mPCIe interface or the I/O cable. The tamper signal trigger mode and FW upgrade can also
be selected by user.
Figure 6: Onboard DIP switch
Please note that the in SW1.1 to SW1.6, the OFF position actually disconnects the
power/signal from the mPCIe pin, while the ON position ties mPCIe pins and I/O cable pins
together. In order to avoid interference and to keep 5V power from damaging your system
board, it is important to set the DIP switch to correct positions before connecting the I/O
cable.
Switching of internal/external GNSS and 1PPS signal is not controlled by DIP switch.
