Pin layout GPS to XDA cable needed

[FVH]

L.S.

Can some body help me to the pinlayout for a cable that connects a Haicon GPS203e to a XDA.

I have the layout for the GPS and XDA connector and can figure out the RX TX GND and V+ myself.

What i am looking for is special connections for DCD, CTS, RTS and DTR. Do I need to connect them to e.g. eachother or gound to activate transmission??

I do not know about the Haicom but you should not need to connect these.
Most GPS transmit constant NMEA signal while it is turned on (power on and with satellite lock). The biggest problem for you is how to power the GPS.

Thanks for your reply,

Power should not be an issue, i will connect to the XDA carkit which has a regulated supply for the XDA that should work for the GPS.

What I have seen in the past is that some of the additional RS-232 control lines have to be connected either to each other or ground to activate communication. I am wondering if somebody has a layout of the XDA cable for Haicom (three-way cable : lighterplug/gps/xda)

You do NOT need to connect or short any of the other lines to make this work. I've done the same with a Pharos GPS and custom car kit, and only connected the data and ground lines.

Today I tried to hook up the GPS to the XDA carkit as suggested (only GND TX and RX) but Tom Tom will generate an error saying it cannot connect to com1:

I noticed a difference in behaviour when using the orginal cable: when connecting the XDA it opens active sync immediatly.

Did some reverse engineering and found you need to connect the DCD to +5 volts. After that it works as designed.

Got the XDA carkit running with a Haicon GPS!

Do you have connected Heicon GPS to XDA ? If so, can you post me the pinout connection to use Heicon with XDA ? Many thanks in advance.
P.S. Sorry, i don't want to make disasters.
Thanks again

ConteMax I have received your message to my e-mail adres last week and have sent you a reply to your questions. If you need the layout, please have a look at the following website: http://www.vanhemert.biz/Car_Kit_GPS_Connection.htm This page describes how to connect a Haicon 203e GPS mouse to the O2 carkit.

If you do not have a carkit, have a look at the connector page at : http://www.xda-developers.com/connectors/ it describes the layout of the XDA connector.

The only thing you have to do is connect the GND, RX, TX, VCC and DCD line to get the thing up and running.

(info@carkit24.de) and i send you a Fax with original colors of cables.
You can use all GPS-Mouse with PS2 and serial-Connector.

Can some body help me to the pinlayout for a cable that connects a GPS ( rs232 ) receiver to a XDA.

I have the layout for the GPS and XDA

We need to powered GPS and XDA ( GND and +5V ) and after :

GPS TX must be connected on pin 10 ( RX RS232 ) XDA connector
GPS RX must be connected on pin 8 ( RX RS232 ) XDA connector

Is it right ?

I would be interested to know if the new XDA IIs has the same pinout as the earlier XDA's.

It's all in the cause fo getting the XDA IIs to accept a serial connection from my garmin GPS V.

Currently i get an error indicating COM 1 is unavailable

Any other suggestions welcome

Guest, check under setting/connections, make sure that beams is unchecked, this will release com 1, also if you have an external keyboard driver loaded you will need to deactivate this also.
