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.
