Serial Converters are industrial RS-232 to RS-422 and RS-485 converters that are ideally suited for the industrial automation market and other “control panel” applications. Some offer triple isolation and hardened Class 1 Division 2 certification for use in hazardous locations and temperature extremes.

ADAM-4520 

ADAM-4520 - Isolated RS-232 to RS-422/485 Converter 

Automatic RS-485 data flow control 

3000 VDC isolation protection 

Surge protection RS-485 data line 

Transmission speed up to 115.2 Kbps 

LED indicator to monitor status.

The ADAM-4520 converter lets you take advantage of RS-422 and RS-485 on systems originally equipped with RS-232. It transparently converts RS-232 signals into isolated RS-422 or RS-485 signals. You do not need to change your PC’s hardware or your software. The ADAM-4520 lets you easily build an industrial grade, long distance communication system with standard PC hardware. It extends the communication distance by 4000 ft. (1200 m) or increases the maximum number of connected nodes by 32.

BB-422PP9R 

BB-422PP9R - Serial Converter, RS-232 DB9 F to RS-422 DB9 F, Port Powered 

RS-232 to RS-422 converter 

Extends RS-232 line up to 1200 m (4000 ft) 

Data rates up to 115.2 Kbps

DB9 F / DB9 F 

Powered from RS-232 handshake lines – no power supply required.

The BB-422PP9R channel converter changes TD and RD RS232 signals to RS422 and extends data up to 1.2 km. It transmits both ways in RS232 and RS422 system. RS232 pinout connects to computer COM port or other DTE device. Port-powered from RS232 DTR and RTS handshake lines – no power supply or SW required.
