Hi,
I own an RC9500 with an RF extender RX-77. My RC9500 is working perfectly alone for the devices (BOSE, FORCE, NEC) the discrets codes come from remotecentral.com.

When I am usig the RX-77 rf extentder i have some problemes with the Force 500 series (DVBt) the signal seem to be sent 2 times, for instence if i press button "1" i get "11", chanel up gets 2 chanels up an so on for each button. This problem seem to be specific for the force 500 since all other devices are working nicely.
I use the clean FORCE code from this link:
[Link: remotecentral.com]

Exempel button 1 (Force series 500)
0000 006C 0012 0012 0008 001D 0008 005B 0008 001D 0008 006B 0008 0032 0008 0032 0008 001D 0008 0060 0008 021B 0008 001D 0008 006B 0008 001D 0008 001D 0008 001D 0008 001D 0008 001D 0008 0022 0008 0C20 0008 001D 0008 005B 0008 001D 0008 006B 0008 0032 0008 0032 0008 001D 0008 0060 0008 021B 0008 001D 0008 0041 0008 0047 0008 001D 0008 001D 0008 001D 0008 001D 0008 0022 0008 0C20

Any ideas

/Dag

have you tried sending the code direct with IR on the remote to see if it is sending double codes?

Yes, there is no problemes directly from the remote, all codes are doing well. That only when i am using the rf extender. I ve tryed changing the position of the RF and add delay but nothing helps. Note there is only problem with the Force Series 5.

Dag,

Note that you may also have to set the IR Code duration.

Change the first 4 groups of 4 numbers in the code to the following and retest:

Test #1 - Repeating only

0000 006c 0000 0024

Test #2 - Non-repeating only

0000 006c 0024 0000

thanks for the help!

The test #1 doesnot work att all. Test #2 works but seem to be slow, and some times i have to press the buton several times.

A perfect version of this signal has three parts: an initial frame to say the button was pressed, a repeating frame to say the button is still held, and a final frame to say the button was released.

A Pronto generally can't learn the final frame, and I haven't heard of any problems being caused by lacking the final frame, so I don't think that is part of the problem here.

I don't know what causes the symptom because I don't know exactly what the RC9500 sends when using IR directly vs. what it sends via the RX-77.

Do I understand correctly that the RX-77 uses RF from the RC9500 itself (not from some intermediate IR to RF conversion)? So the firmware of the RC9500 knows the intended path is via RF? So it could make some change in what it sends that the firmware programmers thought would be benefitial for RF but in this case is harmfull.

I wouldn't be surprised if the choice of RF changes the number of frames of the repeat part that is sent. But I also wouldn't be surprised if it changes some other timing detail. This protocol is rather touchy about timing details.

Test #1 above alternates the press frame with the hold frame. I wouldn't think that would be a good thing, but I also wouldn't try to guess what the IR receiverr in the Force would interpret it as.

Test #2 above sends exactly one press frame followed by exactly one hold frame. That was a good thing to try and I'm a little surprised the results were so disappointing. With that version is there still a significant difference between the way direct IR responds and the way IR via RF responds?

Maybe the device needs more than one hold frame but not so many as the firmware is providing with the original Pronto Hex. You could construct Pronto Hex with a few of the hold frame, such as this one with two hold frames:

0000 006C 0012 0024 0008 001D 0008 005B 0008 001D 0008 006B 0008 0032 0008 0032 0008 001D 0008 0060 0008 021B 0008 001D 0008 006B 0008 001D 0008 001D 0008 001D 0008 001D 0008 001D 0008 0022 0008 0C20 0008 001D 0008 005B 0008 001D 0008 006B 0008 0032 0008 0032 0008 001D 0008 0060 0008 021B 0008 001D 0008 0041 0008 0047 0008 001D 0008 001D 0008 001D 0008 001D 0008 0022 0008 0C20 0008 001D 0008 005B 0008 001D 0008 006B 0008 0032 0008 0032 0008 001D 0008 0060 0008 021B 0008 001D 0008 0041 0008 0047 0008 001D 0008 001D 0008 001D 0008 001D 0008 0022 0008 0C20

yes, the RC9500 sends the RF signal directly to the RX77



with IR direct from the RC9500 the commands are very quick (has quick as the original remote, But trough the RX77 (RFmode) the commande using test#2 are very slow and seems to be miss understand



Just tried, its get 3 quick "1"

Well Force Ir codes seem to be tricky
