Overview: The SER-485 Lite is a cost

effective adapter to convert bidirectional

signals from RS232 to RS422 and RS485. In

RS485 mode the data direction is managed

by the bitrate adaptive function of ART

(Automatic Receive Transmit control). ART

analyzes the data in real-time, and adapts

to the setup of the RS232 port.

With SER-485 Lite standard operation modes

are selected by simple DIP switches. The

full versatility is controlled by a built-

in software configuration menu, which is

accessed via terminal programs. The

behaviour of RS422 and various options of

RS485 are selected by an easy-to-use menu

structure.

The internal termination and BIAS

(polarization) resistors allow to prepare

the RS485 signals for connection to

customers networks.
