Input/ Factory
Output Default
Input Active An input mark for which a pulse greater than 150 ns triggers
Leading low certain logs to be generated. (Refer to the MARKPOS and
edge MARKTIME logs and ONMARK trigger.) Polarity is
triggered
configurable using the
inputs have 10K pull-up resistors to 3.3 V
Input Active An input mark for which a pulse greater than 150 ns triggers
Leading low certain logs to be generated (see the MARK2POS and
edge MARK2TIME logs). Polarity is configurable using the
triggered MARKCONTROL
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 (refer to the
command). VDD is 3.3 V
Output Active A programmable variable frequency output ranging from
low
0 -5 MHz (refer to the
Input Active Reset LVTTL signal input from external system; active low,
low > 20 µs duration
Output Active A time synchronization output. This is a pulse where the
low leading edge is synchronized to receiver-calculated GNSS
Time. The polarity, period and pulse width can be configured
using
