Extremely low-cost device for interface conversion from RS232 to RS422/485. The converter has a DB9-F connector that can be plugged into the DB9-M connector of the DTE port (PC Example) to provide a 4-terminal RS422/485 interface. The device has galvanic isolation between the RS232 interface and RS422/485 and is available in two versions:
- ATC-105 RS232-RS422/485 Converter (Optical Isolation)
- ATC-105N RS232-RS422/485 Converter (Electromagnetic isolation)
Features
