Description
The RS232 to RS422/RS485 Converters represent a hardware solution to the problem of converting signals between two standards. Data transfer can take place at up to 1200m (4000′), over four or two wire cable for full or half duplex, respectively. The converters can handle any RS-485/RS-422 device allowing it to function as a short haul modem or interface converter. Request to send (RTS) selection allows up to 32 receivers to be set up in a multidrop installation, making for a cost effective network configuration.
- Data Transmission Controlled by the RTS Signal
- DCE/DTE Selectable
- Point to Point, Multidrop and Simplex/Duplex Link Selectable
- Four Wire Full Duplex / Two Wire Half Duplex
- Compact Size
