Hi
I recently had to reload Windows Vista on my PC.
When I try to connect from the PC to Serial UCM, I get the following message :
Failed to write to UCM
I am using Config 3.0.1.0 (have the same problem with previous versions)
I have a third party device connecting to the UCM with no problems.
Any ideas ?
Thanks

You have the same problem with previous Comfigurator versions, does it include Comfigurator version 2.2.3?
Mind to tell us more on how do you determine that the third party device can work with the UCM?
What are the UCM and Comfort firmware versions?

Yes

Cause I can send commands to Comfort from Control4 and it responds, eg Security Off, Arm etc
What are the UCM and Comfort firmware versions?
Comfort Ultra II Ucm Version5.92

Try setting No Hardware Control on Comfigurator and remove SW8-H on the UCM to disable Hardware Flow control

Perhaps the problem is due to the Windows Vista on your PC if you say that you have had to reload it.
Try the UCM on another PC with Comfigurator and see if it works there

Just a thought but is Comfigurator and the other application tests both using the same TCP port? Could also explain why one works and one doesnt if they are different?
I just thought maybe that in reloading Vista that it might be something to do with the firewall on the PC and it is blocking some TCP ports? You could try temp disablig the firewall and see if that changes the symptoms.

Hi
Tried turning off firewall and still no joy.
Comfig acknowledges that COM1 exist and ask for a password but beyond that \'No response from UCM\'. Does complain when I use COM3.
If I did a complete reinstall (new HD) would I need to install the drivers for the motherboard ?
I tried another computer using a USB to serial cable, same issues
Thanks

If you were able to connect a third party to the UCM, then the UCM musr be workjing. The problem may be related to your PC or IS
If you have tried connecting to another computer with a serial to USB cable check the COM port assigned as this may change whenever you plug it in Check the port using Control Panel > System > Hardware
Use Hyperterminal as described in the UCM Manual to try to connect and logiin
Check that the D9/D10 Leds are both blinking
Look at the D11/D12 red/green leds
When you send from the PC, you should see the green led D12 blink so if it does not the UCM is not receiving anything at all
When the UCM responds you should see D11 blink
