I am very interested in trying your idea of playing
audio files (bypassing the Total Remote infrared-to-
audio algorithm) to see if that works. Perferably with
the Harman Kardon receiver.
The trick here is to find a way to make it. We have no HK receivers in our database, but I do own a AVR65 and I could always try sampling some of those buttons to see if they would work for you. Another possibility would be to use a CCF that has your HK codes, and I should be able to generate audio files from that.
Is it possible that a flaw in the infrared-to-audio
algorithm could affect the range of the audio
transmitter on some devices?
Quite conceivable, but far from certain.
How do the LEDs on the audio transmitter compare
to the LEDs in a standard tv remote as far as
the spread of the beam? From what I have observed,
you seem to have to be fairly precise when you
point the PDA at a device to control it. With
a standard tv remote, you don't have to be near
as accurate (reflecting off a wall or ceiling
will even work).
Most OEM remotes use LEDs with larger beam angles, and they can dump as much power to them as they want. The Total Remote audio transmitter is rather limited by the power that can be generated by the audio port, and this is obviously far less than 2 triple-A batteries. As a compromise we selected the most efficient LEDs we could find, and that also meant they had fairly tight beam angles. Without using an external battery there is no way we can get around this without dramatically reducing the range.
I'm wondering if it would be worthwhile also trying
previous versions of the Total Remote software?
It would probably be worth trying, but we do not make older versions publically available. If you would like to contact us at trbeta_at_griffintechnology_dotcom we can send you some of the older versions, particularly those designed at the time of the e740.
