Connector provides high-current (up to 0.5A) dc-coupled 5V output and optoisolated I/O. When optoisolated pair is used used as an input (common use), external signal is applied between XSYNC1 (+) and XSYNC2(-). When the pair is used as an output (less common), external 5V power source should be connected in series with the receiver and 103891, so that "+" will be applied to XSYNC2, and "-" - to XSYNC1 (opposite to the input mode). Details are available in the circuit diagram of the 10389 board.
Output synchronization can be just a pulse or carry additional timestamp data when used to synchronize multiple NC393 cameras. See Trigger_393 for the settings.
| Name | Pin | Cable wire color | Description |
| XSYNC1 | 1 (D) | black | optoisolated, "+" input with respect to XSYNC2 |
| SYNC_DRV | 2 (A) | red | Sync output (DC-coupled), +5V pulses with respect to GND |
| GND | 3 (B) | white | Output reference, connected to the camera system ground |
| XSYNC2 | 4 (C) | green | optoisolated, "-" input with respect to XSYNC1 |
