Asynchronous half-duplex Non-Powered Interface RS232 / RS485 Converter

Asynchronous half-duplex Non-Powered Interface RS232 / RS485 Converter

Features

* Non-Powered RS 232 / RS 485 Interface Converter

* 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.
