• Analog Antenna/Cable
(Data 00): Physical Channel number
- Antenna (ATV): 02 ~ 45 (Decimal: 2 ~ 69)
- Cable (CATV): 01 ~ 7D (Decimal: 1 ~ 125)
(Data 01 ~ 04): Major/Minor Channel number

- (Data 03) & (Data 04): xx (Don’t care)
(Data 05): Input Source (Analog)*
- 00: Antenna (ATV)
- 01: Cable (CATV)
• Digital Antenna/Cable
(Data 00): Physical Channel number**
- Antenna (DTV): 02 ~ 45 (Decimal: 2 ~ 69)
- Cable (CADTV): 01 ~ 87 (Decimal: 1 ~ 135)
(Data 01)(Data 02): Major Channel number

(Data 05): Input Source (Digital)*
- 02: Antenna (DTV), Use Physical Channel number
- 06: Cable (Auto***) (CADTV), Use Physical Channel
number
- 22: Antenna (DTV), Do not use Physical Channel
number (see also (Data 00)** above).
- 26: Cable (Auto***) (CADTV), Do not use Physical
Channel number (see also (Data 00)** above)
- 46: Cable (Auto***) (CADTV), Use Physical Major
Channel number only (One Part Channel)
- 66: Cable (Auto***) (CADTV), Use Major Channel
number only (One Part Channel), Do not use
Physical Channel number (see also (Data 00)**
above)
* Installer Menu items 003 BAND/AFC and 102 ATSC
BAND select the tuning band(s) for the display. In
order for the tune command to be executed, the
Input Source value for (Data 05) must match each
tuner’s tuning band setting.
** When (Data 05) is 22, 26, or 66 (see below), use 00
for (Data 00).
*** Cable bands Cable Std - x3, Cable HRC - x4, and
Cable IRC - x5 can also be used in (Data 05) lower
nibble.
Two bytes are available for each Major and Minor
Channel number. The high byte is 00 unless the
channel number exceeds 255.
Tune Command Examples:
Example 1: Tune to analog cable channel 35
Set ID = All = 00
(Data 00) = Channel Data is 35 = 23
(Data 01) & (Data 02) = No Major = 00 00
(Data 03) & (Data 04) = No Minor = 00 00
(Data 05) = Analog Cable = 01
Total = ma 00 23 00 00 00 00 01
Example 2: Tune to digital antenna channel 30-3
Set ID = All = 00
(Data 00) = Don’t know Physical = 00
(Data 01) & (Data 02) = Major is 30 = 00 1E
(Data 03) & (Data 04) = Minor is 3 = 00 03
(Data 05) = Digital Antenna = 22
Total = ma 00 00 00 1E 00 03 22
