Black Box RS-232 Data Sharer - concent Product Details

With RS-232 Data Sharers from Black Box, you can cut extra modem costs and leased-line charges for your RS-232 system. Simply connect up eight RS-232 devices to one modem and phone line!

This RS-232 Data Sharer features transparent operation up to 64 kbps and convenient LED monitoring. Front-panel switches enable and disable RTS on each input port.

The model features antistreaming circuitry to lock out any port the instant it begins to stream. Hardware-prioritized scanning lets the most frequently used channels go first.

The RS-232 Data Sharer is compatible with various popular IBM communications protocols, such as half-duplex Bisynchronous Communication and Synchronous Data Link Control (SDLC).
