View Full Version : Measurement rate miniBirds

02-18-2008, 12:30 AM
Hello Everybody,

I have a question regarding the Ascension miniBird system. Recently, we're
experiencing some problems with obtaining the right measurement rate. When
asking the Flock to measure with 100Hz instead of the 103.3Hz (the default
value) the rate drops to somewhere around 70Hz. This happens no matter
whether we use the Flock in group mode or in single mode with each bird
using a determined RS232 port. We didn't change anything in the set-up of
the system, which worked just fine before at 100Hz.
Further, we never got it really to work at 144Hz when using more than 2
birds. Has anybody any ideas about what kind of set-up is necessary to use
all birds with the full measurement rate?

Any suggestions would be highly appreciated.
