Black Box TL073A-R4 3-Port (MS-3) Modem Splitter

Black Box TL073A-R4 RS232 Passive Splitter, DB25 (F), 3-Port

Use the TL073A-R4 Modem Splitter to connect three terminals to one modem and save money - you won't need extra modems and extra lines! The Modem Splitter allows an RS-232-C DCE device, such as a modem, to interface with up to three RS-232-C DTE devices, such as terminals. The MASTER port is configured DTE and PORTS 1 - 3 are configured DCE. No jumpers and/or switches are located on the Modem Splitter. 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.
