RS232 TO RS485 Converter,Commercial Version no power need RS-485 To 232 DB9 COM

HEXIN

Electronic interface: At the side of RS-232 is a DB9 female (hole-type) connector. At the side of RS-485 is a DB9 male (needle-type) connector, with connection board.

Uses with this item Adding an RS-485 interface to a PC via RS-232 is now a snap.

This interface converter does this without requiring any AC or DC power.

Features a female DB9 connector(EIA/TIA), thus allowing it to be plugged directly into any one of the PC's Com ports.

It uses a particular pump to gain power from RS-232 signal (RTS, DTR, TXD) without initializing the RS-232 series interface.
