Comment
Emulated
Radar (ER)
Output
0VDC to VBATT+
Use the
RADARCONFIG
command to configure ER.
Emulated Radar pulses are output through the
Interface Cable (Optional Accessory)
on the next page 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
MARKTIME logs and ONMARK trigger.) Polarity is configurable
using the
MARKCONTROL
command.
