I'm posting some interpreted observations - if/where my interpretations are incorrect, please let us know...
1. If you have a DS7000, and your HouseCode (HC) is set to "F" (for example), the DS7000 "Monitors" all HC=F traffic. Further, no other application (AHP) or tranceiver is necessary for any device addressed as HC=F to be operated from any (remote) transmitter, because the DS7000 receives the RF command from the remotes (transmitters) and sends the command back out via the powerlines to the target module.
2. The only purpose of a tranceiver, and/or having the CM15A tranceive HouseCodes is if something (like a remote) is going to issue an RF command for a module that is not addressed to the MONITORED HouseCode of either the DS7000, or the CM15A.
3. (not sure on this one) - If the CM15A is plugged in to the PowerLine, AND the Tranceived HouseCode(s) is set to AUTO then ALL transmitted RF commands to ANY HouseCode will be received by the CM15A and sent out (transmitted) over the PowerLine to the target modules. If the Tranceived HouseCode(s) is set to NONE, no transmitted RF commands (other than those for the MONITORED HC) will be transmitted over the PowerLine. Likewise, if SPECIFIC HC(s) are checked, ONLY those AND the Monitored one will be transmitted.
So here's a question: I think the CM15A receives (and records) all RF transmitted commands, and if it is plugged into the PC running AHP - it will transmit all commands to AHP and therefor the AHP and the CM15A can & will operate macros from all HouseCodes - then those macros can cause COMMAND transmissions to the PowerLine and modules on any HouseCode. Right or wrong?
(All of this assumes there are no range/distance issues)
