Data 0 5:
The table a bove lists thebinary code w hich m ust be
converted
toHexadecimal
before sending.
For e xample:
The binary code t otune the sub source toanNTSC
cable c hannel is"1000 0001 " ,which t ranslates
to"81 "
inHex.
7thbit:For w hich source doyou want tochange 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 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 05
Data 05 = 0010 0010 in binary = 22
Total = ma 00 00 00 1E 00 03 22
