Overview

The RS232 IP family of interface converters allows full bi-directional synchronous conversion between RS-232C (V.24) and V.35, X.21 or RS-449/530 hardware. These converters all work WITHOUT an EXTERNAL POWER SUPPLY. The RS232 IP interface converters are designed for synchronous RS-232 operation at data rates up to and including 128kbps. They may also be applied to asynchronous RS-232 using only TD & RD signals, while ignoring TC, RC, and XTC timing signals. Asynchronous RS-232 requires three times greater data throughput on the synchronous side´s V.35, X.21 or RS-449/530 interface. The physical connections for all RS232 IP family converters are DB25 female connectors. The RS-232 side supports direct connection to the DB25 connector with standard pin-out, while an adapter cable is required on the V.35, X.21 or RS-449/530 side to provide the proper interface connection. The V35IP model´s interface does not require balanced signals for the handshaking signals and therefore cannot be adapted for X.21, RS-449 or RS-530 use. However, the 449IP or X21IP models may be interchanged as long as the correct adapter cable is applied.
