need help from bosch kts 520 users please

[paro44]

I got a kts 520 main unit where the usb port is ripped off. It was already repaired once (not by me) and broke again. Some solder pads and copper lines are ripped off, too. So i need some information to make it working again.
The red led on pcb is on, the green led outside is flashing sometimes (shortly).

I tried to connect it with db-9 serial cable an 15v power supply. As i have no genuine cable i found a wiring diagramm and made one myself. Can someone confirm if the serial connecting cable has this wiring or is there something missing/wrong?
(db9female --- db9 female)
2 --- 3
3 --- 2
4 --- 4
5 --- 5
shield/case --- shield/case

I got a communication error between esi and kts with that cable, couldn't update the firmware.


Can someone tell me where to connect the 4 usb-wires? There is a pdiusbd12 on it, i found pinning diagram, but i'm unsure where to connect vcc, ground, data+ and data- on pcb. Pinning diagram says:
5 --- ground
24 --- vcc
25 --- data-
26 --- data+
Can someone tell me where the wires from the usb port are soldered originally?

Any help is welcome. A working serial connection would be ok, usb would be better of course.

Sorry to bump again...

Is there really nobody, who has the serial connection cable for kts and who can tell me the correct pinout? Are there lines missing/wrong in my first post?


With usb i had no luck until now. I soldered the usb wires (where i thought it's correct) but the connected laptop only said, that the usb device need to much electric power.

There are some capacitor onboard, one was replaced with electrolytic capacitor, might that be the problem?
