Overview CR QMOD™ technology is opening the door to new HDTV applications. Create your own on-site HDTV broadband distribution system using a variety HD, SD, and AV sources with the Contemporary Research QMOD-SDI HDTV Modulator. No matrix routers or IP resources required, just tune in with standard displays or CR HDTV tuners.

Front Panel Setup There are a number of parameters that can be set by front-panel Setup commands. In normal operation the Up/Down arrows select channels, and the Left/Right arrows adjust volume.
In most applications, the basic settings on the previous page will work fine with all displays. Of course, there are exceptions to every rule that often arise with older displays with archaic firmware, which is why we offer a variety of encoder options and settings. A few examples include: Older LG sets need to see the MPEG stream encoded at 18 Mbps (19.4 Mbps total). Newer displays don’t need channel data, older sets need to see the CVCT data table.
Tips & Troubleshooting Common Symptoms Symptom QMOD constantly resets – analog inputs QMOD SDI switches to background color during setup or occasionally. QMOD channel tunes fine connected directly to a TV, but not when combined with in-house RF system. QMOD channel is Green Contemporary Research Solutions Usually, the encoder is resetting because the input video isn’t set to a correct HDTV resolution or frequency. Check if your QMOD has V 5.1 or higher firmware, if not, go to www.crwww.com/downloads.
General Symptoms and Solutions Symptoms Solutions Status Codes Appears on QMOD front panel display “*” appears at end of bottom line when not locked to SDI signal “?” appears when SDI is locked but at incorrect resolution or Hz “*” appears at end of top line when QMOD is using a virtual channel. “R” appears at top left of front panel display, notes the encoder is resetting: Usually the VGA or scaler output is not set to 1080i/720p 59.
Digital signage presentation almost always require a scaler to format the output for HDTV displays Use VGA to Component or SDI scaler, set to 720p/1080i, 59.94 Hz Most HDTV displays overscan video, underscan video to fit to displays Design signage with safe area Use Up, down, left, right scaler adjustments to fit Using a signal generator or test graphic, adjust quality with Sync TrigLev setting 1-4.
RS-232 Control Protocol Overview The QMOD-SDI full duplex RS-232 enables a system programmer to control all functions as well as monitor status. All commands are sent as ASCII strings. No delays between characters or commands are required, as data is interrupt driven and buffered. One QMOD-SDI may be daisy-chained together with a CR 232-series tuner from a single RS-232 port. The QMOD-SDI is pre-set to Unit 1, and the tuner would be set to Unit 2.

Characters received will be re-transmitted. Example: ‘>EN’ Characters received will be re-transmitted. Returns the product model number and software version.
RS-232 Cable Connections Single QMOD-SDI RS-232 wiring for control or programming should only use pins 2, 3, 5. Cables with all pins wired can lock out front-panel programming and data communication (Pins 4 and 9 are inputs). QMOD-SDI Daisy-Chain One QMOD-SDI and 232-series tuner can be controlled from one RS-232 control port. The QMOD-SDI will be Unit 1, and the 232-series tuner will be set to Unit 2.
Rack Mounting Three options are available for rack-mounting QMOD modulators RK2 Dual Rack Kit with Tie Bar Mounting New QMOD and QCA enclosures have a slot in the bottom middle of the case. This will accept a tie bar that will lock the two enclosures together without taking the cases apart . 1. 2. 3. 4. Check that your enclosures have the tie bar slot. Slide the included tie bar into the side of one unit and attach with the included screws.
