The Ultra 1 stage uses a 3-pin Lemo connector with pin 1 for ground, pin 2 for 13.2 VDC, and pin 3 for 28.8 VDC battery power.
The Ultra 2 stage uses a 3-pin Lemo connector with pin 1 for power ground, pin 2 for 12V battery (either direct or from DC-DC converter depending on mode), and pin 3 for 24V battery from two sled batteries in series.
The Archer stage is a 12V only system, making pin 3 of its power connector inoperative.
The matching Lemo plug designation for the Archer stage power output is FGG.OB.303.CLAD52.

Ultra designations may not match Archer exactly despite similar architecture.
Power ground and video ground connections depend on internal jumper settings on the control board.
The thread does not confirm the exact pinout for Archer, only extrapolates from Ultra models and notes that pin 3 is unused.
