Data 01 & 02: Major Channel Number
Data 01: High byte Data 02: Low byte
Two bytes are available for the Major and
Minor, normally only the second byte is used.
Data 03 & 04: Minor Channel Number
Not needed for NTSC.
The table above lists the binary code which
must be converted to Hexadecimal before
sending. For example:
The binary code to tune the sub source to
an NTSC cable channel is 1000 0001, which
translates to 81 in Hex.
Data 05: Attribute
* 7th bit : For which source do you want to
change the channel.
* 6th bit: Use a two part or one part channel.
Most cases just use 0 since it’s ignored when
using NTSC.
* 5th bit: Use 0 with NTSC since it can only use
the physical channel number. Normally use 1
for ATSC since most times it doesn’t matter
what the physical number is.
* 4th bit: Set to 0.
* 3-0 bits: Choose signal type.
* Tune Command Examples:
1. Tune to the analog (NTSC) cable channel 35.
Data 00 = Physical of 35 = 23
Data 01 & 02 = No Major = 00 00
Data 03 & 04 = No Minor = 00 00
Data 05 = 0000 0001 in binary = 01
Total = ma 00 23 00 00 00 00 01
2. Tune to the digital (ATSC) local channel 30-3.
Data 00 = Don’t know Physical = 00
Data 01 & 02 = Major is 30 = 00 1E
Data 03 & 04 = Minor is 3 = 00 03
Data 05 = 0010 0010 in binary = 22
Total = ma 00 00 00 1E 00 03 22
* Use the feature depending on your model.

Example) To specify the value of the 5th band
(10 kHz) as +5:
To specify the value of the 5th band as +5,
100 in binary, which falls in 7th, 6th and
5th bit, is necessary. To calculate the value,
take 0, with the minimum value of -10, as a
base. Then the value for +5 is 15 that equals
01111 in binary. To consolidate these values
and send it as a command, first, put the two
binary digits together: 10001111. This equals
8F in hexadecimal. Enter jv 00 8F to use as a
command.
