Announcements

We have had reports that some (but not all) devices with old V1.17 firmware have lost their PAR calibrations when updating to V 2.036 or above. We are looking into this issue, and are testing a fix, which we will release as soon as possible. It is pretty clear, though that once the devices are recalibrated there should be no issues, Meanwhile, if you have a device with V1.17, hold off on updating until the fix arrives. 

This message is also on the Forum.

Thanks!

Dave, thanks for posting this announcement.

A way for users to test if they have this issue is to take a quick PAR measurement under full sunlight. If your the PAR intensity is greater than 2200 umol/m^2^/s, then your PAR calibration may have been lost as a result of the firmware update.

We have checked our device and calibration is also lost. We don't have the light box readily available to recalibrate the device, are there any other ways? Also, is there a way to go back to V1.17?

Hi Yulia,

Yes, I have a fix for devices like these. I tested it over the weekend on some of our devices, and it seems to work.

However, you will need to update your firmware, which is not a problem, and use the latest Desktop App. I understand that we can send you and IMG for the new Desktop App for macOS, but we are waiting for a security certificate for the Windows version. Hopefully that will come very soon.

Thanks,

Dave

All, We have a fix for the PAR calibration issue! Craig tried it and it seemed to work. We will post instructions shortly. Dave

I re-calibrated my devices using a LiCor PAR sensor. It was a good exercise as it helped me understand how these devices work.

Hi Milan! I WILL give you some good news! The only issue we have had was the potential loss of calibration data. We now have a new firmware/protocol combo that gets around this! We are finalizing these and testing to be sure that they work on all the different firmware versions.

I suggest we try it with yours. Can you tell me what the current firmware version for your device(s) are? then, I can step you through it.

Best, Dave

We have 4 devices with 1.23 and two with 2.0038 (they are sometimes not working because of that firmware I think...) Thanks for any help..Now we are trying to start again the big experiment and need all 6 devices I have...Kind regards... Milan

Can I even manually upload older firmware...to go back to version 1.23? If yes, where can I get the older versions of firmware?

Hi Milan,

Your calibration data was lost, so going back to 1.23 will not correct the problem. You will probably need to re-calibrate the instruments. The process is not difficult, but you will need a PAR meter and a uniform light source. The photosynQ team should either post instructions on the help documentation or contact you to help you though the calibration process.

Craig...thanks very much!!! Yes..i have PAR...BUT I AM DESPERATELY WAITING FOR SOME PHOTOSYNQ TEAM intervention...After they turned to be a "private company" the communication with them is worse day to day! This is not what I am calling a good productive collaboration. I need to bag them on the knees to send me some answer, but it is not comming. What else should I do?

Hi Milan,

Sorry to hear you are experiencing problems, especially with our support service. Unfortunately, I do not see a support ticket from you, so the support team may not have been notified about this issue. Please send a ticket to help@photosynq.org. I will be happy to arrange a video call meeting and personally walk you through the steps to recalibrating PAR, or any other issues that may be of concern.

Thank you

All,

Two important updates: First, we have been working on ways to update from old to new firmware without losing calibrations. This will work on most calibrations and from most firmwares. We are testing it across devices to make sure it will give you what you expect.

Second, we are also testing a small device that automatically calibrates PAR sensors and LED outputs.

One issue we have had is that we have been trying to be as backward compatible as possible to allow people to use older protocols. After the next firmware update, which should work on all previous protocols, we are going to start migrating everyone to the better protocol routines.

In the meantime, we will post a detailed instructions on how to tune up your devices.

Thanks, Dave
