The RED START/STOP CABLE (1B TO SYNC, CTRL, BNC) provides start/stop and tally support through the RED W.M.D. (WIRELESS MOTOR DRIVER).
The 14-pin 1B LEMO connects to the EXP port on the W.M.D, and transfers the tally signal from the BRAIN to the W.M.D. The 4-pin LEMO connects to the CTRL port on the BRAIN.
The BNC connector connects to the SYNC port on the BRAIN via a 3BNC-TO-00 SYNC CABLE and a BNC-TO-BNC Adaptor, and transfers the start/stop signal to the BRAIN.
NOTE: Full support for start/stop requires the 3BNC-TO-00 SYNC CABLE and a BNC-TO-BNC ADAPTOR (included with the RED 3-Axis Lens Control System). The 3BNC-TO-00 SYNC CABLE has two additional BNC connectors that offer support for timecode and genlock.
