Troubleshooting

TUNING CABLE CHANNELS

Tip:

The 232-ATSC+1 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.

COMPONENT OR RGB VIDEO

Symptom: No Component or RGB Video

The RGB and Component outputs are switchable, and the tuner ships set to RGB. Use Front Panel Menus to switch the HD analog video to Component or RGB.

Some monitors and TVs can’t handle HD resolutions, only traditional VGA settings. Consult the display’s manual – a listing of resolutions is usually towards the back of the manual. Usually, those sets can only display 480i.

If the display can’t handle any setting, use HDMI or Component, or use a small scaler, such as the TV One C2-400, 1T-VS-624, or similar than can accept an HD RGB signal and convert to a PC resolution.

Sympt om: Scan or “fluttery” lines at top of video, usually on an analog cha nnel

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.

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.

Symptom: Tuner stays locked at Power On text

Reload the S37 firmware again (see

Alternate Update

note at the end of the

System Firmware

section on page 9). Call CR Support (888-

972-2728) to get the right firmware version for your tuner.

Contemporary Research

10

232-ATSC+1 HDTV Tuner

HDMI

Symptom: No Video or Signal

Most monitors accept HDMI in the RGB and Component color space, but there are exceptions. Try switching from RGB to

Component.

Switch between 720p and 1080i, or down to 480P or 480i for old DVI sets.

If you’re connecting via a Cat5 interface, HDMI receiver, or switcher, some delay the HDCP signal slightly out of range. Call CR

Support on how to extend the delay on HDMI.

Symptom: No audio or fluttering sound in display speakers connected via HDMI

Change ATSC digital audio to PCM or PCM variable (not all displays accept Dolby 5.1)

Sympt om: 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+1 provides on-screen captioning on all ports. No captioning

data

is carried on any HD port (HDMI, RGB, and Component standards do not support carrying captioning data). However, the composite video output does carry Line 21 captioning data when tuned to either an analog or digital channel.

HD2-RC IR Remote

The HD2-RC IR Remote included with the 232-ATSC+1 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-

Channel Selection

The key change in digital tuning is the need to add a dash (

RS-232/Telnet/UDP Control Protocol

Overview

The 232-ATSC+1 full duplex RS-232/Telnet protocol 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+1 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+1 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+1 units may be cabled together and addressed for individual control from a single RS-232 port. Each 232-ATSC+ 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+1.

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 to port 31931 (fixed) with status feedback on port 31932. Port 31932 is disabled by default, send “>UO” command (UF turns UDP off) or front-panel menu. See our

Support Blog How to Test 232-ATSC 4/ATSC+1 UDP Control to learn more about UDP control.

General protocol specifications

Characters in command strings to the 232-ATSC+1 are common ASCII keyboard characters.

Command strings sent to the 232-ATSC+1 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+1 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#

Command

Parameters

Return

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

A two-character command

Added attributes to some commands

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.

For compatibility with 232-series tuners, the 232-ATSC+1 channel status is split into Major Channel and Minor Channel sections. The Minor Channel will always be 000 for analog channels. The Minor Channel status will display “F00” if the

Major channel is a special “one-part” digital channel. Also, as one-part channels can go higher than 999, the Minor status will tell you how many thousands (up to 63) you add to the Major number. So, channel 1032 would show 032 Major F01

Multiple Tuners

Up to nine tuners can be daisy-chained from one RS-232 control port. Remember that you will need to use the Unit# address in your programming when you control more than one tuner from the same control port.

Set the first unit in the RS-232 chain to the highest Unit#, then wire in sequence to the last tuner in the chain. The reason for this is that

CR tuners use an intelligent data bus - the highest number tuner receives all commands, and then passes on commands addressed to tuners with lower unit numbers. The next tuner in the chain does the same, and so on until the last unit.
