“Transceived” –vs.– “Monitored”

In January, 2007, Puck wrote:

Transceived: Means that if an RF (Radio Frequency) signal from that HouseCode is received, it will be placed on the power lines (transceived from RF to PLC)

Monitored: Is the HouseCode whose units can be used for macro conditions (if On / if OFF)

…and over the past several months I've read that several times. I thought I understood. Then in July, I was playing with conditional macros and finally the differences gained meaning. The two terms really aren't even close.

Fig-#1:

"Transceived House Code(s)" – None – Auto – Specific. For the purposes of X10, a TRANSCEIVER receives RF signals through the air from sensors, remotes, or AHP via the CM15A and then converts those RF signals to PLCs (PowerLine Commands) and transmits those PLCs onto your house wiring.

Example:

Suppose you had a LM465 (Lamp Module) set to HouseCode (HC) "L", and UnitCode (UC) "5". When you have your PalmPad (HR12A) set to HC="L", and you press the "5=ON" button, the PalmPad sends an RF signal, "L5-ON". The LM-465 doesn't respond to RF, so something has to translate the RF signal into a PLC signal and send it out over your house wiring. That operation is called "transceiving". The CM15A is (among other things) a transceiver. If you have your CM15A set to transceive HC "L" either SPECIFICally, AUTOmatically, or if you have it set to MONITOR HC "L" (the Monitored HC is also transceived), when the CM15A receives an RF signal for HC "L", it will generate the PLCs necessary to accomplish the task and send them out over the house wiring – the LM465 receives those PLCs on the wiring and turns on the light.

What you'll see in the Activity Monitor is:

  0020    9/1/2008    7:48:20 AM    Receive RF    L5 On

    0021    9/1/2008    7:48:21 AM    Receive        L5 (LivingRoom Lamp)

    0022    9/1/2008    7:48:21 AM    Receive        L On (LivingRoom Lamp)
