As CAN Bus specifications are diverse, drivers for the
existing hardware must be tailored to the specific

Event
The RT-3020M also can utilize an event input pulse to
synchronize any external incident that requires precise
GPS time tagging, such as aerial photography. In this
case, the action of a camera’s aperture would output a
pulse to the
Event port and have the receiver output
position and time information relative to when the
photograph was taken.
Specifications:
- 50 Ohm input impedance
- 3Vdc > Input Voltage, High < 6Vdc
- 0Vdc < Input Voltage, Low < 1.2Vdc
- Minimum pulse width, 100nsec
- Rising or Falling edge Synchronization
Connecting the shared EVT MKR/CAN BUS port
requires a five core, 5mm diameter, cable fitted with a
LEMO plug, type FGG.0K.305.CLAC50Z, plus strain
relief, NavCom P/N 94-310062-3003.
