I just recieved some bad news about these commands 
Well not so bad if you have a SC9000 
Seems they use a slightly different protocol common to european x10 security devices (41 bit commands instead of 32 bit commands) 
Why was this added to the SDK
Tuicemen:
Most USA version X10 security devices send 41 bit codes, at least the DS10A, MS10A, KR10A, and KR15A units I own all do.
The one exception I own is a SH624 (date code 03L52) which sends a 32 bit code. Newer SH624 units may be different however, given that X-10 is known to make drastic changes in their devices without warning or change of part number.
If you register X10 security devices with OnAlert and then look in the .ahx file, you'll find a 16 bit security ID there for the 41 bit devices.
(The ID field for a 32 bit device is only 8 bits).
I receive both 41 and 32 bit codes with a 310 MHz RFXCOM RF receiver in variable length packet mode. In 32 bit W800RF32 emulation mode (or with an actual W800RF32A) only the lower 8 bits of the ID is reported.
Europeans owning the 433.92 MHz RFXCOM RF receiver receive similar 41 bit codes from most European X10 security devices I'm aware of, but I haven't had anyone report about the European SH624.
