1. Introduction
The Radiant Communications Corp. QRF5000 series is a highly integrated, technologically advanced family
of products used to insert one or more local video feeds into a digital cable system. The QRF5000 series
consists of several products which work seamlessly together, or completely independent, to fulfill specific
individual requirements in a cost effective, efficient and flexible manner.
QRF5000
Video is encoded with up to four high quality, real time, hardware based, MPEG-2 encoders and audio is
encoded using Dolby Digital 2.0 AC3 encoding. The units will encode, and packetize incoming signals and
then multiplex them together so that they can be digitally QAM modulated in preparation for final RF agile
up-conversion.
QRF5000DQ
The QRF5000DQ contains a digital QAM tuner module, which can be configured to tune to any channel
within a standard cable lineup. Once tuned, the user is shown a list of services which are within the digital
channel. The users can than select which services to keep, and which services to remove. In conjunction
with the up to three installed encoders and external RF Notch Filter, the user can add local video to an
existing digital QAM. This allows for maximum bandwidth allocation and provides a path for head end
communications to reach a digital QAM tuner in the case where set top boxes are not used. This is
important for applications where such signals as E.A.S are required.

DC Power, FAN and I/O
The unit is powered by 9V DC @ 4A power supply.
Four port I/O connector is not used at the moment.
Audio Inputs
Each encoder supports two channels of audio. A dual vertical stacked RCA connector is available.
Video Inputs
Each encoder supports one video input and can be either an S-Video or Composite video input. A
BNC connector is available for the composite video and an S-Video DIN connector is available for
the S-Video input.
ASI Input
To allow for channel expansion an MPTS ASI input is available on all QRF products. . A BNC
connector is available for the MPTS ASI input.
ASI Output
The QRF5000 transmits an ASI output which is the multiplexed MPTS ASI stream containing the
encoders, ASI and RF inputs.
RF Input
The QRF5000 receives its input via a 75Ω F-Connector. This should be connected to the RF cable
feed for tuning and decoding of digital QAM signals.
RF Output
The QRF5000 transmits an RF output which is the QAM modulated MPTS ASI stream upconverted to the user’s desired frequency.

Menu Navigation
Menu items are highlighted using the Up and Down keys and selected using the right or Enter keys.
The Left key will back out of a menu into the previous menu and the Plus and Minus keys are used
to increment and decrement digits. The Enter key must be depressed in order to save a selection or
setting.
Selecting and Saving Settings
When a selection is confirmed using the Enter key a “Saving Changes” message will appear.
Loading Defaults
The original factory settings can be loaded by navigating to the System | Load Defaults menu and
selecting Yes.
All settings are stored in FLASH and will be remembered after power cycles.
Controlling the unit via Ethernet
The QRF5000 series can easily be controlled remotely via an Ethernet
connection using Radiant Communications RepManager Software.
The first task is to discover the unit(s).
QRF5000 RevG2 Series Installation and Operation Manual
Page 10
Once the units are discovered, they can be easily configured, upgraded or restarted. If the units are
discoverable, but not on the same subnet, you will prompted with the ability to temporarily change the units IP so
that you can communicate with it.
Configuring the unit
After selecting the unit you wish to configure by highlighting the units IP, select the configure
button. If the password has been modified from the default ‘0000’, the following dialog box will appear.
After entering the proper password, you will see the following dialog box.

The tuner page allows you to easily add and remove program filters.
Updating Client Software
To update a QRF5000 series product, simply highlight the unit you wish to update, and select the
Upgrade option. You will be prompted for an upgrade file. (Contact Radiant Communications
Technical support for questions regarding unit upgrades)

Auto Match PIDs Procedure
The “Auto Matching PID’s“function from Radiant Communications is an easy way for the QRF
product family to add local video insertion without having to worry about potential PID conflicts.
The QRF can automatically assign PID values that match values from services in the incoming
QAM. These are normally services that are to be dropped and replaced with the local services.

Discover the QRF5000
The units are shipped from the factory with a DHCP enabled. When discovered with the
GUI, the units will have 169.x.x.x IPs.
o
Highlight the unit and click Network Settings. This will set the device to a temporary IP
address. This temporary IP is intended to allow communication with the device if it is not presently
on the same subnet as the PC.
o
o
Click ‘Discover’ than highlight the unit with the temporary IP and click Configure.
Under the ‘General’ tab, change the network settings. Uncheck DHCP and enter the new
static IP, Subnet and Gateway. Click Save and Yes on the new window to confirm the changes, and
reset of the unit.

Program the tuner
If not already open, launch the configuration editor for the QRF in question, by highlighting
the unit in the REP Manager and hitting ‘Configure’.
o
Under the Tuner tab, enter the frequency and QAM mode of the incoming QAM channel
that you wish to drop and replace.
o
o
Highlight the program(s) that you wish to filter and press the arrow button.
The left table shows ALL services found at this frequency. The right table shows services
that are being filtered.

Cable Modem Setup Procedure
The QRF5000 series can easily be controlled remotely via an Ethernet connection using Radiant
Communications RepManager software.
Successful Ethernet connection could be established by following the steps below. This procedure
can be done on all QRF5000 Series units.

Install the Radiant Communications RepManager software on the management PC. The
latest version of the software could be obtained from the CD included with the unit or by
downloading it from http://support.rccny.com/qrf .

Connect the QRF-5000W Series unit to the cable modem using Ethernet RJ-45 cable. The
network port is located on the front panel of the QRF-5000W unit.

Configuration:

Configuration using the controls on the front panel of the unit.
The units are shipped from the factory with a DHCP enabled. If your network doesn’t contain a
working DHCP server, a static IP within the subnet must be assigned to the unit.
Below is the menu tree structure of the network parameters. All defaults are in bold or in
parenthesis:
o System
 Network
o IP Mode
 Static
 DHCP
o Static IP
 Set Static IP using left, right, and +/- keys
o Status
 Displays the IP Configuration
o Advanced
 DHCP Fallback
 Set the DHCP Fallback Address
o Configuration using the RepManager Software.

Discover the QRF
The units are shipped from the factory with a DHCP enabled. When
discovered with the GUI, the units will have 169.x.x.x IPs.
Highlight the unit and click Network Settings. This will set the device to a temporary IP
address. This temporary IP is intended to allow communication with the device if it is not
presently on the same subnet as the PC.

Click ‘Discover’ than highlight the unit with the temporary IP and click Configure.

Under the ‘General’ tab, change the network settings. Uncheck DHCP and enter the new
static IP, Subnet and Gateway. Click Save and Yes on the new window to confirm the
changes, and reset of the unit.
The communication port used by Radiant Communications RepManager Software is UDP - 2000. This
port must open throughout your network.
