RS-232 Modem Splitter Cards

Used with the RS-232 Modem Splitter Rackmount Chassis - 2U (TL400A), this 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.

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 connect to your DTE terminal devices.

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