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.
