OK, so after a bit of research it appears that the Xantec codes are NEC1 protocol and the different code groups are just different device codes (10=code group 30, 40=code group 4). The function code numbers seem to be the same for each device number.

As much as I would like to geek out over this I am wondering if someone has been through this already and can confirm or deny my assumptions.... and I am wondering if someone has a list of the code group-device number associations.
