Black Box TL421A Rs-232 Passive Modem Splitter 4 Port Rj45
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.
The 4-Port RJ-45 Modem Splitter (TL421A) is designed to allow multiple terminals to share a single modem. This passive device is non-powered and transparent to data formats, rates, and protocols. Data received from the modem is transmitted to all attached terminal devices. Only one terminal device may send data to the modem at a time. If more than one terminal device sends data at the same time, the data will be corrupted. Connect the Master port to a DCE device, such as a modem, using an RJ-45 straight-through cable and the appropriate RJ/DB adapter. All other ports, labeled Port 1 through Port 4, connect to DTE terminal devices. When connected to DTE devices, you don't need crossover cables.
NOTE: Only one terminal device can send data to the modem at a time.
