Im finally happy with my hand-built-from-scratch config on my TSU9600.
My next goal is to integrate the 9400 IR extender unit into the project.

My hardware setup:

My home theater sources are located all in the same entertainment center.
This included the upstairs TV set, and I have hard-wired speakers all over inside that upstairs living room.

The basement theater room has the same speaker layout, also hardwired to the amp rack. Only one set of speakers is ever running at the same time, this is because I used electrical relays on each channel. All the relays when normally open just enable the upstairs set of speakers (and run 120vac to the upstairs powered sub). When I want sound in the basement, I push a simple button that closes all those relays. This diverts all audio to the basement speakers, including 120v ac to switch on the basement sub.

The basement TV and the UPSTAIRS TVs are both connected to the AVR's HDMI out via an HDMI splitter that's new even it supports all the fancy high tech HDMI edid data so I have no issues with 4k-HDR, Deep color, 3d, etc.

Both TV sets use simple IR control.

All other sources use IR control as well, but I did take the time and effort to take each unit apart, and zip tie an "IR BUD" internally, snaking the small IR LED cable out of a heat vent on each component. All these IR BUDs each get a mini phono mono plug.

These mini phono plugs all plug into a Xantech active IR repeater. The Xantech has two IR pickups. One in the upstairs living room (kinda redundant) and the other in the basement.

My plan is to possibly remove both these IR pickups. Wire up one of the 9400 IR outputs to the input of the xantech device (direct signal wire if possible, otherwise ill just let it light up an IR BUD and put it directly onto a pickup).

The idea is to have my 9600/9800 panels only send IR codes for the TV sets (they each use the same codes, but are located in different rooms). All other hex codes will be sent via RF to the 9400, and then hard wired into the xantech device.

I don't think I will need wifi or tcpip for this.

Simple RF should do it, right?

As I understand it, just set a channel on the 9400, then tell PEP2 what channel its on, and tell each hex code what port on the 9400 to use, right?

Any suggestions?

You nominate an output port for each piece of kit, so even though the TVs use the same codes, you can send them to different sockets on the extender and therefore control them separately.

Might you need another extender for the second room? Again, that's easily accommodated in PEP2.

If you use what is called 'Standalone' mode (the manual for RFX9400 is in the files section), there is an ad-hoc network created between the Pronto and the Extender and the Pronto can communicate with at most 1 extender.

If you go the Wifi route and don't use 'Standalone' mode, the Pronto, and all Extenders are devices on a 802.11b Wifi network and the Pronto can communicate with multiple extenders.

So, if you want to run IR emitter wires between several rooms, you can use a single extender. If not, then you'll be looking at multiple extenders.

Please take some time to read through the manuals as they outline alot of this stuff.

I might also suggest the Philips whitepapers here.

Fantastic info, thanks, guys.

Can the built-in IR LED still be used for just the TV set, everything else on the extender?

This way when I'm in the basement, that TV will see IR codes while the upstairs TV won't...and vise versa. I don't have "IR Buds" on the TV sets for this very reason.

All other equipment is located has IR Buds that all plug into the same wired IR amp. The only AV equipment in the basement that has IR control is the basement TV set.

I am working my way thru the manuals.

Yes. It is possible.

Read the manuals. More good things to help explain this system can be found in the Philips Certification (Level 1 and Level 2) documentation.

Also search the Files on this site using keyword "Certification".

will do, thanks.
