MVRD Local Control
4.1
Introduction
As with all GMS Cobham surveillance products, the MVRD uses “Set-Up Groups”/ “Profiles” (Up to 16) to
allow the receiver to be completely pre-configured by Administrators prior to deployment. These set-
up groups define all of the operating parameters (e.g. frequency, bandwidth, FEC, Decryption On/Off)
available to the users. Users on both the TX and RX side only need to be directed to which set-up group
number to use. Normally, the TX and RX would each use the same set-up group number.
GMS offers several control options, including local control and M.S. Windows Applications for remote
control and status monitoring.
The MVRD’s front panel display and keyboard are used for both local control and status monitoring.
The MVRD has a local control panel that allows the selection of up to 16 set-up groups/configurations.
Status indicators are provided for RF Signal Strength, Demod lock, SNR, the presence of a Transport
Stream, audio, video, data, and Decryption Active. This section describes the various displays and
controls that are used for local control. Refer to
