RE: Upgrade CM9000 to CM9001/A - Home - 06-15-2026
(06-14-2026, 04:37 PM)cc_uk Wrote: This weekend I swapped the CM9000 for the CM9001/A
Everything has gone well, but a few observations and questions
The CM9001/A is running Firmware 8.034. It's inbuilt UCM running 8.023
The system has the ETH03 module directly installed on the CM9001/A board.
There is a LEM connected via the ribbon cable, and a SEM running 7.207
I have two keypads - both KP01A running 7.016
Finally an 8 button SCS version 2.004
My first question - does the in-built UCM get updated with the main controller firmware or separately?
My main issue is around the 8 button SCS. Initially is scanned OK but then I started to see communications failure and it would appear with random IDs when scanning.
Jumpers ABCD all had a link set on them which should indicate Id 1.
I removed all jumpers cleaned the contacts, which looks good anyway, and got the same result. I used a meter to confirm that continuity was set on all 4 jumper pairs - and again all checks out OK.
By deleting the SCS and then re-scanning it has appeared again with Id 1. However when I press any of the buttons on the SCS - Comfort does not respond with the response I have set for them, and the LED just flashes continually after that. in SCS/RIO responses I have set it to monitor, and all of the ModuleStatus for 129-136 always stays set to Off
I am also using the SCS temperature monitor the value from this does appear to be being read into Sensor08
Any ideas? I know the SCS is old, but hoping it is still compatible with the ARM edition of the controller, especially as there is nothing to replace it.
Lastly since I have the latest controller now - should it return it's serial number when scanned? As mine doesn't.
You dont say what version of comfig you are using - in my last recent post I have suggested that Comfig 4 should only be used on totally new installations.

Hi Thanks for your replies - I am using Comfigurator 4.0.4.0. I do have just the one SCS yes - the 8 button version.
The temperature sensor is still being read properly by Comfort, so it is communicating, just the buttons and LEDs don't appear to work now.

could the scs have become faulty since you changed the controller?
RE: Upgrade CM9000 to CM9001/A - cc_uk - 06-16-2026
Anything is possible of course. So to help troubleshoot... Since I have not yet redeployed the CM9000 that the new CM9001/A replaced I set it up on the bench and connected 1 keypad and the 8 button SCS to it. On the CM9000 the buttons on the SCS work correctly, when I returned it to the CM9001/A it did not work - the temperature sensor did, but none of the buttons do and just flash red.
What I did notice is that if I run the bus monitor - that worked on the CM9000 but on the CM9001/A I see no bus monitor output. I know the bus is working as the two KP04A keypads work, and it can read the temperature sensor on the SCS.
I have a UCM connected via the 4 pin connector and that also works correctly.
Therefore it seems as if either there is some problem with the bus on the CM9001/A resulting in the bus monitor generating no output, and/or the SCS doesn't work with it.

If the keypad buttons work tehn the Comfort bus should be working. Check the bus monitor when yoiu press a keypad button, each keypad button should be displayed
iN THE BUS monitor uncheck Filter Polls to see all the pollinmg and null reply, this will ensure that the keypad and scs on the bus are being polled
RE: Upgrade CM9000 to CM9001/A - cc_uk - 06-17-2026
These are the results of my testing:-
CM9000 on 8.030 firmware
SCS works - both buttons & temperature sensor
Keypads work
Bus monitor works and shows SCS button presses and keypad button presses
CM9001/A on 8.034 firmware
SCS - temperature sensor works, but buttons do not - they generate no events in Comfort and a response to control the LEDs does not change the LED state
Keypads work
Bus monitor does not work - after starting no activity is displayed, yet bus is clearly working.
Therefor for me, there also seems a problem with Bus monitor and the CM9001/A FW:8.034
8.030 isn't available for the CM9001/A so I tried with 8.031 - same result no output on Bus monitor and SCS buttons do not work
Some extra information that might help with this - if the ETH03 module is installed directly onto the CM9001/A - bus monitor does not work, however if the ETH03 module is moved to an a separate UCM connected to the CM9001/A - bus monitor does work, and shows responses when the SCS buttons are pressed.
I wanted to try an older firmware to see if this used to work, and ran into problems with that - I'll start a separate thread about that, rather than divert this one.
RE: Upgrade CM9000 to CM9001/A - slychiu - 06-18-2026
The Bus Monitor only works when connected to a UCM. If the ETH03 is connectedto Comfort, themn Bus monitor does not work because there is no RS485 bus to monitor. So with the Bus monitor runin g on UCM/ETH03, it cvan detect SCVS button presses? Can you copy the mbus monitor output when you press buttons
?
RE: Upgrade CM9000 to CM9001/A - cc_uk - 06-18-2026
Yes that is right - on the CM9001/A if the ETH03 is on the external UCM and I use bus monitor I see the SCS button presses, but the CM9001/A doesn't respond to them.
I can share the output once I solve the firmware issue on the CM9001/A
