Figure 8: Baseband Signal Timing
The RF input to the receiver is a 50 ohm interface.
The RM RDMS™ also provides a 70 MHz IF output for each channel for troubleshooting purposes. The IF is
resistively coupled from the input of the demodulator. Therefore, the signal level on the IF output should be within 2
dB of the demodulator’s input.
3.4 Remote Control Interface
The receiver’s remote control interface, Remote RDMS
TM
Client (also referred to as “RRC”, or simply “the client”)
is an Ethernet-based graphical user interface that enables configuration and monitoring of one, or multiple, RM
RDMS™ units on the user’s network. The client provides easy-to-read, real-time status information to the user, thus
eliminating the need for direct access to the front panel.
RRC is built upon Microsoft’s ubiquitous .NET Framework, which is a software-based coding foundation that
facilitates consistent application performance across various hardware platforms, as well as enhanced security. .NET
is compatible with Windows XP, Windows Vista, and Windows 7.
To install RRC from the accompanying CD:
1.
Go to the “Remote RDMS Client Install” folder at the root level of the CD.
2.
Double-click on the “Setup.exe” file and the installation will begin.
Depending on the operating system, the user may receive an application install security warning that says the
publisher cannot be verified. Click on the ‘Install’ screen button to continue. Toward the end of installation, the
Windows firewall may ask the user if they wish to block the application. The user should click on ‘Unblock’ to
enable the Remote RDMS™ Client.
Following installation, the program can be found under the following Windows path:
Start > All Programs > Quasonix Tools > Remote RDMS > Client
Windows Vista and Windows 7 include .NET by default; however certain Vista users may still be prompted during
the RRC installation process to install the latest version of .NET, which is included on the CD under the folder
“Quasonix Client Dot Net Support”.
