Contemporary Research 3 ATSC+SDI HDTV Tuner
Overview
The ATSC+SDI is the first HDTV Tuner that features an onboard HD-SDI port. A professional HDTV tuner,
the ATSC+SDI is controllable via RS-232, IP, and IR commands. An onboard Web page enables remote Web
control. A new menu-driven display simplifies setup, and a front-panel USB port makes firmware updates a

Contemporary Research 9 ATSC+SDI HDTV Tuner
Firmware Update
System Firmware
The system firmware (S37) is the most common type of update. It’s a small file and doesn’t take too long to
update.
In the 232-ATSC+1, you won’t need an RS-232 port. Just download the .zip file from our website, open the
ZIP folder, then copy or drag the file to a pop-up file window, just as if the tuner was a memory stick.
Download the firmware from the 232-ATSC+1 Product page
oBrowse to www.crwww.com
oSelect Products, then choose the 232-ATSC+1
oSelect the Downloads tab and download the latest firmware
oOpen the ZIP folder
Connect your PC to the USB port of the 232-ATSC+1.
Select the red Setup button on the ATSC front panel, then go to the Setup: Firmware setting
Click Setup and Power together –a file folder will open on your desktop and the front panel of the
tuner will display Firmware Loader
Copy and paste or drag the file into the folder
The front panel will show File Loading, then Copying Image.
When the process is complete, the display will change to Firmware Loader
Press the Left to exit the mode, no need to exit Setup or reset power
HD Load Processor Firmware
This firmware process updates the HD processor in the 232-ATSC+SDI; it’s a much larger file and uses a
different set of steps for updating.
Download the new version of HD Load from the website. The .exe file will save the firmware to a
folder in C:/CR Temp when you click OK on the pop-up window.
Connect an RS-232 null modem cable from your Windows PC to the RS-232 input on the back of the
tuner. The data rate of the update is too fast to use the USB connection on the front of the tuner.
Remove the 12 VDC cable from the back of the tuner.
Go to the CR Temp folder and run HDLOAD.exe app.
Select the COM port you’re using from the pull-down list at Connection. Don’t select Enable
Dynamic 2X Speed as an option. On some PCs, you may need to go to Control
Panel/System/Hardware manager, right-click the COM port, and select Update Driver.
Keep the default settings, Model=TL9xx, Data Type=Application
Under the File option, browse to select the HD_Vxxxx.raw file.
Click the Connect button below Configuration.
Click the Start button to begin the download process
Hold down both Volume (Left + Right) buttons and connect DC power. The front-panel display
will flash and show HD LOAD, to show it is in the Processor Download mode.
The Download Progress bar and Message box will keep you up to date on progress. If you have
difficulty downloading, try updating the driver for the USB adapter, use a different adapter, or retry
the process a few times.
The Message text will tell you when the process is complete. Close HD Loader reset DC power to the
tuner.
You can check the firmware update version by selecting SETUP, click Up to show the
Setup:Firmware menu, press the Right key twice to see the HD version.
Contemporary Research 10 ATSC+SDI HDTV Tuner
Troubleshooting
TUNING CABLE CHANNELS
Tip: The 232-ATSC+SDI will skip encrypted channels automatically when you activate a channel scan
Tip: You can skip scanning analog channels by pressing Select after you start the scan.
Symptom: Channel ID is in XX-XX form, not cable box Guide form
Cable boxes translate the actual channel #s into a virtual Channel Guide, using channels 2 –900, or
more.
The actual (physical) channels have IDs in XXX-XX form, just like off-air channels. Non-cable HDTV
tuners like the ATSC or LCD TVs don’t provide Guide features, so the channels will be displayed in
their native, physical major-minor channel form.
Some cable companies are using a useful format –the cable channels will have a single virtual
channel that is the same as the Guide, and local TV channels may use the same virtual major-minor
listing as the off-air channel.
Some cable franchisees have a listing by physical channel, many do not. You can press the INFO
button on the HD2-RC remote to view the channel name.
POWER/ NO VIDEO or AUDIO
Symptom: Tuner cycles power and LEDs
Power supply is not providing enough amps of power (1 A or more). If you’re replacing an old CR analog
tuner, the old power supply is 500 mA, and will cause the “power cycle” effect. Use the power supply that
came with the tuner, or call to order a new one. Voltage range should be 11-14 VDC.
Symptom: Tuner appears to be on, channel display is lit, but unresponsive, no video/audio out
When the tuner turns on, it will display Voltage Low or Voltage High if there is power problem.
Go to the Setup: Firmware menu and click the Right key to display the exact voltage.
Contemporary Research 11 ATSC+SDI HDTV Tuner
HDMI
Symptom: Scan or “fluttery” lines at top of video, usually on an analog channel
Use the Overscan menu to crop the video a bit. What you’re seeing is the data (captioning) portion of the
video. Adding a bit more overscan will eliminate the lines at the top.
Composite Video
Symptom: Composite video out has small image in 16:9 setting, analog channels
For a 4:3 set, tune to an analog channel and press RATIO on the remote or Setup: Screen Format
on onscreen menu to set to 16:9. Image will fill left to right, you’ll always have a black band top and
bottom.
Set to 4:3 if you’re only feeding video to 4:3 TVs.
Set output ratio on a digital channel as well - this a different setting than for analog channels.
If the tuner is used for 16:9 displays and analog TVs, choose the best setting for the widescreen,
and the NTSC will have to be a compromise. Most of the time, setting the RATIO while tuned to an
analog channel and again for a digital channel will provide the best result.
IR Control
Symptom: IR remote won’t control tuner
Hold down IR remote Select, press 9, and release both. Front-panel setting should be IR On. In addition,
check if the remote works when the lights are off. Some energy-saving fluorescent lights produce
interference at our IR frequency (57 Hz). Try to cover the IR sensor so the lights don’t affect operation, or
add the IR-RXC External IR Sensor. It’s easier to hide and tilt the sensor to help with reception, and you can
try Select and 4 to use the lower IR frequency (the RXC has both types of sensors).
Captioning on Video Outputs
Symptom: Video out does not include captioning data
The 232-ATSC+SDI provides on-screen captioning on all ports, the SDI port supports 608/708 captioning,
and the Composite video includes Line 21 data. The Component port does not output captioning data, not
supported in the Component standard.
Contemporary Research 12 ATSC+SDI HDTV Tuner
HD2-RC IR Remote
The HD2-RC IR Remote included with the 232-ATSC+SDI can be used to setup the tuner and for daily
operation. All of the functions on the remote have equivalent commands in RS-232, Ethernet, and Wired IR
formats. In addition, the 232-ATSC+ front panel buttons can perform Power, Channel, and Volume control.
Power
Turns tuner on and off. Discrete on and off IR commands are
available as well.
Volume Control
Use the Vol+, Vol- and Mute buttons.
Channel Selection
The key change in digital tuning is the need to add a dash (-) and
number after the traditional channel number. Analog channels are
accessed using XX-0, digital channels using XX-1 (or -2, -3, etc).
Ch+, Ch- and PrevCh can be used to access and recall channels.
Menu Operation
Press Menu to access the on-screen menus.
Use the directional Arrows, Select and Exit to navigate the
menus.
List displays the list of all channels, arrow keys add/remove
channels, set Favorite Channel list
Exit steps backwards out of menus

Fav Displays list of favorite channels
Guide displays on-screen Guide
Features of many of the Special Function commands depend on
whether the current channel is analog or digital.
Tip: The output rules behave differently for digital and analog
channels. When you set up the tuner, use the RATIO button to set
image output for a digital channel, then tune to an analog channel
and set that to 16:9 or 4:3. The same rule applies to the
Menu/Setup/Screen Format menus. Set for analog and digital.

The 232-ATSC+SDI full duplex RS-232 enables a system programmer to control all TV Tuner functions as
well as monitor TV Tuner status. All commands are sent as ASCII strings. No delays between characters or
commands are required, as data is interrupt driven and buffered.
The 3 status groups are: Channel/Source Select, Audio Levels/Mode and Front Panel. The Power button-
function status from the 232-ATSC+ front panel has been grouped with the Channel/Source for simplicity in
the most common modes of operation. Each of the groups has one ASCII status response string containing
all of the status data for that group. The current status string of a group is sent from the 232-ATSC+
whenever a valid command for that group is received by the 232-ATSC+ RS-232 port or front panel. A
group's status may be requested at any time via the RS-232 port. Status of all 3 groups is sent at power up.
The format of each group's status response string remains the same always.
Up to 9 232-ATSC+SDI units may be cabled together and addressed for individual control from a single RS-
232 port. Each 232-ATSC+SDI is assigned a unique unit code.
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 232-ATSC.
The tuner 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 232-ATSC+ are common ASCII keyboard characters.
Command strings sent to the 232-ATSC+ 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 232-ATSC+ 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.
Command String Structure
[Attention] (Unit#) [Command] (Parameters) [Return]
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.
