i have just got a Pocket PC and already had a Pronto TSU2000. I was under the impression I could simply load my CCF into Total Remote and away I go. Problems though. Loads ok and I have access to my Pronto CCF but no devices respond to any IR commands from the CCF.

Am I doing something obvious wrong ? Does it need to be converted somehow first ?

The Total Remote package is working if I use it in Standard mode and learn commands from scratch.

My Setup:
hp iPAQ h4350
Philips Pronto TSU2000
Total Remote v2-1-381

Have done some more research ...

Looked at the Griffin IR transmitter using a digital camera and I can tell the ccf is transmitting, but a very very weak signal.

The 'standard' layout is transmitting a much stronger signal.

Help.

It all depends on which pda you use.

are you saying this is as good as it gets with an iPAQ h4350 ?

Just to be clear, are you saying you get a stronger transmission when using Total Remote's native mode versus transmitting a signal from within CCF mode?

It would appear that way to the naked eye. But then I guess it could also be because I have previously cleaned up my codes in the CCF using ProntoEdit on my TSU2000

Don,

I will say that this triggers something I have found as well. The IR signals are "louder" and "Brighter" using Native mode than CCF mode. Usable distance is far greater in Native mode. This is observed on both my IR extender pyramid and a CCD camera...

The "brightness" of the CCD camera is misleading. The "native" (IrDA emitter) uses a wavelength (850nm) that is closer to visible light than a CIR emitter (940nm) and the camera, being optimized for the visible spectrum will show the IrDA emitter as being brighter but the CIR emitter should give better range. If it doesn't, there's probably something else amiss, like the carrier frequency being too far off what the receiver is designed for.

The Powermid uses a 40kHz IR receiver.

The duty cycle of the carrier will also have an effect on perceived "brightness".

The latest PDAs from Dell, HP and others use a compromise wavelength of ~885nm which explains why they offer better CIR range than earlier PDAs.

You have brought up a point which is remarkably easy for me to test, so I will. If it turns out there is a difference in output power, IrDA or audio, it will indicate a flaw in the CCF mode code that should be readily fixable.

Don, I just thought of something. Could this be related to the fact that there is no "warm-up" tone generated for the Griffin device in CCF as there is for the Native mode? just a thought...

TJD

Not too likely. The technical reason for the "warm-up" is to stabilize the audio hardware by getting it "up to speed" before we transmit actual IR data (we play a sound before we play the "IR command" sound). It should have nothing to do with relative brightness of the LED. Good thought, though!

Hi, I also am having trouble getting a ccf file to control an Aiwa system using Total Remote on my ipaq 3750 . Is there a way to diagnose the problem?

Thanks,
Jerry
