The ATC-108N Interface Converter is compatible with RS232C, RS422, RS485 standards and capable of converting single end RS232 signal into RS422/485 differential.
The built in photoelectric isolator allows 3500V isolation voltage between RS232 and RS422/485 I/F, and the Transient Voltage Suppressor (TVS) can effectively inhibit lightning and ESD, providing 1000W lightning strike and surge protection power on each line, and prevent lightning strike and common mode interference.
Connect PC, IPC, or portable computer via a DB9 female connector at RS232 interface, and connect RS422/485 end via convenient 6-pin extractable TB. The RS-485 supports 2-wire half duplex.
The handshake signal (e.g. RTS) usually controls the data direction, but the internal circuit of the device can detect data direction and switch to control it automatically, conveniently to form a RS485 network without any handshake signal. This kind of RS485 control is fully transparent and need no software amendment for the former working modes basing on RS232.
ATC-108N Interface Converter can provide credible connection for point to point and point to multi-point communication. The point to multi-point allows the connection of up to 128 RS422/485 devices with a data transmission speed of up to 115.2Kbps.

The ATC-108N supports 4 communication modes:

1. point to point/4 wire full duplex
2. point to multi-point/4 wire full duplex
3. point to point/2 wire half duplex
4. point to multi-point/2 wire half duplex

The power supply may be connected through a standard 9Vdc adapter (included) (jack 2.1mm) or TB.

The product is supplied with the following accessories:

• AC/DC power supply adapter
• RJ45 to DB9F cable (1.2mt)

Optionally it is available an adapter to allow the DIN rail mounting (See figure).

Applications
	Connection extension of RS232 devices.
	Local networking point-to-point or point-to-multipoint.
	Galvanic insulation of RS232 devices.
