Default
An input mark 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. The mark inputs have 10K pull-up resistors to
Active
3.3 V
low
Note: Event1 is the default behavior for pin 9 of
connector P1701. The secondary behavior for pin 9 is
COM3_Tx. If COM3 is enabled, the Event1 input is
disabled.
An input mark for which a pulse greater than 150 ns
triggers certain logs to be generated (see the MARK2POS
and MARK2TIME logs). Polarity is configurable using the
MARKCONTROL command. The mark inputs have 10K
Active
pull-up resistors to 3.3 V
low
Note: Event2 is the default behavior for pin 7 of
connector P1701. The secondary behavior for pin 7 is
CAN1Tx. If CAN1 is enabled, the Event2 input is disabled.
A time synchronization output. This is a pulse where the
Active leading edge is synchronized to receiver-calculated GNSS
low Time. The polarity, period and pulse width can be
configured using the PPSCONTROL command
Active
Indicates a valid GNSS position solution is available.

P1701. The secondary behavior for pin 6 is CAN1Rx. If
CAN1 is enabled, the VARF output is disabled.
