Setup Notes

Tuning Cable Channels

The 232-ATSC 4K will skip encrypted channels automacally when a channel scan is iniated. Scanning analog channels may be skipped by pressing SELECT

aer the scan has started. Typically, the digital channels will not use the same Guide numbers as a cable box.

RGB/Component Video

Analog HD output is available on either the RGBHV (VGA) or Component jacks. Use the front-panel menu to select the desired output mode. When selected,

YPbPr is also available on the HD15 connector.

DVI

DVI compability is normally supported. Forced DVI may be manually selected from the HDMI-DVI menu. DVI does not hot-patch, so the tuner may need to

be rebooted aer DVI mode is selected.

Audio

The volume sengs do not aect digital audio in AC-3 or PCM modes. PCM Variable supports volume control. The analog audio outputs always follow the

volume sengs. 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 uorescent lights can cause problems with IR remote operaon. If this occurs, the frequency of the IR can be changed. Hold

Select on the remote 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.

• Check the front-panel menu to see if IR Receive is turned on or o.

• If there is signicant IR interference, an IR-RXC Remote Sensor may be required. Cover the front-panel IR sensor to reduce interference.

Caponing

Line 21 caponing data is available on the Composite video output. If the tuner is feeding a digital encoder or encoder/modulator, use Composite video to

send caponing data. On-screen caponing may be enabled from the on-screen menu, IR remote, or RS-232 commands.

Web Pages

Control Page Sengs Page

The 232-ATSC 4K includes Web pages accessible by any browser over IP. Open a web browser and type in the tuner’s IP address in the address bar. The tuner’s

IP address may be found by holding down the SETUP buon. The Control Page features a full array of control opons with interacve status feedback, including

channel name, program name, and the nave resoluon of the program. The Sengs Page can change any aspects of tuner setup and operaon. The name of

the tuner can be changed by clicking on the name at the top of the page.

HD2-RC IR Remote

The HD2-RC IR Remote included with the 232-ATSC 4K can be used to setup the tuner and for daily operaon. All of the funcons on the remote have equiva-

lent commands in RS-232, Ethernet, and Wired IR formats. In addion, the 232-ATSC 4K front panel buons are available for Power, Channel, Volume, Menu,

and Select. The tuner will display a “^” symbol in the upper right corner of the front panel display when an IR command is received.

Power

Turns the tuner on and o.

Volume Control

Use the Vol+, Vol- and Mute buons to control the volume.

Channel Selecon

Two-part digital channels are accessed using XX-1 (or -2, -3, etc.).

Single-part digital and analog channels are accessed using XX.

Ch+, Ch- and PrevCh can be used to access and recall channels.

Menu Operaon

Press Menu to access the on-screen menus.

• Use the direconal Arrows, Select and Exit to navigate the menus.

• List brings up the Favorite Channels menu.

• Exit closes the on-screen menu.

• Enter selects the menu choice.

Special Funcons

• CC steps through available closed-caponing opons.

• Audio selects audio and SAP modes.

• Signal displays channel signal level.

• Rao steps through aspect raos opons.

• Info launches the on-screen informaon window.

• A/C selects Air or Cable tuning.

• Fav displays a list of favorite channels.

• Guide displays the on-screen guide. When the guide is displayed, pressing Info displays the

program descripon.

Features of many of the Special Funcon commands depend on whether the current channel is

analog or digital.

Hold the Select buon and press “9” to set the IR frequency to 57 KHz. Hold the Select buon

and press “4” to set the IR to the normal 38 KHz frequency.

RS-232/Telnet/UDP Control Protocol

The 232-ATSC 4K full duplex RS-232/Telnet protocol enables a system programmer to control all TV Tuner funcons 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 buered.

Up to 9 232-ATSC 4K units may be cabled together and addressed for individual control from a single RS-232 port. Each 232-ATSC 4K is assigned a unique unit

number.

Communicaons parameters are 1200 to 230,400 baud, 8 data bits, No parity, and 1 stop bit. Factory default is 9600 baud. All sengs are saved to NVRAM in

the 232-ATSC 4K tuner. 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.

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 (xed) with status feedback on port

31932. Port 31932 is disabled by default, send “>UO” command (UF turns UDP status feedback o) or set with front-panel menu. See our Support Blog Tesng

232-ATSC Series UDP Control to learn more about UDP control.

General Protocol Specicaons

Characters in command strings to the 232-ATSC 4K are common ASCII keyboard characters.

Command strings sent to the 232-ATSC 4K begin with the ASCII > (greater than symbol) as an ‘Aenon’ character and end with carriage return - ASCII CR, Hex

$0D, or keyboard Enter - as an ‘End-of-command’ character.

Responses from the 232-ATSC 4K begin with the ASCII < (less than symbol) as an ‘Aenon’ 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

[Aenon] (Unit#) [Command] (Parameters) [Return]

Aenon Single character (>) starts the string

Unit# The Unit# is expressed as an ASCII 0-9 when used in mulple tuner applicaons.

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 aributes 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 pro-

gramming examples in the manual will not show the ‘CR’.

Command and Status Response

Commands can be sent back-to-back at any me without any delay. To allow for rapid, mulple commands, status responses are intenonally delayed by

about 125mS, sending the most current status in response to control commands or user acons.
