Properties Pane: eSync2

Last updated
By modifying the device properties of the eSync, users can customize the sync configurations of the camera system for implementing various sync chain setups.
While the eSync is selected under the Devices pane, use the Properties pane to monitor the eSync properties. Here, users can configure the parent sync source of the camera system and also the output sync signals from the eSync for integrating child devices (e.g. NI-DAQ). For a specific explanation on steps for synchronizing external devices, read through the following page: External Device Sync Guide: eSync 2.
Configure the input signal by first defining which input source to use. Available input sources include Internal Free Run, Internal Clock, SMPTE Timecode In, Video Gen Lock, Inputs (input ports), Isolated, VESA Stereo In, and Reserved. Respective input configurations appear on the pane when a source is selected. For each selected input source, the signal characteristics can be modified.
Synchronization Input Source Options
Internal Free Run
This is the default synchronization protocol for Ethernet camera systems without an eSync2. In this mode, Prime series cameras are synchronized by communicating the time information with each other through the camera network itself using a high-precision algorithm for timing synchronization.
Internal Clock
Sets the eSync 2 to use its internal clock to deliver the sync signal to the Ethernet cameras, and the sync signal can be modified as well.
SMPTE Timecode In
Sets a timecode sync signal from an external device as the input source signal.
Video Gen Lock
Locks the camera sync to an external video sync signal.
Isolated
Used for generic sync devices connected to the Isolated Sync In port from the eSync 2. Considered safer than other general input ports (Hi-Z and Lo-Z). The max signal voltage cannot exceed 12 Volts.
Inputs
Uses signals through the input ports of the eSync 2. Used for high impedance output devices. The max signal voltage cannot exceed 5 Volts.
VESA Stereo In
Sets cameras to sync to signal from the VESA Stereo input port.
Reserved
Internal use only.
Controls the frequency of the eSync 2's internal sync generator when using the internal clock.
Introduces an offset delay, in microsecond, to selected trigger signal.
Sets the trigger mode. Available modes are Either Edge, Rising Edge, and Falling Edge, and each of them uses the corresponding characteristic of the input signal as a trigger.
Allows a triggering rate, compatible with the camera frame rate, to be derived from higher frequency input signals.
Allows a triggering rate, compatible with the camera frame rate, to be derived from lower frequency input signals. Available multiplier range: 1 to 15.
Displays the final rate of the camera system.
eSync2 ports vs eSync ports
In the eSync2, three general input ports are implemented in place of Lo-Z and Hi-Z input ports from the eSync. These general input ports are designed for high impedance devices, but low impedance devices can also be connected with appropriate adjustments. When the eSync 2 is connected to the system, options for Lo-Z and Hi-Z will be displayed.
Lo-Z input: Sets an external low impedance device as the trigger. The max signal voltage cannot exceed 5 Volts.
Hi-Z input: Sets an external high impedance device as the trigger. The max signal voltage cannot exceed 5 Volts.
Allows you to configure signal type and polarity of synchronization signal through the output ports, including the VESA stereo output port, on the eSync 2.
Type: Defines the output signal type of the eSync 2. Use this to sync external devices to the eSync 2.
Polarity: Change the polarity of the signal to normal or inverted. Normal signals constantly output a low signal and pulses high when triggering. Inverted signals constantly output a high signal and pulse low when triggering.
Output Signal Types
Exposure Time
Outputs a pulse signal when the cameras expose.
Recording Gate
Outputs a constant high level signal while recording. Other times the signal is low.
Record Start/Stop Pulse
Outputs a pulse signal both when the system starts and stops recording.
Gated Exposure Time
Outputs a pulse signal when the cameras expose, when the system is recording.
Gated Internal Clock
Outputs the internal clock, while the system is recording.
Selected Sync
Outputs the Sync Input signal without factoring in signal modifications (e.g. input dividers).
Adjusted Sync
Outputs the Sync Input signal accounting for adjustments made to the signal.

SMPTE Timecode In
Video Genlock In
Isolated
Inputs
VESA Stereo In
Reserved
Uses a selected input signal to generate the synchronization output signal.
Trigger Source: Determines which trigger source is used to initiate the recording in Motive. Available options are Software, Isolated, and Inputs. When the trigger source set to software, recording is initiated in Motive.
With the eSync 2, external triggering devices (e.g. remote start/stop button) can integrate into the camera system and set to trigger the recording start and stop events in Motive. Such devices will connect to input ports of the eSync 2 and configured under the Record Triggering section of the eSync 2 properties.
By default, the remote trigger source is set to Software, which is the record start/stop button click events in Motive. Set the trigger source to the corresponding input port and select an appropriate trigger edge when an external trigger source (Trigger Source → isolated or input) is used. Available trigger options include Rising Edge, Falling Edge, High Gated, or Low Gated. The appropriate trigger option will depend on the signal morphology of the external trigger. After the trigger setting have been defined, press the recording button in advance. It sets Motive into a standby mode until the trigger signal is detected through the eSync. When the trigger signal is detected, Motive will start the actual recording. The recording will be stopped and return to the 'armed' state when the second trigger signal, or the falling edge of the gated signal, is detected.
Note: For capturing multiple recordings via recording trigger, only the first TAK will contain the 3D data. For the subsequent TAKs_, the 3D data must be reconstructed through the_ post-processing reconstruction pipeline.
Open the Devices pane and the Properties pane to access the eSync 2 properties.
Under the Record Triggering section, set the source to the respective input port where the trigger signal is inputted.
Choose an appropriate trigger option, depending on the morphology of the trigger signal.
Press the record button in Motive, which prepares Motive for recording. At this stage, Motive awaits for an incoming trigger signal.
When the first trigger is detected, Motive starts recording.
When the second trigger is detected, Motive stops recording and awaits for next trigger for repeated recordings. For High Gated and Low Gated trigger options, Motive will record during respective gated windows.
Once all the recording is finished, press the stop button to disarm Motive.
