This setting controls the Main deployment channel. This channel is typically used to deploy the
large “main” parachute, at a pre-programmed altitude after apogee. When set to “0”, the channel
is turned off, and will not fire. The altitude and elapsed time of Main deployment are recorded in
the Flight Summary memory for downloading. Zeroes in these fields means that the Main
channel wasn’t enabled and therefore didn’t fire.
B Drogue <0-Off,1-Drogue,2-Backup>
This setting controls the Channel B deployment channel. When set to “0”, the channel is turned
off. When set to 1, the deployment channel turns on at nose-over, 1 second after apogee. If set
to 2, it works the same as “1”, except that the channel turns on TWO seconds after apogee rather
that ONE second after apogee (at nose-over). This allows you to configure an Eggtimer TRS in
your rocket to be a “backup” unit, so that a second drogue charge can be fired slightly later than
the primary, for redundancy. In a backup configuration, you’d also configure the main channel
to fire about 100’-200’ below the primary, depending on the altitude that you had the primary set
to.
