Mark's not going to know how to answer this, as I added these two protocols to KM. I guess I mis-interpreted how IR is displaying the data then. The Teac signals are displayed as device code 0 and sub-device code 4 and I treated these as though they "Panasonic" device codes.

I guess I'm going to have to dig out my Kaseikyo spec and re-visit this coding.

John, am I right in assuming that what you call "device code" in DecodeIR (via IR.exe) is the 4-bit "Div" code, and what you call "sub-device" is the 8-bit "Appliance" code?

Here is what I thnk is the comparison between the two protocols:

TEAC-K {37.9k,432}<1,-1,1,-3>((8,-4,M:8,N:8,X:4,D:4,S:8,F:8,C:8,1,-100),(8,-8,1,-100)+)
where:
X=M(0..3)^M(4..7)^N(0..3)^N(4..7)
C=D+S(0..3)+S(4..7)+F(0..3)+F(4..7)

Kaseikyo {37k,432}<1,-1,1,-3>(8,-4,M:8,N:8,X:4,D:4,S:8,F:8,E:4,C:4,1,-173)+
where:
X=M(0..3)^M(4..7)^N(0..3)^N(4..7)
C=D^S(0..3)^S(4..7)^F(0..3)^F(4..7)^E

BTW, the ^ means XOR and F(4..7) means the top 4 bits of F

Not relevant to this discussion but to help understand the notation, the Teac has a one-time data frame and a null repeat segment like NEC1. Kaseikyo has the entire frame repeat.

Rob,

I thik you are referring to this table from Panasonic:

There are 48 bits in a Kaseikyo format. These bits are assigned as follows:

Subgroup # of bits
Manufacturer code : 16 bits (2002 hex)
Parity : 4 bits- calculated value
Division :4 bits ( 8 hex)
Appliance : 4 bits- for TV ( 0 hex)
Control : 4 bits- for TV ( 0 hex)
Function Data : 8 bits
Parity :8 bits

So I think the answer is Yes but S:8 is Control:4 Appliance:4 (you have to reverse the order)
