Jupiter GPS-Empfänger TU30-D140 / TU30-D145 
Navman / Rockwell / Conexant Jupiter TU30-D145-039 OEM CR-Modul (GPS - Receiver ) 

Achtung: Nur die Version 039 hat einen Antennen-Stecker wie Bild gut zu erkennen ist ;o)

Der GPS - Empfänger besitzt eine 20 pol. Steckleiste mit allen Ausgangssignalen, 
wie z.B. den NMEA-Protokoll-Ausgang. 

Das GPS-Modul ist unbenutzt / neuwertig und betriebsbereit. 

Besonders ist das GPS-Modul geeignet zum Bau von GPS - Frequenznormalen, 
da das GPS-Modul bis zu GPS-Satelliten empfängt und ein zeitsynchrones 1 PPS 
und 10 KHz-Signal höchster Genauigkeit von 10exp-12 liefert.  

Ein ausführliches Datenblatt mit der Pinbelegung ist 
hier > http://aprs.gids.nl/gpskit/documents/rockwell/jupiter-gps-board.pdf zu finden.
Prüfkabel befinden sich leider nicht im Lieferumfang. 

Ideal für Bastler oder Personen die sich günstig einen GPS Tracking System bauen wollen.

Introduction

The Rockwell Jupiter TU30-D140 / TU30-D145 - 039 is a OEM only for CR Designed-GPS receiver module that 
is designed to be implemented as part of a larger design, like a vehicle tracking system, navigational system, 
time/clock reference etc. (by lungo)

This is a   all-in-view receiver. The module is 4 by 7 cm, and has a 20 pins connector for the various signals 
and power supply's and a MCX connector to for the GPS antenna. (by lungo)
20 pin interface connector

This 20-pin header has all the power supply, input and output signals exept the GPS antennasignal. 
The header has a 2.0 mm pitch, which is not very common. It is possible to create an adapter using a 2.5"-to-3.5" convertor 
PCB meant to connect laptop harddiscs to normal pc's. These can be bought in PC shops for around 10 euro. 
This adapter needs some work before you can use it. Some points are connected together on ground, and some points are not connected at all. 
With a sharp knife and some short pieces of wire you can cut away the unwanted ground connections and make a 1-to-1 adapter. 2mm pitch 
connectors are also used for internal wiring in mouse units and floppy disc drives. Another possibility is to remove the contacts from a ic-socket, 
the type with tooled bus-contacts (Augat), and use these to connect wires. Or you can directly solder wires to the pins or make a special PCB. 
20p connector signal description
pin 1 (square solder island) (by lungo) 
Power supply for the active antenna. This voltage is put on the center conductor of the antenna connector. 
Do NOT USE it with a passive antenna!! Maximum of 12V @ 100mA. Most of the active antenna's work at 5V or even 3.3V 
for the newest types and consume between 15 and 50 mA. (by lungo) 
pin 2Supply for the receiver itself. Should be 5V +/- 0,25V. The receiver consumes about 200mA. When in MR-active mode (see below) 
around 100mA. The absolute minimum for the receiver to operate is 4.5V. (by lungo) 
pin 3Battery backup power input. This 3 to 5V input feeds the static ram and real-time clock chips of the module when there is no power 
supplied on pin 2. Current consumption is then (and only then) between 40uA(3V) to 80uA(5V). This voltage is needed to keep the 
real-time clock running and static ram contents valid. This is again needed to keep te re-aquisition time as short as possible. 
You can use a small NICD or NIMH cell with a charging circuit, or a goldcap. A lithium cell can be used, but only if the receiver would 
be in operation most of the time, since the current consumption would drain a Li cell in a few weeks. (by lungo) 
pin 4Slot hole - no pin - Not in use (by lungo) 
pin 5Master Reset. The receiver is reset if this line is pulled to ground. As long as the line is 'low' the receiver is in a low-power mode. 
However, low-power mode in this case still means a 100mA current consumption. (by lungo) 
pin 6, 9 and 14reserved - do not connect anything or ask me for more information (by lungo) 
pin 7 & 8These are digital inputs that define the startup mode of the receiver. These must either be connected 
to ground level, of pulled-up with a 10k resistor to +5V (by lungo) 
7: NMEA protocol select.
When this line is low (ground) the receiver will always start in NMEA-0183 mode: ascii messages 
in 4800bd, no parity, 8 databits and 1 stopbit.
If this line is pulled high the start mode is determined by the state of pin 8. (by lungo) 
8: ROM default select.
If this line is pulled to ground the receiver will always start with the factory default values from the preprogrammed ROM memory.
When this line is high the initial values are taken from static ram (if a battery was connected to pin 2) or from eeprom. 
These initial values include the last known position and date/time, satellite orbital data, communication parameters etc. (by lungo)

For most of the applications you will want pin 7 to be low and pin 8 to be high. The receiver will than always start in 
NMEA0183 mode and uses the data in sram / eeprom for the initial calculations. 
See for more details the datasheet jupiter-gps-board.pdf @ (by lungo) 
pin 10,13,16,17 and 18Ground. These pins should all be connected to ground. (by lungo) 
pin 11 and 12Serial output (11) and input (12). This is the main serial port over which the application (pc, laptop, aprs etc) communicates. 
These lines work on TTL levels. To be able to talk with a PC you need a ttl<>rs232 converter like a MAX232 or a LT1281. 
Although the rs232 levels officially are +3..+12V for a "0" or "on" and -3..-12V for a "1" or "off", most of the pc's and laptops also work fine with 5V and 0V. 
If you want to try this, all you need is a 74HCT04 cmos inverter and some passive components. (by lungo) 
pin 15Serial input, also on TTL level. This port is meant for RTCM104 differential gps correction messages. *
No special configuration is neccesary - if valid dgps data is supplied the receiver will adjust its calculations accordingly.(by lungo) 
pin 19 1 PPS (puls per second) signal. This is a TTL signal with a frequency of exactly 1 Hz. 
The pulse length is exactly 25.6 ms and the rising edge is within 1us from the UTC second transition. 
There is software available that synchronizes the time in your PC and that expects a 1pps signal on the DCD line, 
so if you make an interface yourself you could use this. (by lungo) 
pin 2010 kHz TTL signal. This signal is also synchronous with pin 19 and has a long-term accurate to 1uHz (microhertz) 
or better, if the receiver has a "fix" on the GPS satellites. (by lungo)
