GPS for the XDA carkit from O2

[istaveren]

I received the XDA carkit. PDF can be found here http://stefan-bauer.net/xda_carkit.pdf.

Now I would like to connect a GPS device to it. But does anyone know what kind of connector it is on the serial cable of the carkit?

Or what the meaning of the colors on the connector is?

Braun, black, orange, green, yellow, blue, red and purple?

The amount of wires is correct for

5 GND
6 RS232_DCD
7 RS232_CTS
8 RS232_TXD
9 RS232_RTS
10 RS232_RXD
11 RS232_DTR
20 V_ADP

But what are there matching colors?

A picture of the connector http://iwex.dyndns.org:8080/temp/xda/connector2.jpg. More pictures can be found here (http://iwex.dyndns.org:8080/temp/xda/) . I heard a rumor that it could be a 'short form connector type JS 6503' but I don’t know how to check this:?:.

Hi,

I have connected a GPS reciever to the xda. Look at www.farrella.com under 'notes on kit' for wiring.

A simple way of determining the connector wiring is with a multimeter (if the probes are too thick, use a wire with a very small diameter to start testing which colours go to which pin. All the details of the connector are detailed on this site.

I looked at the picture and its not very clear what wires comes out of the cradle. Any chance you could do a better picture and post it??

Hey.

Got a question about the Carkit.
Have you already tested it? Can you see how it´s solved to mute the Radio if a ring comes?
Have you already some experieneces with the Car Kit?

Spent an hour on the phone with germany, nobody wants to give me the details for the GPS connector on the XDA Carkit. They are all waiting for Cebit and the big O2 GPS announcement!.

Decided to figure it out my self. I have mailed the results to the webmaster of this site and asked him to publish it on the connector page.

Remember, no warranties or support, just best effort!

Andrew,

That carkit looks a lot like the one I could get my hands on but it's a slightly different type (HFJ-3).

It has 5 connectors:
A) 8 pin Rj-45 with label HANDSET/ACCESSORY
B) 10 pin RJ-45 like with label HOLDER/BOOSTER
C) speaker
D) mic
E) Power
Red (12 Volt)
Yellow (CRM) < must be car radio muting
Black (ground)
Blue (ignition sense)

So I have figured out what C, D and E are. Pretty easy.
But do you have any idea what the eight pins of A) are. I suppose it is pretty much the same as yours but I could not find those details in your schematics.

And has anyone any idea on what connector B) does?

The schema is not published yet, so here´s the layout of the connector:

Purple RTS
Red DCD
Blue DTR
Yellow CTS
Green RXD
Orange TXD
Black GND
Brown +5,47V swiched on with ignition, switched of 1 hour after ignition switch off.

Good luck,

Francois

Here are the pin outs of the HFU-2 Kit (maybe also HFU-3)

15 Pin Connector (Pin 1 nearest SPK)

1 NC
2 XMIC
3 SGND
4 XEAR
5+6 L_GND
7 CHG_CTRL
8+9 V_IN
10 MBUS
11 L_GND
12 VB
13 FBUS_RX
14 FBUS_TX
15 NC

10 Pin connector (pin 1 is nearest power input connector)

1 NC
2 +10V
3 FBUS_RX
4 MBUS
5 HSHOOK
6 FBUS_TX
7 GND
8 HS_MIC
9 HS_EAR

I'd say that using pins 5/7/8/9 that the XDA MIGHT be able to be connected to this connector (usually not used as its for a data/head-set). Pin 5 could hold the key OR by using a schmitt trigger & 555 timer to hold for say 3 secs

I found an site that calculates the resistor values for a schmitt trigger:
http://hyperphysics.phy-astr.gsu.edu/hbase/electronic/schmitt.html

and for a 555 timer:
http://www.uoguelph.ca/~antoon/gadgets/555/555.html

So a Radio mute can be achived by combining these circuits together.

Sorry Climber ,
I only glanced at your posting about the HFJ-3 before posting my post. It must be a very old one for possibly a Nokia BRICK phone, as it gives an output for a booster.

Andrew,

Thanks, I'll start working on this right away. I'll post anything I discover but it will take some time since I have not received my XDA yet :cry:

Regards Robert

[climber]

well....

I have a hfu-2 in my current car but it is company provided so I should be a 'little bit' careful with it. The other one is indeed the BRICK version 2110 phone YUCK of 'some' time ago.

The phone still works and I use it for the 'lets see if this will fit here' experiments. I don't want to destroy any PDA or my company phone

These pin-outs are not for the 'BRICK' car kit. It is for the HFU-2 only.

Sorry for any confusion.

Andrew
