1 Introduction
1.1 System Overview
The Models 4050 and 4050R are 5 GHz full-duplex Radio Frequency (RF) modems with link speeds of 64 and
128 Kbps. Data formats are synchronous serial, asynchronous serial, and 10Base-T Ethernet. The Model 4050R is
intended for rack mount applications and includes a two port data sharing feature. The Model 4050 is typically
used as an embedded modem or in standalone applications.
