Overview: The SER-485 PRO is an adapter to

convert bidirectional signals from RS232

to RS422 and RS485 in industrial

environments. 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.

All options and parameters of SER-485 PRO

operation are configured by software,

controlled via an easy-to-use menu

structure. This menu is accessed via

standard terminal programs. The SER-485

PRO is a NO Jumper type of device.

With SER-485 PRO often used operation

modes are selected by simple DIP switches.

The full versatility is controlled by the

built-in software configuration menu. 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. These internal

resistors are activated by relays,

controlled by the configuration menu.

There is no need to open the case for

configuration.
