SpitFIRE Block Diagram

isn’t programmed yet while punch-thru if off,

you will get a No-Device-Programmed Status

message (0xB4). However if punch-thru is

enabled, and no device has the desired button,

you will get a Button-not implemented status

message instead.

Punch-thru mode is toggled with scan-code 90

(5Ah).

If punch-thru is toggled ON, the SpitFIRE will

return a 1 flash status message (0xA1).

If punch-thru mode is toggled OFF, you will get

a 0 flash status message. (0xa0).

Punch- thru will be affected by learned

functions. For example, if you are controlling a

VCR and issue a VOL +, the volume command

will normally punch-thru to the proper device.

However, if you learn a new code onto the

VOL+ button, it will no longer punch-thru.
