Pinout 3210 (without guarantee)

If you remove the cover over the battery you can see six pins on the right hand side of the battery. There you can connect a datacable.

3210 from the back      
-1-  ?
-2- FBUS_TX
-3- GND
-4- MBUS
-5- FBUS_RX
-6- VPP ?

If you already have a datacable for 61xx (Fbus) - e.g. the one supplied with datasuite - you have to make these changes (for 61xx pinout look at 61xx-section):

61xx to 3210:
9 to 3
8 to 2
7 to 5

Here you can find a scheme for a Fbus datacable with 61xx pinout, so remember to make the changes mentioned before.
