Contemporary Research QMOD-HD TV User Manual
Setting up a QMOD-HD/TV One Digital Signage System
Overview
Designed to broadcast the output of a digital signage player as a digital cable channel, a QMOD-HD/TV One
Scaler system includes the following components:
QMOD-HD HDTV Modulator
TV One 1T-C2-400 VGA Scaler
RK1-AC QMOD Rack Kit with Accessory Shelf
Components You Need
You’ll need a few parts essential to setup. Initially, you will set up using a direct RF connection to a TV. Once you
know the system is operating; then the system will feed a channel to the house system.
2 HD15 to HD15 monitor cables
1 Mini to Stereo RCA audio cable, if audio is needed
1 Flat-Panel TV with onboard HDTV tuner and a PC RGB connection
1 RF cable with “F” connectors
1 Digital Signage PC with HD15 output, ideally, pre-loaded with the client digital signage program
Ideally, use one of the site’s TVs to test the system before it’s inserted into the RF system. That’s the best
approach, but not always possible. That’s why it’s good to have one of your own, just in case.
If you have an Apple or WIN7 PC, you’ll likely need an EDID emulator for a 1980 x 1080 PC resolution. That’s
because both restrict resolution if the OS can’t see the EDID data from the scaler. Emulators include ConnectPro
VGA-EDID, Kramer VA-GAN, and Hall Research EM-EDID-HD-15.
Assembly
Attach the RK1-AC shelf and rack bracket to the QMOD-HD using the supplied black screws
Attach the included rubber feet to the TV One scaler
Mount the TV One C2-400 to the accessory shelf with the included two small Philips screws
Attach an HD15 monitor cable from the TV One PC/HD Scaled Out port to the RGB connection on the
QMOD-HD
Attach another HD15 monitor cable from the signage PC to the TV One PC/HD IN connection
Attach a mini to RCA stereo cable from the PC audio out to the RCA Stereo In on the QMOD-HD – if
audio is needed
Connect power to both units
Start PC and Signage App
Connect the PC to the TV (or its own monitor), start up the PC and run the signage app. You will use this video
for system setup. Remove the HD15 from the TV, and connect it to the TV One PC/HD IN connector.
QMOD Setup
Press the red SETUP button on the QMOD, and use the Up or Down arrows to access the setup menus. Choose
the desired option for each menu using the Right and Left arrow keys, then click SELECT to choose the option.
The QMOD menus will time-out after a period of time, so you may need to press SETUP a few times in the
process.
Setup: Resolution. Go to 720p then press SELECT. Generally, the TV One output is set to 720p when sent
from Contemporary Research. You can choose 1080i later on in the process if you desire.
Setup: Video Input. Go to RGBHV, then press SELECT.
Setup: Channel. This is normally set to 2.1 for testing. Once you’ve finished setup, you can set this to the
desired
Connect the RF output of the QMOD to the nearby TV, then use it’s remote to start a channel scan, using Cable
Standard or Cable Auto modes. By using channel 2-1 for testing, the channel should appear shortly in the onscreen channel list. You can exit scanning. At this point, you should see a color screen, which shows the QMODHD is operating, or the output of the PC if that has been connected and turned on.
