6. Software and documentation CD
The CD contains the Jupiter 30 GPS receiver data sheet, PC Analysis software (SiRFDemo and 

SiRFflash), and other information on how to use GPS receivers.

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

Figure 3-1 illustrates the connectors, switches and LEDs available on the development unit.

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 configuration 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.

The configuration DIP switch on the front panel provides the ability to configure the Jupiter 

30 module, offering flexibility depending on the specific 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.

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. 

A reset push button is provided on the front panel to generate a receiver system hardware reset. 

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.

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.
