Port Powered RS-232 to RS-485 Interface Converter (4-Bit Terminal)
Quantity
Description
AN-PP-RS-232-485 is a lightweighted, compact and robust port powered RS-232 to RS-485 Interface Converter. AN-PP-RS-232-485 has a DB9 female converter for RS-232 port, and 6 screw terminals connector or DB9 male connector for RS-422 differential input and output interface. AN-PP-RS-232-485 can convert TD and RD signals into balanced full duplex RS-422 signals.
Model AN-PP-RS-232-485 is powered from RS-232 data TD or handshake lines. Unit will get the power from RTS or DTR (at least +5.5V or -5.5V).
