This document provides detailed guidelines for the operation and conguration of the Jupiter
30 GPS Module Development Kit. The AA003029 series of development kits assist in the
integration of the Jupiter 30 in a customer’s application, offering a simple and easy to use
platform for evaluation purposes.
It is recommended that the user pays particular attention to the conguration settings outlined
in section 3.0 prior to applying power and operating the development unit. For example, it is
important to understand and recognise the main functional switches and connector locations
accessible on the development unit’s front and rear panels. Following this information, simple
step-by-step guidelines are presented to ensure successful setup of the development unit.
In addition to hardware, the GPS Development Kit is supplied with SiRFDemo and SiRFash
analysis software to allow communication with the Jupiter 30 GPS receiver through a serial port.
The Windows based software presents the receiver’s raw data in a geographical form, allowing
both detailed analysis and evaluation for both NMEA and SiRF Binary formats.
2.0 Equipment
This section provides a brief overview of the equipment included in the Jupiter 30 GPS
Development Kit.
2.1 Equipment supplied
This kit should contain the items illustrated in Figure 2-1.
1. Jupiter 30 GPS development unit
The Jupiter 30 GPS receiver development unit includes all of the following hardware to allow
thorough evaluation:
• Dual RS232 level serial data I/O ports
• Selectable bias voltages for active GPS antennas
• Backup power source for SRAM and RTC
• Provision to insert a current measuring device to monitor both primary and backup power
usage under various conditions
• Regulated DC power supply to the Jupiter 30 module
• Status indication through four LEDs on front panel
• Congurable functionality using a DIP switch accessed through the front panel

A magnetic-mount active antenna is supplied with the receiver development kit, along with an
RF cable (RG-316) already terminated with the proper connector for the development unit. The
nominal measured attenuation of the cable with connectors is approximately 5 dB. The supplied
active antenna should be biased at +3 VDC, but a different active antenna with a bias of either
+3, +5 or +12 VDC may be used. Refer to section 3.2 to ensure that the conguration switches
on the front panel of the development unit are chosen to select the appropriate bias voltage.
Caution: ensure antenna power switches are properly set before connecting the antenna. An
antenna designed for +3 VDC operation will be damaged if connected to a +12 VDC
source.
3. Serial interface cable
A serial cable is provided to interface between the development unit and the customer’s PC, or
between the development unit and a DGPS receiver. This cable is terminated at both ends with
female connectors to match the male connectors on the development unit and the PC. If the PC
used only supports a USB port, an RS232/USB converter could be utilised.
4. Power adapter for 240/120 VAC operation
DC power for the development unit is provided by either an AC/DC converter or automobile
adapter. The AC/DC converter operates from a nominal 120/240 VAC input and provides a
12 VDC at 500 mA out.
5. Power adapter for 12 VDC vehicle operation
For mobile operation, an automotive adapter intended for use in 12 VDC vehicles is provided.

6. Software and documentation CD
The CD contains the Jupiter 30 GPS receiver data sheet, PC Analysis software (SiRFDemo and
SiRFash), and other information on how to use GPS receivers.
2.2 Equipment required
The following equipment is also required to evaluate the Jupiter 30 receiver.
• IBM compatible PC
• Minimum one serial port (If your PC only has USB, a USB/RS232 converter can be
employed)
• Windows 95/98, WinNT4.0 or higher
• 486 100MHz or higher
• SVGA at least 800x600 resolution
• 16 Megabytes of RAM
• 6 Megabytes (min) of disk space
3.0 Technical conguration
This section provides a detailed description of all the technical aspects and congurable
functionality of the Jupiter 30 GPS development unit.
3.1 Overview
Figure 3-1 illustrates the connectors, switches and LEDs available on the development unit.
3.1.1 Power switch (On/Off)
The switch on the front panel controls primary power to the Jupiter 30 receiver module inside.
The power status LED (see section 3.3) indicates the state of the unit: if lit, the module has
primary power supplied. If the conguration DIP switch 5 is on and Jumper JB5/6 linked, the
module’s secondary supply SRAM and RTC will continue to be powered when the power switch
is off. Only the removal of the DC power input at the rear of the unit will stop secondary power
being applied (assuming Jumper JB5/6 and switch 5 are correctly set). Having this secondary
power supply applied means that the Jupiter 30 will have a ‘hot start’ capability when primary
power is re-applied within 4 hours, and a ‘warm start’ thereafter, by maintaining last position,
current time and satellite ephemerides.
3.1.2 Conguration DIP switch
The conguration DIP switch on the front panel provides the ability to congure the Jupiter
30 module, offering exibility depending on the specic application. Refer to section 3.2 for a
description of the functionality of each individual switch, including the typical settings when using
the Jupiter 30 module.
3.1.3 Function LEDs
The four LEDs on the front panel provide an indication of the current status of basic features
associated with the development unit. Refer to section 3.3 for a complete description of the
function of each LED.
3.1.4 Reset switch
A reset push button is provided on the front panel to generate a receiver system hardware reset.
3.1.5 Clock out connector
The Clock out connector, located on the rear panel of the development unit, can be used to
provide module generated timing signals. Refer to section 3.4 for more detailed information.
3.1.6 Serial port 1
This host serial port is used to send and receive serial data. This port is used as the default, with
transmission in NMEA format at the rate of 9600 Baud. The connectors to be used with these
serial ports are 9-pin D-subminiature connectors.
