Hi,
I got a Profilux Light II used for 3-4 years, quiet a lots of missing segment found on the display, so I order one and replace it, but it can't recognize the temp probe ( its firmware version : 5.07 ), someone told me that I should down grade the firmware version to 4.X otherwise it can't recognize the temp probe, so I downgrade the version to 4.08 but still can't .....I have take another temp probe from my P3 but got same result .... so what should I do now :( ?

You don`t need to downgrade the firmware, in 5.xx the probe should be also present, of course.
What does "but it can't recognize the temp probe " mean exactly? Where is it missing?
What device type does the display show after booting?
Maybe the preprogrammed S/N is not correct, but this can be fixed.

Hi,
What does "but it can't recognize the temp probe " mean exactly? Where is it missing?
- After I replaced the display board, I can't find the "sensor setting" in the menu ( temp probe already plug-in ), so I connect the Light II to my computer and check by using PLC ( version 5.09 ), I can see the sensor overview but the temp probe appear as a level sensor...... After I downgrade the firmware, I can see the "sensor setting" in the menu but the temp probe or to be exact, no sensor found in the menu of Light II or check by using PLC ( version 4.08.1 ).
Maybe the preprogrammed S/N is not correct, but this can be fixed.
- What should I do ?
Regards,
Ricky

Since I already replaced with the old display board ( since I need Light II to control the chiller ), I will exchange the board again when I back home on Fri night. Any idea how long it will take to fix S/N problem so that I consider whether to replace the old board again or not ?
The no. shown on the label stick on the board is S/N ?

The S/N is printed on the label of the device.
If there is an issue with the S/N it can be fixed in a few minutes. I send you a PM how to do it.

Hi,
Just have time to replace the display board and complete the recreation of S/N so the temp. probe can be seen and set. However, when I doing the firmware update to latest version 5.10 or 5.12at "erasing flash" stage, error message pop-up,

so pls advise how to fix since I would like to use it to control AI nano ?
Existing firmware : 4.08
PLC : 4.081
Remark : with proper USB-serial adaptor and GHL serial cable; I never experience this problem when updating my P3 ex.
Thanks for any help !!!
