Preston MDR 2 to RED camera cable pinout specifications
17 years old. Gear and prices may have changed since.
What the thread found
- The RED camera uses a Lemo 1B-310 connector with pin 1 as ground, pin 5 as record trigger input, and pin 8 as RS232 receive data.
- The Preston camera run connector is a Lemo 2B-312 with pin 1 as ground, pin 3 and 4 carrying the run signal at 30mA maximum, and pin 9 and 10 for RS232 communication.
- A direct pin-to-pin connection approach was suggested for interfacing the two systems, with ground pins aligned.
Depends on
- The discussion does not provide explicit confirmation of the correct complete wiring scheme between Preston and RED connectors.
- No information about voltage compatibility or current limitations when cross-connecting systems is detailed.
- This appears to be from 2009 and may not apply to current RED camera models.
