The D IN/PPS port on VBOX Touch can be connected to a Handheld Start/Stop Logging Switch (RLVBACS010). The switch can then be used to control the logging on the unit.
This is a latching trigger switch where unlatched starts the logging and latched stops the logging.
Continuous Logging Mode should be selected when using the switch. It is connected to the 3-pin Digital In and PPS Connector on the side of the VBOX Touch.
When the trigger switch is connected and latched, it is not possible to use the SD Card Icon to manually start or stop logging data.
