SMART2 Strobe Specifications

The SMART2 strobe signals are available on the 14-Pin Interface connector. Pulse Per Second (PPS) strobes provide synchronization signal.

Refer to SMART Antenna Interface Cable (Optional Accessory) for pin out details.

SMART2 Strobes Description

Strobes

Input/Output

Comment

Emulated Radar (ER)

Output

0VDC to VBATT+

Use the RADARCONFIG command to configure ER.

Emulated Radar pulses are output through the SMART Antenna Interface Cable (Optional Accessory) and the RADARSTATUS log.

PPS

Output

3.3V CMOS

A time synchronization output. This is a pulse where the leading edge is synchronized to receiver calculated GNSS Time. The polarity, period and pulse width can be configured using the PPSCONTROL command.

Mark Input (MKI)

(Event1)

Input

Voltage Input Low is 0.8V
Voltage Input High is 2V

Input marks for which a pulse greater than 150 ns triggers certain logs to be generated. (Refer to the MARKPOS and MARK1TIME logs and ONMARK trigger.) Polarity is configurable using the EVENTINCONTROL command.
