Dual Deployment™ Controller

DDCS2 - Price: $69.00 - Includes CAB5/6-24 Interconnect Cable and GP-23A Battery.
The DDCS2 is a Dual Deployment Controller™. It has two altitude controlled deployment outputs that are typically used to fire deployment charges, based on altitude. The DDCS2 uses the same circuitry as the ALTS2 / ALTS2-50K Altimeter and handles Dual Deployment™, but it does not report maximum altitude after a rocket flight. Because of this, the tedious calibration requirements of the ALTS2 / ALTS2-50K can be avoided somewhat and allow the DDCS2 a substantially lower price. The DDCS2 can be used as the primary deployment controlling device if you don't care about measuring altitude (some rocketeers actually don't). But typically it would be used as a redundancy backup device alongside an ALTS2 / ALTS2-50K (or any other altimeter).
The first charge fires when the rocket reaches its maximum altitude (apogee), and the second charge fires when the rocket descends to 1200 feet or 600 feet or 300 feet above ground (3 choices, user selectable). One common usage is to deploy a main parachute at apogee by using only the first output. However, the most typical usage is to deploy a drogue chute or streamer first, then to deploy a main parachute when the rocket descends to 1200 or 600 or 300 feet above ground (Dual Deployment™), in order to avoid significant drifting due to wind.

Shorting Jumpers are used to connect two connecter pins together in order to turn on the power for some of the Adept devices. Shorting Jumpers are also used on some devices to program certain values or functions. One jumper is used on the DDCS2 to program the value for the Second Output Function, the output that fires the Deployment Charge for the Main Parachute.

Electronic Instrumentation is not compatible with the corrosive fumes and residue created by rocket motors and deployment charges. Seal holes and gaps in bulkheads and such with epoxy or removable putty.
The perfect mate for the DDCS2 when used in a dual redundancy backup system is the ALTS2 / ALTS2-50K. The ALTS2 / ALTS2-50K would function as the primary device to measure altitude and to control Dual Deployment™. The DDCS2 would function as the redundant backup device to also control Dual Deployment™.
