JP1 Remotes

I've just noticed a new variation of the "Pioneer MIX" protocol that's in a few newer remotes (including the URC-6131, URC-9960, URC-8040, URC-3440, 15-2138 and Altas remotes).

The current MIX protocol has 4 fixed bytes & 2 variable bytes where:

fix1 = device1
fix2 = command1
fix3 = device2
fix4 = command2

var1 = OBC
var2 = control

if control (bit0) = 1, use a 2-part signal, otherwise use 1-part
if control (bit1) = 1, use dev1/cmd2 for 1st part, otherwise use dev1/cmd1


The new version has 6 fixed bytes & 2 variable bytes where:

fix1 = device1
fix2-5 = command1 thru 4
fix6 = device2

var1 = OBC
var2 = control

if control (bit0) = 1, use a 2-part signal, otherwise use 1-part

control bits 1 and 2 form an index, which is used to decide which fixed byte to use for the command code on the first part of the signal.


My recommendation is that KM and RM be modified to allow for the new format when the MIX protocol is selected. I also recommend that a new selectable entry called "Pioneer MIX 4Cmd" be added, which would allow people with older remotes to use it, if they need to.
