CTRL (RS232 CONTROL)
The 4-pin 00B LEMO CTRL connector supports RS232 remote control for 3D camera communication and third-
party metadata ingest applications. For more information, go to “BRAIN GPIO” on page 107.
The General Purpose Out (GPO) tally presents 3.3 V at a maximum of 0.04 A between pins 1 and 3. When used
as a record tally, the rising edge of the pulse indicates start of record, falling edge represents end of record.
