Add camera's input voltage reading from QHY cameras?

Voyager Feature Requests
1

There have been recent discussions in Cloudy Nights forum about Under Voltage Lock Out (UVLO) in QHY cameras. If QHY has capability of measuring the input voltage of their cameras and if it can transmit voltage readings over USB cable, would it be possible for Voyager to capture the voltage reading and display maybe in “Camera Config” window in Camera Setup or in one of the existing Status boxes of Status Window? I hope it’s already part of SDK development that you don’t have to do much work.

I’ve been getting a few UVLO and that then prevents from the camera to cool higher than 70% cooling capacity. In order to reset the UVLO flag, I have to run QHY EZCap software to reset UVLO flag. It sometimes drives me crazy.

It would be nice to watch the voltage reading somewhere on Voyager’s screen continuously and see if it’s dropping for any reasons before UVLO triggers.

This would probably only work for QHY native drivers, because ASCOM drivers most likely don’t support capturing camera’s input voltage readings.

Thanks,

Hi Peter,

not interested in this kind of features. Voyager is an automation software for unattended imaging.

I realized Voyager is an automation software but it would be nice to have some small and useful features added. Oh well, thanks for responding.

As an electronic engineer I am perplexed, and it is an understatement, in front of certain things. I always respond when I can and try to keep things on track that makes sense.

Several people including myself at other forums experienced UVLO in QHY cameras and I thought it would be helpful to monitor the camera’s input voltage and if it shows less than 11V, it could trigger UVLO and we can test our power supply. If the power supply still provides minimum required voltage, then I can report this findings to QHY.

I’m not pressuring you in adding this feature. Just providing information and it’s up to you to decide, not me.

BTW, I’m also a retired electronic engineer.

Hi Peter,

the answer is the same sorry. I understand but the right pressure to do would be elsewhere to others and not on Voyager.

All the best

I just found out somebody already asked Dr Qui of QHY the same question I asked you. He said that there is no voltage level measurement. The VRM (voltage regulator module) has a pin that signals a low voltage condition and that’s how the mainboard’s FX3 GPIF knows that there’s trouble in that neighborhood. So, it can know if the voltage is too anemic, but not necessarily what the voltage level is.

So it wouldn’t be possible to gather voltage measurements from QHY cameras.

Thanks for your time and patience.
