The RS232IP 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 RS232IP interface converters are designed for synchronous RS-232 operation at data rates up to and including 128kbps.

The V35IP-CAB interface converter allows full bi-directional synchronous conversion between RS-232C (V.24) and V.35 hardware. These converters all work WITHOUT an EXTERNAL POWER SUPPLY. The V35IP-CAB interface converter is designed for synchronous RS-232 operation at data rates up to and including 128kbps.
