and automatically switches the RS485 driver, without using any handshake signal. This peculiarity gives the device complete transparency, without having to resort to software modifications to the devices connected to it.
The ATC-108N interface converter can support point-to-point and point-to-multipoint connections. In point-to-multipoint mode, up to 128 RS422/485 devices can be inserted with transmission speeds up to 115.2kbps.
The ATC-108N supports 4 communication modes:
- point-to-point/4 wires full duplex
- point-to-multipoint/4 wires full duplex
- point-to-point/2 wire half duplex
- stitch-multipoint/2 wires half duplex
The power supply can be supplied either through removable terminals or through standard 9Vdc adapter (included) (2.1mm jack).
The product is supplied complete with the following accessories:
- AC/DC power adapter
- RJ45 to DB9F adapter cable (1.2mt)
An adapter is optionally available to allow DIN rail mounting (See figure).

I replaced an excessively long RS232 link with this converter, it works correctly!
Always helpful technicians clarified some doubts for me in no time.
Franz (proprietario verificato) –
The converter works fine but the RJ45 plug is really uncomfortable; the 9-pin socket is F so suppose you connect a DTE; if you have an F port on the device to connect, you have to convert the genre to M and put a "null modem" adapter or find a cable that does this. I hope they put some nice screw terminals or a 9-pin tray that are much more practical.
Lorenzo Raftacco –
Yes, in fact, the product has been designed to convert an RS232 port of a DTE (typically PC) to RS485, and, in this case, it is not necessary to do anything more than connect the supplied cable to the DTE.
