Input/ Factory
Output Default
Input Active low An input mark for which a pulse greater than 150 ns
triggers certain logs to be generated. (Refer to the
Leading MARKPOS and MARKTIME logs and ONMARK trigger.)

Polarity is configurable using the
triggered
command. The mark inputs have 10K pull-up resistors to
3.3 V

Output Active Indicates a valid GNSS position solution is available. A high
high
level indicates a valid solution or that the
command has been set. VDD is 3.3 V
Output Active low A programmable variable frequency output ranging from
0 – 100 MHz (refer to the
Input Active low Reset LVTTL signal input from external system; active low,
50 ms duration
Output Active low 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
