5 Reset to Factory Defaults
It is possible to reset the PD-1160 to factory default settings without establishing a communication link.
This might be helpful in case communication parameters of the preferred interface have been set to
unknown values or got accidentally lost.
For this procedure two pads on the bottom side of the board have to be shortened (see Figure 5.1).
Short these two pads.
Figure 5.1 Reset to factory default settings
PERFORM THE FOLLOWING STEPS:
1. Power supply off and USB cable disconnected
2. Short two pads as marked in Figure 5.1
3. Power up board (power via USB is sufficient for this
purpose)
4. Wait until the on-board red and green LEDs start
flashing fast (this might take a while)
5. Power-off board (disconnect USB cable)
6. Remove short between pads
7. After switching on power-supply / connecting USB
cable all permanent settings have been restored to
factory defaults
