Timing and Sync Custom Devices

Last Modified: March 24, 2021

A timing and sync custom device is any device that has the capability to drive the RTSI 0 line to serve as the chassis master hardware synchronization device for a system.

The RTSI 0 line is a digital line that sends a clock signal to synchronize all hardware I/O devices in the system. You can plan and build a timing and sync custom device from a LabVIEW project. You must modify the VIs of the project to conform to the custom device framework and build the device for distribution to VeriStand.

When you distribute the device, operators can add the device to VeriStand by copying the contents of the Build directory you create into the <Common Data>\Timing and Sync directory on their host computer. VeriStand parses this directory for timing and sync devices when it launches.

After an operator has added the custom timing and sync device to the directory, they can add the device to the system definition file and configure the device as the chassis master hardware synchronization device. Timing and sync devices appear in System Explorer under Hardware»Chassis»Timing and Sync.
