What the thread found

• The Seitz 8700 system uses a 9-pin D-connector with specific pin assignments for power, ground, camera run signals, and three channel signals.
• Pin 4 and Pin 7 both supply 12 volts DC, with Pin 4 for general power and Pin 7 specifically for powering the amplifier.
• Pin 3 provides ground connection using black 24 AWG wire.
• The receiver can be powered independently by providing 12 volts DC and ground through the appropriate pins of the 9-pin D-connector without requiring a Steadicam IIIA unit.
• A custom cable or adapter box matching the pinout of the original IIIA connector can be engineered to power and operate the 8700 receiver standalone.

Depends on

• The technical manual for the Seitz 8700A was described as vague regarding connector specifications, using general descriptions rather than detailed pinouts.
• The Seitz company did not service these units after discontinuation and did not publish detailed customer-accessible documentation.
• The pinout for Lemo signal cables used in the system was not documented in available sources at the time of discussion.
• This discussion centers on 8700 and 8700A models from the early 2000s era.
