Ocelot toast?

This morning i noticed that some of my domotica stuff isn't working anymore. This was caused by the ocelot that seems to be broken.
The 'comms' led on the modules are lit continously (instead of blinking). Also, de X10/IR LED on the Ocelot is lit somewhat (not fully, but it is noticeable). When I remove the X10 RJ11 cable the light goes out.
The 'active' green LED blinks sometimes, but not as regularly as it normally does.
Any ideas what might have been broken? My device is +/- 3 years old.

How is the Active light flashing?
It might need a new 29040 chip or may need to come in for repair.

The active light flashes once every now and then. Must less often then normal. I didn't count it, but i think somewhere in the range of once every 8 tot 10 seconds.
Can I order a new 29040 chip? I'm afraid sending the whole unit back and forth from The Netherlands might be quite costly and its cheaper to buy a new unit.

I disconnected the Ocelot but I'm beginning to think there might be more problems. The 'comms' led on my Secu16 keeps lit continously even when the 'data A+B' wires are disconnected. However, with the Secu16 disconnected the Ocelot still does not respond to X10 commands.
I also noticed the 7805 on the Secu16 is getting warm. That should not happen with a device only doing 200mA. Perhaps something is wrong with the power supply (laptop power adapter).
I'll tinker with the Ocelot and try to connect some other modules I have lying around to see if perhaps only the Secu16 is broken, or both or just the power supply.

I have done some testing, and I noticed 3 issues:
- The Secu16 COMMS led is lit even when the COM A+B are disconnected. Any other unused module I had lying around has a blinking comms led. So the Secu16 seems to be different (read: broken)
- The comms led on the Ocelot does not blink at all. I am also unable to detect any modules using the Ocelot. My guess is the Ocelot COMM bus is also broken.
- There seems to be 'something' with the RJ11 X10 port. I swapped the CM11 (or whatever the thing is called) with a new one, and the little red LED on the CM11 starts blinking as soon as I connect it to the Ocelot. It should only blink when receiving/sending data. the Ocelot is still able to send X10 commands but not able to receive them.
My guess is something went foobar and took the Ocelot and the module with it. I'll check 5V line in a few hours.
I'm beginning to think I have to buy both a new Ocelot and Secu16, which will set me back +/- 400 euro 
Since both units have been running for years I'm wondering what could have caused this. The only modification I've made is connecting an 'rfxcom rfxmeter' to one of the Secu16 supervised inputs, because I've also hooked a watermeter with pulse output to this input. Could the little current that the RFXMeter puts on the line toast both the Secu16 and the ocelot?

The right product type is XM10. I have 3 or 4 of them, and they do not blink (unless there is actually going something on on the powerline). It starts blinking heavily as soon as I connect it to my Ocelot.
The serial interface in the Ocelot seems to be okay. I can program it, read timers, set timers, etc, etc. No problems there. The only problem seems to be in the communication with other modules and the X10 stuff.
I've indeed tried the C-Max monitor X10 utility, and switched some lights using HomeSeer (I do not use Ocelot to control X10 devices in homeseer). It did not notice any X10 commands.
I've send an email to my supplier, asking if I can return any item that I do not require (if my current unit turns out to be okay)

Okay, I narrowed it down some more. The X10 interface is also working alright. THe other XM10 I had was using another pinout on the RJ11 jacks, so that caused the heavy blinking of the led.
The only remaining problem is the RS485 communication to other modules. This seems to be right, since the COMMs led on the Ocelot does not blink at all. Its always off. The COMMs led on the modules do not chance in behaviour when I use the auto adressing mode, even when they should to start blink heavily according to the manual.
Are there some IC's I can swap myself that might have been fried in the RS485 circuit?
I have swapped the "sn75176bp" with a spare Ocelot extension module, but that didn't help anything.
