Use our Modem Splitter to connect six terminals to one modem and save money - you won't need extra modems and extra lines!

No special cables are needed. It uses ordinary straight-pinned cables for a hookup, and includes a 6-ft. DB25 male/DB25 female extension cable and a serial DB9 female/DB25 male AT adapter.

The Modem Splitter is transparent to speed and protocol and works equally well in sync and async environments.

A 3-Port Modem Splitter is also available. See "Similar Products." If you need port contention or advanced features such as prioritized port scanning, see our RS-232 Data Sharers (TL601A-R2) or our Programmable Sharing Device (TL304A).
