I am hoping somebody can give me some advice on what might be causing the issuing I am experiencing or point me in the right direction.

I have a TSU9600 linked to a RFX9600 which until a couple of week ago controlled everything in my system via IR with no issues.

I then decided to control the Lumgen Mini3D video processor via serial to free, I have the codes programmed and connected via the standard serial cable that came with the Lumagen. Bingo the RFX9600 controls the Lumagen is seems faster than when controlling with IR.

However, the RFX9600 then stops sending any IR commands to any other devices. The RFX9600 lights up to say it is sending the commands, but they are not reaching the other devices. If I disconnect the Serial cable, it all works fine.

I have tried a new Serial cable which is wired Straight Through and all of the serial ports but get the same issue.

Anyone any ideas on this?

You did not mention if using PEP1 or PEP2. Extender configurations are different for each. This being said, I will presume it is a hardware issue for now.

If it is a hardware problem, sounds like a ground loop on the Lumagen to RFX.

Easy way to test is to simply disconnect the Lumagen from the RFX9600 without changing your configuration. If all things work except for the Lumagen, then this is likely your issue. Also, how is the Lumagen connected for IR to the RFX? Is it connected using a mono/stereo cable between RFX and jack on back of Lumagen or did you use the stick on emitter? If the former, power off all equipment and disconnect that cable and retest.

These 'other' devices, are they configured to send IR commands through the same RFX or directly from the Pronto?

Thanks for your reply.

I am using PEP2. You are right in that if I disconnect the Lumagen and don't make any other changes everything works.

I am using the emitter stick on the Lumagen as it does not have a IR remote input. All other devices are connected through the RFX9600, the remote does not output any IR commands, they all go through the RFX9600 and either emitters or direct cable connections with mono cables.

How do I over come the ground loop, do I need a serial cable which only has three of the pins connected rather than fully wired?

For Serial cables, only pins 2, 3, and 5 are used on the RFX9600. Unfortunately, you cannot forgo any of these 3 connections.

I am interested in what types of equipment you have connected to the RFX9600 via the mono cables. Your only solution may be to replace these cables with emitters. I would start by powering down everything and replacing the mono cables 1 by one. If you have more than 1 mono cable connected, then remove all cables and replace with emitters until you are left with 1 mono cable only. If you still have issues, then you may find that you need to do trial and error on switching out various mono cables.

I do know first-hand that the ground side of the IR ports is not isolated per port so if using Mono cables, you can get some bleed through between ports. I experienced this with Escient equipment and Belgium confirmed my suspicions of a shared ground.

Again great insight, thanks.

I have checked and I only have one connected by a mono cable, which is my Tag Processor.

I will follow your advice and see if I can resolve.

Unplug the Tag and leave 232 connected. If all works then put an emitter on the Tag and try again.

Now, my reason for asking PEP1 or PEP2. When you said PEP2, my first thought was that you might have tried to simulate at one time and the only way to do that without using Jon Welfringer's SIM patch was to set each component to send IR only.

PEP1 had no real simulator so we were pretty much crippled there. That's why you've likely heard about the Base Station Mod and Barry Gordon's Pronto Debugger.
