Chapter 1. INTRODUCTION
1.1 SkyWire Product Overview
This manual provides detailed information for the Radyne SkyWire MDX420 Satellite Network Gateway.
When describing the SkyWire gateway, it will be referred to as “the MDX420”, “the gateway”, “the network
gateway”, or “the satellite gateway”. The next few sections will describe theory of operation, setup,
accessing and monitoring the gateway.
The Radyne SkyWire MDX420 Satellite Network Gateway (
Figure 1-1 SkyWire Satellie Network
Gateway ) is a Closed Network Time Division Multiple Access (TDMA) Satellite Gateway specifically
designed for satellite IP networks.

This satellite gateway combines unsurpassed performance with user-friendly remote access. Monitor and
Control (M&C) functions are available through a secure SNMP V1, V2 or V3 interface. Operating
parameters, such as symbol and data rates, FEC code rate, modulation type, IF/RF frequencies, and
three levels of capacity management can be readily set and changed through the user interface by
authorized earth station operations personnel.
The gateway operates over a data rate range of 328kbps to 21.6Mbps with a symbol rate range of
256ksps to 10Msps.
The gateway's data interface is an Ethernet Bridge 10/100/1000 Base-T interface.
The gateway supplies DC power to the LNB. The gateway has an optional feature to supply 24 or 48
volts to the BUC and an optional feature for a high stability 10MHz reference to the BUC and LNB. The
capability to enable and disable the BUC/LNB voltages and 10MHz reference is available via the Ethernet
SNMP control port. In addition, the gateway monitors both the current and the voltage at the output of the
Tx and Rx Ports, thus providing the user verification of overall system status.
