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.

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

*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
