General Information
Featuring multiple ports for splitting modem signals, the compact 4-Port Modem Splitter (RS-232 on RJ-45) makes it easy and affordable for four terminals to share a single modem.

With it, you can avoid the cost of having to purchase and install multiple modems and multiple modem lines.

Plus, 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.

NOTE: Only one terminal device can send data to the modem at a time.
