3.1.7 Serial port 2
This is the auxiliary serial port, and primarily used for the reception of RTCM SC-104 DGPS
(Differential GPS) correction messages.
3.1.9 Antenna connector
The antenna provided with this development kit should be connected to the SMA connector
located on the rear panel of the development unit.
3.1.10 DC power input
The supplied DC power adapter is to be plugged into the DC connector on the rear panel of
development unit. The development unit will accept voltages from 9 to 16 VDC. The middle pin
on J1 is negative polarity, while the outer shell is positive.
3.2 Configuration DIP switch
A typical setting of the Configuration DIP switch is shown in Figure 3-2.

Figure 3-2 Configuration DIP switch
Table 3-1 outlines the available functionality and corresponding switch position for the
Configuration DIP switch.
Switch Description Typical setting
1 GPIO3/GYROIN* OFF (high)
2 GPIO15/FR* OFF (high)
3 Serial BOOT OFF (normal run)
4 GPIO1/W_TICKS* OFF (high)
5 RTC BACKUP POWER ON (enabled)
6 PREAMP power select OFF (3 V)
7 PREAMP power select OFF (12 V)
8 PREAMP power enable ON (enabled)
* These functions have been disabled by internal switch
SW3 to allow correct operation of the antenna current sense
circuits on the Jupiter 30 adapter board.
Table 3-1 DIP switch settings
A brief description of the functionality of each switch is specified below. Refer to the Jupiter 30
Data sheet for more information about the functionality of specific pads. The receiver
operating settings will not change after moving the position of a configuration switch while the
development unit is operating. Pressing the reset switch, or turning the unit off and on will enable
the settings to take effect in the receiver. The recommended method for reconfiguration is to
switch the unit off, modify the switch positions, then re-apply the power.
3.2.1 DIP switch 1 – GPIO3 /GYROIN input
DIP switch 1 interfaces with the GPIO3 /GYROIN pad of the module. The switch is typically
off, but has no effect with the standard module’s software. This switch can be enabled by the
internal switch SW3.1.
3.2.2 DIP switch 2 – GPIO15 /FR input
DIP switch 2 interfaces with the GPIO15 /FR pad of the module. The switch is typically off, but
has no effect with the standard module’s software. This switch can be enabled by the internal
switch SW3.2.
