Installing the ATSC-mini
The slim profile of the ATSC-mini allows for mounting behind a flat panel display. The unit may be attached to the flat panel display with
user provided hook and loop fastener adhesive tape or attached to the wall using the mounting ears. The unit may also be set flat on a
suitable shelf or other stable flat surface.
Connect the HDMI output to a video display. Analog and S/PDIF digital audio outputs are available for connection to an amplifier or audio
system processor. Connect a coaxial cable from the CATV or antenna source to the Air/Cable input connector. The ATSC-mini will need to
be connected to an appropriate power source. Power may be supplied from the included PS-12-1.0 power supply or PoE from a compatible
network switch or PoE injector.
Following the completion of the physical installation of the ATSC-mini, a channel scan will need to be performed prior to viewing programs.
The channel scan may be initiated in the on-screen text A/V menu, the on-screen graphical menu, or via RS-232 or iCC-Net command.
ATSC-mini Control and Setup
The control and setup functions of the ATSC-mini may be accessible by:
•On-Screen graphical and text menus accessible from front panel or optional handheld IR remote
•RS-232 commands via rear panel DB-9 connector or Telnet
•On-board web pages
•One-way iCC-Net protocol commands delivered over the Ethernet through an ICE-HE-DXL display control center, an IP-DXL display
control center, Display Express Server PC, IC-Send software, or third-party control system

Setup Notes
Channel Scan
A channel scan will be required prior to initial use and subsequently following any changes to the received channel line-up. The channel
scan may be initiated in on-screen graphical menu, on-screen text menu or by RS-232 command. The Air or Cable scan mode should be
selected for the intended application prior to initiating the scan.
Tuning Cable Channels
The ATSC-mini will skip encrypted channels automatically during a channel scan. The scan of analog channels may be skipped by pressing
Select after the scan has started. Typically, the digital cable channels will not use the same Guide numbers as a cable box.
Air/Cable
The ATSC-mini has separate channel memories for air and cable channels. It is possible to toggle between the two channel memories. A
separate channel scan for each mode will be required.
The Air/Cable mode may be selected by:
•Press Menu + Down simultaneously on the front panel
•Tune Mode drop down menu on A/V web page
•Tune Mode selection in on-screen A/V text menu
•RS-232 command
The Air/Cable mode may be toggled by:
•A/C button on optional HD2-RC infrared remote control
•A/C button on Control web page
•Air/Cable button on A/V web page
•Press Menu + Down simultaneously on the front panel
•RS-232 command
HDMI/DVI
Compatibility with DVI displays is normally supported and automatically detected. Forced DVI or HDMI mode may be manually selected
from the HDMI-DVI menu setting.
Audio
The HDMI digital audio format may be selected as AC-3, PCM or PCM variable. The default setting is PCM Variable. The volume level
settings do not affect HDMI or S/PDIF digital audio in AC-3 or PCM modes. PCM Variable supports volume control on all audio outputs. The
analog audio output will always follow the volume control settings. If there is no audio, make sure the volume is all the way up (and not
muted). A “motorboat” sound means the display does not support AC-3, and the mode should be changed to PCM.
IR Control
•Interference from room fluorescent lights can cause problems with IR remote operation. If this occurs, the frequency of the IR may
be changed in the HD2-RC remote. Hold Select and press “9” to set the IR frequency at 57 KHz. Hold Select and press “4” to set the
IR to the normal 38 KHz frequency.
•If there is significant IR interference, an IR-RXD Remote Sensor may be required. Cover the front-panel IR sensor to reduce
interference.
•Disabling the IR sensor in the configuration settings will disable the front panel IR sensor and the rear panel IR In jack.
•The ATSC-mini will respond to a universal remote with the TV type set to Sharp.

HDMI CEC Display Control
HDMI CEC may be enabled for controlling display power. HDMI CEC sends standardized control commands over the HDMI cable. CEC
functionality is available in many TVs and displays designed for the consumer market. If control of the TV or display via HDMI CEC is desired,
it is important to check the TV or display’s documentation to determine if CEC is supported.
It is common for manufacturers to use their own unique term to refer to HDMI CEC. For example, Samsung refers to CEC as Anylink. LG
refers to it as SimpLink.
CEC may need to be enabled in the display. Some displays will automatically detect that a CEC supported device has been connected and
prompt for confirmation.
Although the industry strives for standardization relating to CEC, it is possible that some or all CEC control communication between the
ATSC-mini and connected display may not function depending on display make and model.
Restore Factory Default AV Settings
The video and audio default settings may be restored from the front panel in the event that a resolution is selected that is not supported by
the connected display. The default output resolution is 720p/59.94 as this is supported by a wide variety of display types.
The default AV settings may be restored by simultaneously pressing Menu and Select buttons on the front panel.
Restore Factory Default Settings
The unit may have the configuration restored to the factory default settings. The channel list is not changed as this data is stored in
separate memory.
The factory default settings may be restored using the on-screen text menu. Hold the Menu button to open the on-screen text menu.
Select the System menu and scroll to Firmware. Verify that the System firmware is displayed. Press Select to bring up the blinking cursor.
Simultaneously press Power and Up to restore the default settings.
An alternate method is available for restoring the factory default settings. This method does not require the on-screen menu and may be
useful if the selected video output resolution is not supported by the connected display. With the power disconnected, press and hold
Power and Up and reconnect power. Release the buttons after the power LED remains solid green.
On-Screen Text Menus
The on-screen text menus contain settings for communication and control as well as some A/V related settings. The menus may be
accessed by holding the Menu button on the front panel or handheld IR remote.

RS-232/Telnet/UDP Control Protocol
The ATSC-mini full duplex RS-232/Telnet protocol enables a system programmer to control all tuner functions, configure the tuner, and
monitor tuner status. All commands are sent as ASCII strings. No delays between characters or commands are required, as data is interrupt
driven and buffered.
Communications parameters are 1200 to 230,400 baud, 8 data bits, no parity, and 1 stop bit. Factory default is 9600 baud. All settings are
saved to NVRAM in the ATSC-mini tuner. The RS-232 port will accept non-standard control such as voltage that swings from 0 to +5 VDC,
commonly found when IR ports are used to send RS-232 commands.
The same commands can be sent over IP Telnet (up to two sessions) and via UDP to the tuner’s IP address to port 31931 (fixed). UDP
responses are disabled by default. Responses will be sent to port 31932 at the directed broadcast IP address of the tuner’s subnet. UDP
responses may be enabled in the on-screen text menu, web page Network Settings menu, or RS-232 command. See our Support Blog
Testing 232-ATSC Series UDP Control at https://contemporaryresearch.com/testing-232-atsc-udp-control/ to learn more about UDP control.
General Protocol Specifications
Characters in command strings to the ATSC-mini are common ASCII keyboard characters. Command strings sent to the ATSC-mini 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.
For commands that require a parameter value, the = (equals symbol) shown in the examples is optional.
Responses from the ATSC-mini begin with the ASCII < (less than symbol) as an ‘Attention’ character and end with a carriage return followed
by a line feed - ASCII LF or Hex $0A as an ‘End-of-command’ character.
A carriage return is required at the end of each command and is assumed in all examples.
Command String Structure
[Attention] [Command] (Parameters) [Return]
Attention Single character (>) starts the string
Command A two-character command
Parameters Added attributes to some commands
Return A carriage return ends the command string. ASCII CR, Hex $0D, or keyboard ‘Enter’ may be used in programming. For
simplicity, the programming examples in the manual will not show the ‘CR’.
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 125 mS, sending the most recent status in response to control commands or user actions.
String Example
The example below is a command for a channel change to 6-2 followed by the response string.
>TC=6-2
<1TU006Uxx1002x0
The status of a setting may be queried by omitting the = (equals symbol) and the parameter value. The following command queries the 63
step volume level.
>VL
<VL=62
