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
snap. The new compact enclosure allows mounting of two tuners in a single rack space.
The integral HD-SDI output allows inclusion of 708/608 captioning, choice of AES stereo or AC-3 audio, and
scaled output set to a constant 1080i, 720p, or 480i resolution.
A universal TV tuner, the ATSC+SDI can receive both analog and digital channels, in ATSC, NTSC, and clear
QAM formats. Using an optional RF switcher, the tuner can switch between Antenna and Cable feeds.
Tunes analog and digital channels in ATSC, NTSC, and clear QAM formats
Always-active HD-SDI, Component, and composite video, as well as stereo, and digital coax and
TOSlink optical audio ports

Quick Setup
Tuner Setup –Front-panel Quick Setup
RGB or Component out
Click the SETUP button, use Up or Down to HD Output menu, use
Left or Right to choose input, press SELECT to choose.
HD Resolution
Go to the next menu down, and cycle through the list of resolutions.
Press SELECT to choose.
Air or Cable Tuning
Go to the next menu and select CATV, Air, IRC, HRC, or CATV Auto.
Press SELECT to choose. IRC has the same channel map as
standard CATV, except for 5 and 6. The HRC channel map uses
completely different frequencies than the others. CABLE AUTO looks
at the first few channels to determine the right format. If there are
no channels between 2 and 6, you many have to set the tuning
mode manually.
Select Scan Mode
Page down a number of menus to the Scan Mode menu. The left or
Right keys will select several options
Analog+Digital (standard full scan)
Digital –Delete Analog (scan for digital, delete any analog
channels)
Digital –Keep Analog (scan for digital, but keep all analog channels)
Analog –Delete Digital (scan for analog, delete any digital
channels)
Analog –Keep Digital (scan for analog, but keep all digital channels)
Once you do the next step, scan from the front-panel menu, the
tuner will always scan this way from the panel or on-screen menu –
until you change the mode later on.
Channel Scan
The next menu starts the Channel Scan, just press SELECT to start
scanning. You can watch the scan progress from a pop-up window
on the video outputs from the tuner. You can watch the scan
process if the output of the tuner is fed to a display. A Cable
analog/digital scan will take 7 minutes, only digital 6 minutes (the
analog scan is faster).
Channel Tuning –On-Screen menus
Scan Channels
Press Blue MENU button, Channel, Auto Scan, then scan mode -
usually Cable Auto for cable, Air for off-air channels. The tuner will
automatically delete encrypted Cable programs. Wait for the tuner
to finish analog scanning, then it will re-scan channels for digital.
Press SELECT when tuning analog to skip to scanning for only digital
channels.
Audio
Press Blue MENU button, Setup, Digital Output, then Dolby, PCM
(Stereo AES for SDI) or PCM Variable. If you get a “motorboat”
sound for digital sound, switch to PCM.
Screen
Press Blue MENU button, Setup, Screen Format and select between
4:3, 16:9 and Zoom options. Stores two different options for digital
and analog channels. Options vary in analog and digital, and the
channel itself may restrict your options. You can also use the RATIO
button on your remote.

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.

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.
