Main Page → Motive Documentation → Synchronization → Custom Synchronization Settings: OptiHub
This page lists out the custom synchronization settings under the Synchronization pane when using the OptiHub.
To customize sync settings when using the OptiHub or the OptiHub 2, change the Sync Mode to Custom Synchronization. Using this mode, users can configure the master sync source of the camera system as well as the output signals from the hub for triggering other external acquisition devices.
For general instructions on customizing sync settings when integrating external devices, read External Device Sync: OptiHub guide.
Difference Between OptiSync and Wired Sync
To setup the sync input signals, first define a input Source and configure desired trigger settings for the source:
The Internal/Wired input source uses the OptiHub's internal synchronization generator as the main sync source. You can modify the synchronization frequency for both Wired and OptiSync protocol under the Synchronization Control section. When you adjust the system frame rate from this panel, the modified frame rate may not be reflected on the Devices pane. Check the streaming section of the status bar for the exact information.
The Sync In input source setting uses signals coming into the input ports of the OptiHub to trigger the synchronization.
Input Trigger: Can select from Either Edge, Rising Edge, Falling Edge, Low Gated, or High Gated signal from the connected input source.
Input Divider: Allows a triggering rate compatible with the camera frame rate to be derived from higher frequency input signals (e.g. 300Hz decimated down to 100Hz for use with a V100:R2 camera). Valid range is 1 (no decimation) to 15 (every 15th trigger signal generates a frame).
(The camera system will be the slave) sets an external USB device as the sync source. This mode is for customers who use the Camera SDK development kits and would like to have their software trigger the cameras instead. Using the providede API, the OptiHub will be send the trigger signal from the PC via the OptiHib's USB uplink connection to the PC.
Input Trigger: Determine which input trigger is used for synchronization. Either Edge, Rising Edge, Falling Edge, Low Gated, or High Gated.
USB Sync-In Control: Only available if Source is set to USB. Allows the user to allow or block trigger events generated by the internal sync control. This option has been deprecated for use in the GUI. Valid options are: Gate-Open and Gate-Closed.
Input Divider: Only available if Source is set to External Sync. Allows a triggering rate compatible with the camera frame rate to be derived from higher frequency input signals (e.g. 360Hz decimated down to 120Hz for use with a Flex 13 camera). Valid range is 1 (no decimation) to 15 (every 15th trigger signal generates a frame).
Sync signals can also be sent out through the output ports of the OptiHub to slave devices in the synchronization chain.
