Apologize for the length.... I am currently using AHP and the CM15A and the XTB-IIR as a repeater. Thanks to Tuicemen and others, I have AHP rebuilt on a Win7 system after losing my XP one. After installing AHP again from posted files, and there may be a little Marmitek in there too, I noticed that my LM465's started operating differently. Instead of coming on full bright and dimming to the AHP programmed level, they ramp from off to the set level. I am currently designing a new Arduino controller board to get a web interface and other features and to wean off of the CM15A. I am sending commands to the XTB-IIR TW523 emulation port. In sending commands to the LM465 I now can do it both ways, come up full on and Dim and go directly to the desired level. However, I stumbled across the going directly method as I have not seen documentation on this. If I select the Unit, send it an On, and then delay and then send it a Dim, the lamp dim level will be set by the amount of delay between the On and Dim commands, from 0 to 1 second. (0 very dim, 1 second full bright minus 1 dim step) Obviously there are small software program execution delays in there too. I have repeated this over and over reliably and tried all my spare LM465's and they all work this way (They are soft start ones). After a long, non-successful Google search, my long story question is, has someone documented the firmware operation inside this and other wall / lamp modules that Dim or have any comments on what I am observing? I have a big collection of X10.com modules and want to keep them going. Thanks.
