EXTERNAL CONTROL DEVICE SETUP
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 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
22. Channel Add/Del (Command: m b)
To add and delete the channels.
