No Response from UCM05

[WMADKOUR]

i have a problem with UCM05, once a sudden it do not connect to cytech board, i tried another UCM05 and it made the same problem, every 15 trial it connect couple of times and then keep giveing me a msg \"No Response from UCM\"
the LED D9&D10 blinking properly and RDY steady as well !!

both UCM05 firmware V 7.008, comfort version 7.005 and connecting using cytech 4wire RS cable.
so any suggestion ?

Every 15 trials?
You mean that you login, logout, login, ... login from Comfigurator 15 times and the 16th times it gives \"No Response from UCM\" message?

What Comfigurator version are you using?
UCM05 means that you are using serial connection?

[WMADKOUR]

what i meant by connection: is \"system information\" check-up
and it is not exactly 15 times , but around
i\'m using latest configrator V3.6.8
yes i meant serial interface

This is probably a problem with the PC serial port
Are you using a USB to serial converter?
There may be intermittent problems with this type of converter

[WMADKOUR]

the serial-usb used to work fine before for a long time on the same operating system, even we tried a new one, but the same problem occurs.
is there is any way to test sort of communication ? like pinging or something like that, since the two ucm05 serial have the same issue.
thanks

Check the D11 (Green) and D12 (RED) LEDS

D11 (green) blinks if the UCM is receiving from the PC
D12 (red) blinks if the UCM is sending to PC

Log in on Comfigurator
When you send some info the D11 LED should blink, then the D12 Red led should blink when the UCM replies

If the D11 led does not blink that means that the data is not reaching the UCM, and that means your conection from PC to UCM is ot working
If D11 blinks but D12 does not blink that means a problem with UCM
