Data 5:
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.
* 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 phys-
ical 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 0= Physical of 35 = 23
Data 1 & 2 = No Major = 00 00
Data 3 & 4 = No Minor = 00 00
Data 5 = 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 0 = Don't know Physical = 00
Data 1 &2 = Major is 30 = 00 1E
Data3 &4=Minoris3 = 0003
Data 5 = 0010 0010 in binary = 22
Total = ma 00 00 00 1E 00 03 22
