2 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.

5 DC Power, FAN and I/O The unit is powered by 9V 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. QRF5000 RevG2 Series Installation and Operation Manual Page 4

15 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 o 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 Click Discover than highlight the unit with the temporary IP and click Configure. o 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.

19 Auto match PID s. o Go back to the REP MANAGER main screen, and highlight the unit that was just configured. o From the Device Menu, click Auto Match PIDs. o Click the Set Using Active Services link. This will open another dialog box which will contain a drop down list of all the services found on the tuner. Select the Encoder1 tab, and also the service which you wish to drop. Click Match and all PID s for this service will be set to that of the incoming stream. o o Repeat for Encoder 2, make sure to select Encoder2 tabs when doing so. Click Save to Save and apply all settings. QRF5000 RevG2 Series Installation and Operation Manual Page 18

20 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 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.
