Telemetry or alarm bug?

Hi Jeti / all.

I have found a problem with "displayed telemetry", or rather, with "low voltage alarm".

My system is: Transmitter: DS16 (with latest FW) / Receiver: CB200 / accu: 2x 2S LiFe.

In the picture "screen001" can be seen the telemetry info I have chosen. The image "screen002" shows the "problem".



"Voltage Rx" does not show / measure the correct voltage, but the telemetry from the CB does (see "screen002").

The problem comes when I have to set a "low voltage alarm", because it uses "Voltage Rx", which does not measure properly.

I just don't know whether it is the CB or the DS16 that has the 'error'....

There is no problem. One is the voltage of the battery and one of the receiver. And they are different, that's correct.

Hi Jochen.

I understand.

But the "low voltage" alarm is suppose to avoid too low voltage on the batteries. Why is it then it measures the voltage of the CB?

If I'm using this alarm, how am I going to find the value to use, so it warns me when the battery is at 6,2 volt?

The input range of the CB is 3,5 to 15 volt, but the battery (the one I use) only works from 6,7 to 6,2 volt. Even a empty 4s NiMH is higher than the lower limit of the CB. Why then even look at the CB. It is the battery that is "the weak spot" in this 'equation'.

Am I talking sense or am I completely wrong....?

Hi René,
you can use both. The voltage of the receiver is always 0,5 V lower than the highest battery-voltage. That means you can use two different batteries (or one BEC and one battery) ans set alarms for every battery and you can additional to this use an alarm for the Receiver-voltage. I´ve configured all three Alarms (and additional an alarm for capacity of the battteries)

Best regards
Jochen

Hello Rene,
in the CB is a diode in the Rsat supply path to prevent reverse supply of the CB when connecting a battery to RSat.
And therefore the RX voltage is typ. 0,5V lower than the supply voltage in CB.
