RS-232 to RS-422 / RS-485 Serial Converter w/ Switching Power Adapter & 2000V DC Optical Isolation

Converts RS-232 to and from RS-422 / RS-485

• RS485 bit-rate adaptive ART (Automatic Receive Transmit control)
• LED indicator for Power and signals
• Internal Termination and BIAS RS422 with Hardware handshake
• Software Configuration menu for parameters, quick configuration for standard modes DIN-Rail mountable

Product Overview:

The SER-COMi-M 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-COMi-M 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 behavior 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.
