3.6 OEM interface connector
The OEM communications interface is a dual
row, straight 2x10 pin field connector header. The
pins are spaced on 2.0 mm centres and the pin
lengths are 7.8 mm (0.3 in) off the board surface
with 2.3 mm at the base for plastic form. Figure
3-2 diagrams the 20-pin I/O connector and shows
the pin 1 reference location. The mating female
connector is an IDC receptacle. See table 1-1 for
antenna connector options.
3.7 Mechanical layout
The mechanical drawing for the Jupiter board is
shown in figure 3-3.

3.8 ESD sensitivity
The Jupiter GPS receiver contains Class 1
devices. The following Electrostatic Discharge
(ESD) precautions are recommended any time the
unit is handled:
• protective outer garments.
• handle device in ESD safeguarded work
area.
• transport device in ESD shielded
containers.
• monitor and test all ESD protection
equipment.
CAUTION: treat the Jupiter receiver as extremely
sensitive to ESD.
