Just got the new rfx9600 up and communicating with the TSU9600.
One issue so far, is that my preamp/audio processor's built in ir repeater won't work with the RFX9600 output. The ir works perfectly thru the front sensor.
It's an Anthem AVM30.
The manual states that the repeater uses a 38khz carrier to trigger the repeater, and won't work with straight ir code transmissions.

Question:
Does the RFX9600 use a carrier frequency, and is it adjustable?

Otherwise I'll just have to re-run the Anthems ir outputs and combine them to the RFX9600. Probably have to do that anyway once I get the serial control on the Anthem working.

A question;-

Is the RFX 9600 using a direct connection cable 3.5mm Mono jack to 3.5mm Mono jack , or a IR stick on Bud?

The carrier frequency of the RFX can go from 20khz to 1Mhz but you can not change it on the fly, the frequency has to match your Device.

It's a direct 3.5 to phoenix connector (the AVM30 can repeat up to 3 incoming ir signals).
Is the RFX carrier randomly variable, or is it based on the ir code it's transmitting?
And thank you for the quick response :-)

The carrier frequency is not random , the frequency id determined buy the Device, DVD, TV etc, the most common is around 36Khz , but it does vary pre manufacture .

If your AVM30 has a filter of 38Khz on it it will only pass IR signals with a 38khz carrier, so you will have to use other outputs from the rfx to control the other devices.

You say that the IR through the front sensor works fine. Did you sent that code via the TSU9600? If no, then you should learn the code into the TSU9600, and then map the device you learned the code for to the extender's IR output port.
The carrier frequency is part of the IR code data, in other words, is set automatically when learning the code into TSU9600.

The front ir port is working fine with the TSU9600 thru the rfx extender.
With the old TSU7000 and its rf to ir repeater the rear wired ir port on the Anthem worked fine and passed the ir codes on to 4 different pieces of gear without issue (3 Sony DVD carousels and 1 Denon DVD player).

The only difference is that with the TSU9600 I'm using the stock ir codes from the Philips database for the Anthem & Denon, not the ones recorded directly from the remotes that I had to use with the TSU7000. I'm using ir codes for the Sony carousels recorded directly into the TSU9600.

All codes for all gear work fine coming out of the RFX9600 going directly to each piece of gear. In fact, I found an old Xenix ir expander from a project, that I wired via 3.5mm to 3.5mm to the RFX9600 that is working fine sending signals to the 3 Sonys and the Denon.
It's just the rear wired ir input of the Anthem that won't see ir output from the RFX9600 and pass it along. Very odd.
