Table 3-3 Utility connector pin out
In case you are using a +12V active antenna you must either have a +12V present
from the PC/104 bus or you can supply it through pin # 2 of the utility connector. The
+3,6V battery input pin # 7 may be used in case you do not use the onboard battery
for GPS SRAM backup. Do not supply this pin if the battery is connected. The 1PPS
and 10KHz outputs are buffered using HCT04 buffers. The SER_OUT signal present
in pin #3 is the TTL-level output of the GSP receiver. You may use this to connect to
other devices in your system that mat need GPS information.
