FAQ
Tuning Cable Channels
The 232-ATSC 4 will skip encrypted channels automatically when you activate a channel scan.
You can skip scanning analog channels by pressing Select after you start the scan.
Typically, the digital channels will not use the same Guide numbers as a cable box.
If you can’t select channels, make sure that the channels have been scanned.
RGB/Component Video
Analog HD is output on either the RGBHV (VGA) or Component output. Use the front-panel menu to select
the desired output.
There can be “fluttery” lines at the top of the analog channel – this is closed captioning data.
Go to the Overscan menu and increase the value.
HDMI
HDCP is always off – not required for non-encrypted programs
If a monitor has issues with current resolution, 1080p/60 works best for newer models.
DVI
DVI compatibility is normally supported; you can manually select DVI from the HDMI-DVI menu.
Composite Video
Press the RATIO button on the IR remote to select the desired format for NTSC video
The onscreen menu also has Screen Format settings, generally only used when tuning an analog channel
Audio
Volume won’t affect digital audio in AC-3 or PCM modes PCM Variable supports level control
If there is no audio, make sure the volume is all the way up (and not muted).
Digital audio is sent as Consumer format, the Digital Audio menu can change to Professional format
A “motorboat” sound means the source does not support AC-3, change to PCM.
Power/AV
If the LCD shows only Power On, call CR Support for solutions
If you can’t change volume or channels and there is no video, first try an alternate power supply, call
Support if needed.
The tuner will display “Voltage Low” if the power supply is failing or low. Press SETUP, go to the Firmware
menu, and then press the Right arrow several times to see the exact voltage. There is a “Voltage High”
warning if the supply is significantly higher than 12 VDC.
IR Control
There can be interference from room fluorescent lights. Hold down SELECT on the remote. Pressing 4
selects normal 38 KHz IR, pressing 9 selects 57 KHz IR.
Check the front-panel IR Receive menu to see if it is turned on or off.
If there is significant IR interference, an IR-RXC Remote Sensor may be required, and cover the front-panel
IR sensor to reduce interference
Captioning
If the tuner is feeding a digital channel modulator, use Composite video to send captioning data.
If the site wants to see captioning on all TVs, turn the feature on in the tuner.
S37 Installation
See Support Blog on Windows 8-10 settings for S37 installation.
Front-Panel Button Sequences
• Pressing Up and Down keys toggles air/cable tuning
• Pressing Left and Right keys toggles mute on/off
• If the Setup key is locked out, pressing Setup and the Right key will unlock setup until the tuner resets, and turns the tuner on if it is off
(even if the Power button is locked)
• Press Power and Up together when at Setup:Firmware menu to reset to default settings
• Remove power, hold Up and Down together, repower, then release to force S37 firmware load

HD2-RC IR Remote
The HD2-RC IR Remote included with the 232-ATSC 4 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 4 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 a download.
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
• Enter selects menu choice
Special Functions
• CC steps through available closed-captioning options
• Audio selects audio and SAP modes
• Signal displays channel signal level
• Ratio steps through aspect ratios, options depend on channel and output
types
• Info launches on-screen information window
• A/C selects Air or Cable tuning
• 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.
Pressing Select and 4 together outputs 38 KHz IR, Select and 9 outputs 57 KHz IR,
useful when there is IR interference.
