Product Features

  • Enables four RS-232 terminal devices to share a single modem.
  • Transmits data received from the modem to all attached terminal devices.
  • Passive, non-powered. Operates transparent to data formats and speeds.
  • Only one terminal device can send data to the modem at a time.
  • Transparent to data formats, rates and protocols.
  • RS232 data output by the attached terminal devices is logically OR gated by the modem splitter and then transmitted to the modem.


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 (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.
