- Purple (default)
- Green
QAM Type
Today, most displays are set to tune 256 QAM. If a site has some very old displays, they
might only be able to tune in channels set to 64 QAM. Continuous Wave is often used to test
the channel with a meter.
- 64

Menu
Parameters
Quality Settings
These adjust the overall quality of encoding
Trig Lev
This is a cable compensation setting that adjusts output for different Component or RGBHV
cables. To see the difference in quality you’ll need a test chart from a Sencore or other
HDTV signal generator. Adjust using the same cable you’ll use for the installation.
The settings are 1-4, with 2 as the default.
Video Bitrate
This adjusts the quality of the encoded video, in mbits per second. For typical HD
satellite/cable, 18 the best solution, as the receiver’s video output rarely exceeds 12 mbps,
and old and new display tuners will tune that in. For very good HD video sources, such as
from HDTV studio feeds on SDI or Component, 25 may produce visible improvement. Note
that some older display tuners don’t expect to see a video stream larger than 19.4, and you
may need to go down to 18 for those sets. The lower settings are for special applications and
are rarely used in normal systems.
- 11, 13, 15, 18 (default ) , 25
MPEG Metadata
When you work with a variety of displays, old and new, you may need to change the settings
below to assure all tune the channels equally. The settings below select the type of
metadata included in the MPEG video stream.
PMT Type
Program Map Table Presets. This setting includes four presets that include various minor data
we’ve used in past installations. In most cases, use the default Type 0.
0-3 (0 is default)
CVCT
Default Cable Virtual Channel Table
On - Turns on virtual channel and short name in MPEG stream, if present
Changes QMOD display Channel to virtual channel
An “*” will appear at the end of the channel if it is virtual
Off - Turns off CVCT data, changes display back to Channel: <Physical>.1
Tip: Turn off CVCT when creating virtual channel, then turn on when complete. TVs will need
to re-scan to find the channel.

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.
Some displays want to see certain PMT data, while most ignore almost all values.

Tips & Troubleshooting
Symptom
Solutions
QMOD channel tunes fine
connected directly to a TV, but
not when combined with in-house
RF system.
There are several classic caused for this. When you insert the channel into the
house system, there are added interference and level issues.
If you’re mixing with an incoming cable feed, assume there are no
“empty” channels. Usually, your QMOD channel conflicts with an existing
cable channel. Read the QMOD Integration Guide to learn how to use
blocking filters to screen out the offending cable channel.
When your combining the QMOD channel with an existing system, it has
to be set to the right RF level. For example, if the analog channels are
running at 55 dBmV, you’ll need an RF amplifier to raise the QMOD 29
dBmV out to at least 45 dBmV.
Use a digital RF meter.
QMOD channel is Green
Also could be Orange or Purple. This is the color background the QMOD
inserts when there is no or improper video input. This means that the
QMOD is working, the channel is tuned correctly, but there is an input
problem. It’s also good test signal when you set up QMODs before the
sources are connected. You can also feed audio to the QMOD and test
that as well.
Patterned green over RGBHV/YPbPr image. Usually caused by extreme H
or V image shrink. When Horizontal or Vertical is active (white line in
middle of H or V bottom line, press the Up button and click the SELECT
button. That will reset values for that resolution to default.

General Symptoms and Solutions
Symptoms
Solutions
Status Codes
Appears on QMOD front panel display
Encoder Error
“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 59.94 Hz – Use
the Measure menu to see the H and V frequency
Press the left and right arrows together to reset the QMOD
If neither fixes the condition, call CR Support
“X” appears, notes there is no communication with the encoder
If you check the Firmware menu, the last 4 characters might be “0000”
instead of 02E5 or 02E7
Call CR Support
Video signal
“V” Appears when the QMOD can’t see a video signal – often when unit is
set to Component and the source is RGBHV.
No FPGA firmware (QAM)
“xxxxxxx” appears when you use the firmware loader, or press the right
arrow when you view the firmware version on the QMOD.
V X.X = Control Firmware
02A2 = Encoder Firmware
J83B and following = FPGA firmware
“xxxxxxx” means that the FPGA firmware is incomplete or corrupted.
Re-install firmware or call CR Support if you can’t update.
Green screen
That’s good news – it means the TV is receiving the channel from the QMOD. The
green (or blue, purple) background means that there is no video input.
Black Screen or No Signal
Reset the QMOD by pressing the Left and Right arrows together.
Component
No video – check input wiring and settings
Tip – you can use RCA to HD15 cable to connect YPbPr
Wrong vertical frequency, source must output 720p 59.94 Hz , 1080i 29.97
Press left and right panel buttons together to reset encoding
PC VGA
QMOD screen states No Signal or Incorrect SIG
DVD
Check cables and input setting
Blue-Ray players only output 480p/480i on Component, requires HDMI to
Component interface by others.
Tuning Issues
Displays not finding channel in scanning, or have problems locking on to channel.
Update QMOD Firmware
Check CRWWW.COM for the latest firmware, download, and install.
Update Settings
The update won’t affect your current settings. Typical settings are Vid Bitrate 18,
CVCT On, QAM 256, PMT 0.
Test offline
Test a sample TV connected directly to the QMOD to eliminate problems in the RF
system.
Can’t tune channel
This is generally a result of a problem in the “digital handshake” between the
modulator and the TV’s digital tuner. Modern sets such as LG accept a wide range
of settings in the channel and metadata.
Old TV – try 64 QAM, also note that many old TVs have very poor tuning
capabilities. 64 QAM setting has the effect of raising level about DB –
helpful if RF level is very low.
Old TV Firmware- TV brands update their firmware as well.
If the display tunes offline, then there are problems in merging the
QMOD with the RF system.
Call CR Support
No audio
Check audio inputs and wiring
Set source digital source output to PCM
Some Sharp displays lack the standard QAM codec to play MPEG1 stereo, those
models should be avoided for commercial sites.

RS-232 Control Protocol
Overview
The QMOD-HD 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-HD may be daisy-chained together with a CR 232-series tuner from a single RS-232 port. The
QMOD-HD is pre-set to Unit 1, and the tuner would be set to Unit 2.
Communications parameters (Front Panel Mode 1) are 300 to 19200 baud, 8 data bits, No parity, and 1 stop
bit. Factory default is 9600 baud, Unit#1.
All settings are saved to NVRAM in the QMOD-HD.
The QMOD will accept non-standard RS-232 control such as voltage that swings from 0 to +5 VDC,
commonly found when IR ports are used to send RS-232 commands.
General protocol specifications
Characters in command strings to the QMOD-HD are common ASCII keyboard characters.
Command strings sent to the QMOD-HD begin with the ASCII > (greater than symbol) as an 'Attention'
character and end with carriage return - ASCII CR, Hex $0D, or keyboard Enter - as an 'End-of-command'
character.
Responses from the QMOD-HD begin with the ASCII < (less than symbol) as an 'Attention' character and
end with a carriage return followed by line feed an ASCII LF or Hex $0A as 'End-of-command' characters.
A carriage return is required at the end of each command and is assumed in all examples.
Attention Single character (>) starts the string
Unit# The Unit# is expressed as an ASCII 0-9 when used in multiple tuner applications.
To address all units, use a Unit # of 0 (Zero)
No unit number will default to Unit#1
Command A two-character command
Parameters Added attributes to some commands
Return A carriage return ends the command string, you may use ASCII CR, Hex $0D, or keyboard
‘Enter’ in programming. For simplicity, the programming examples in the manual will not
show the ‘CR’ – so remember, you’ll need to add it in your control code.
Command and Status Response
Commands can be sent back to back at any time without any delay. To allow for rapid, multiple commands,
status responses are intentionally delayed by about 125mS, sending the most current status in response to
control commands or user actions.
