Sorry to ask such a silly question, but this one has me stumped...

I just setup a TSU7500 for my boss (I have a 3000.)

Anyway, he has the following:
TSU7500 + RF Base station
Samsung Plasma
Samsung DirecTV HD Receiver
Toshiba DVD
Yamaha Receiver.

I set everything up with IR. Everything worked.
Each device has a IR page, which contains all the codes for each device.
All buttons & macros use links to these pages.

I enabled RF.
I did this by changing the device properties page to use RF instead of IR.
I started off on CH0, ID0.
I changed to RF for the Receiver, DirecTV & DVD.
The plasma remains on IR as it's in direct line of sight.

Okay, so what's not working?
Well, about half of the codes for the Samsung DirecTV box get dropped.
eg I have a macro to tune to ESPN.
The Macro does this:
Link - DSS - IR - 7
Delay 0.1
Link - DSS - IR - 3
Delay 0.1
Link - DSS - IR - ENTER

I changed the delay from 0.1 to 0.2 to 0.5, but it makes no difference.

I changed the RF channel from 0 to 1, but it makes no difference.

I finally pulled up my IR page (that's normally hidden) and pressed the buttons manually.
When I press the IR code button directly, they only work about half of the time.
If I switch back to IR, they're fine.

I have re-learned the codes, and it makes no difference.
I have told the system to use the built-in codes. They work with IR but continue to fail via RF.

Does anyone have any ideas what I can do to get the RF to work better?

Other things to stress.
1. All the other devices work just fine.
2. I have tried repositioning the eye for the IR blaster.

Thanks.

Nick,

Assuming when you changed the RF on the Properties page, you are also changing the settings to match on the RF box?

Plasma can cause a lot of interference. Is the RF indicator on the box flickering when you are not transmitting a signal? If so, that would indicate interference. Try some RF things with the Plasma off, see if that makes a difference.

Which RF unit do you have, the newer RFX6500 or the older RFX6000? The newer one is more stable against interference and the external antennna can be positioned, to get as far away from interference as possible.

I have re-read your notes several times and in general you seem to have it setup fine. IR pages are within the device and then set the device to RF.

It sounds to me to be interference or possibly a bad RF unit.

HI Dave, thanks for answering so quickly.

I have the newer RFX6500 unit, and have tried moving the antenna around.
I have the antenna in a cupbard right now, but have also placed it in the open 4 feet above the components.
The plasma is wall mounted about 10 feet away.

Yes, when I changed the channel in the software, I also changed it physically on the box (and removed and replaced the power cord to make sure it started over.)

The interesting thing is that the other devices are working just fine.

When I was typing the first message, I realized that I did not check a different IR blaster cable, or plug the existing cable into a different port. I will try that next time I'm out there.

If anyone else has any ideas, I'm all ears. :)

Thanks.

Be sure that the stereo connector that connects the ant. with the extender unit is seated ALL the way in. It should feel like it snaps into place. This was the problem with the first couple I installed. It is much more snug than the IR emmiter connections. I have also seen a co-worker make the same mistake so I know I'm not the only one.

Nick,

Are we just working on the Plasma at this point?

If you are using an IR emitter to the plasma, try repositioning. Sometimes they actually overload the IR receiver when placed directly on top. Move the emitter a few times and keep experimenting.

If just the channel macros are not working, try increasing the delays.

Dave

yeah, this is really bugging me...

The antenna is definitely in (i get a light) and the RF to the DVD & Receiver work OK.

If I go to the page with all my IR codes on it and hit a number like 7, it only works sometimes.
There does not appear to be rhyme or reason as to when it doesn't work. Pressure or duration make no difference, nor does learning the codes vs using internal codes.

As I said in my last post, I need to check the IR cable and the jack; perhaps even verify where the IR eye is on the DSS receiver.

oh well, thanks for the suggestions guys.

That would be my next suggestion. I have problems from time to time with a particular Pioneer DVD player because it is very sensitive to where the emmiter is placed. Just a little off to the side and it will only respond to some commands, and not every time.

Rich

Some DSS receivers suffer from "overload" from the IR emitter. Try a spot on the bottom of shelf above the unit, near the receiving eye. Or swap out the receiver eye and put it on the DSS receiver and see if it works any better. Might then be what Rich recommended.

Dave

That reminds me, you can change the strength of the ir signal since you have the 6500. That's what the dip switchs are for. The settings are in the manual. I believe the default is full strength and changing them will weaken the output if needed.
