2. Introduction

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.
