Detailed Product Description

AN-PP-RS-232-485 is a lightweighted, compact and robust port poweredRS-232 to RS-485 Interface Converter. AN-PP-RS-232-485 has a DB9 femaleconverter for RS-232 port, and 6 screw terminals connector or DB9 maleconnector for RS-422 differential input and output interface.AN-PP-RS-232-485 can convert TD and RD signals into balanced fullduplex RS-422 signals.

Model AN-PP-RS-232-485  is powered fromRS-232 data TD or handshake lines. Unit will get the power from RTS orDTR (at least +5.5V or -5.5V).
