Use a cheap phone sync cable with the serial port


Contents []
Possible Cheaper Alternative to this Cable

You may want to look at the instructions for the use of a Nokia DKU-5 or CA-42 cable instead on the  page.

mindbender: i still have about 7 cables here...unfortunately my LS Pro`s slide-serial is somewhat not working anymore. so i do not know how to test the cables. i either need another box or i send it in parts.

Here some pictures from the build-process (mindbender had fun with it)

I opened all FutureDial Cables to check if all cables used the same color-coding + Profilic-Chip:



Prebuilt cables will use a heat-shrink-tube to make the cables more stable.


What do i need?

We organized some futuredial phone sync cables mentioned at  Section "USB-Connection". These phone sync cables are quite cheap at ebay. you can buy any other cable mentioned at that wikipage...the only difference will be the color coding of the cables. 
OR: buy some from here:  here is the pinout:

Quotation from :
Most of the cheap cables are based on a Prolific PL2303 chipset ( ) which is supported under Windows () and Linux. A third party Nokia data cable for a 8000 series phone has been used with no problems. A data cable from the Siemens C25/35/45 works too. The cables from the old models (i.e. C25) costs a 2..3$.
Quotation end

Comment: Find many more pinouts at 


What to check first

Open the dongle in the middle of the cable to check if the profilic chip is used. You need to check the color coding of the wires. Best would be to just leave the dongle open. In my example here we have the color coding for the FutureDial-Cables. If you have a different one check  for the color coding.

Open the phone connector of the cable


you can slide out all the cables ends out of the connector. Use flat nose pliers.


Prepare the phone sync cable



In this picture: Green is GND, Yellow is RX (as in "data entering the LSPro") and Orange is TX. The not connected terminal is VCC.
