CP540 Error Message

Pro Timing is currently working with Sam to get the CP 540 back in operation again.

Remove batteries, reinstall batteries, press reset button with unfolded paper clip.

Try to restart, if ok proceed.

If not then updating the firmware using the two step process is needed. The older bootloader has to be used first, then the newer.

This can be done on site but it is better to return the unit to our service centre. 

During my last race the CP540 (system B) died... I was unable to restart it.

I removed the batteries and wait till the next weekend, than I replaced the batteries and resetted the timer. It restarted normally...

Now, do I need to update the firmware? Actual version is D-05...
Can it helps to avoid unwanted shut off?

Thanks for you advise

Hi all! thanks for sharing your experiences regarding this issue

I removed the AA batteries for 3 days, and reseted it many times, even pressing the reset button in the back.  I tried to update firmware and it was unable to accept the firmware.

By the way, the screen never shows any character or light, only the printer says:

FWT Timeout 1
FWT Timeout 2 6
FWT Timeout 0 ...

Is there any method to revive the unit?
Is there a proven firmware that is better to avoid this issue?

any help is highly appreciated.

regards,

Hi! seems I have same problem than @jygregoire ("FWT Timeout 1..." error on the paper roll, with no other information).

I have removed the batteries, have pressed reset button many times, and I think the version on the CP540 is D-05. Did anyone solve this issue? any recommended firmware, update manager or bootloader version?

Thanks so much for your support, dudes

hope anyone could solve this FWT error.

by the way I found this pdf which covers the serial protocol  among a PC and a CP540.
extended cp540 user manual pdf

I will try to debug the responses of the unit in a low level serial sniffer in order to give more details of this error, as I still can't make this unit lives again.

cheers.

Just to facilitate more information (following command set in above pdf):

Even though the CP540 is printing "FWT Timeout 0 ..." error, I can communicate my PC with the unit with "#ID" commands and even with "#PL ANY_MESSAGE" and printing on the paper the "ANY_MESSAGE", so I conclude the unit can still communicate (with correct bauds and RS232 config) but not to enter in the normal behaviour. I attach the image showing the ID of my unit and other info.

Is there any other debug command to detect which part of the hardware/firmware could be wrong?

On the other hand:

When I try to burn VC02 firmware it gets always stuck in the "Download not Fully Completed" in the “Downloading Keyboard Firmware" stage.

cheers!

I had the same problem and I solved it by changing the internal battery (CR 2032) of the 540

Changing the battery is a good idea. As these timers age the battery will fail and the memory of settings be be lost between uses. The battery is located in a holder under the keypad. You have to disassemble the entire timer to get to that spot.
