Black Box TL421-C 4 Port RJ45 Modem Splitter Card

Used with the RS-232 Modem Splitter Rackmount Chassis (TL400A), this TL421A-C splitter makes it easy and affordable for four terminals to share a single modem. With this system, you can avoid the cost of having to purchase and install multiple modems and multiple modem lines.

It's easy to set up and use. There are no user-configurable switches, jumpers, or settings on the modem splitter. Simply connect the modem and terminal (DTE) devices to it, then power up your modem and terminals as normal. The splitter's master port connects to your modem using an RJ-45 straight-through cable and the appropriate RJ or DB adapter. Its other ports (Port 1 through Port 4) connect to your DTE terminal devices.
