i want to use my old xprotolab without usb. Now i dont know how to connect the power. The manual describes a 6x1 pin connector , i have a 3x2 connector.
Edit: can i just use the +5v of the ?back? pins (besides the logic ins)? (The -5 is an output??)

Yes, you can apply power thru +5V and GND. You can take a look at schematics to be sure.
