7.1 Assembly Instructions ETXexpress® miniBaseboard
Follow the assembly instruction below to enable Single Supply operation:
For correct CPLD supply:
» Remove R710 (10kOhm; bottom)
» Mount R705 (100kOhm; bottom)
» Mount R61 (210kOhm; bottom)
To switch CPLD in single supply mode:
» Remove R712 (0R; bottom)
» Mount R711 (1kOhm, bottom)
To enable 5V Standby:
» Mount R46 (0R; top)
» Mount R60 (210kOhm; bottom)
To ensure that there is no short with the onboard generated voltages:
» Remove J58 (top), to ensure, that there is no short with the onboard generated voltages possible.
Optional:
» Remove R490 (0R, top) and mount on R491 (top) to enable the power save mode
» FAN1 output is 8.5V -12V. Place R51 (0R; bottom) to fix FAN1 output voltage to 5V
» FAN2 is not supported. Remove R53 (0R; bottom) and place it on R52 (bottom) to enable FAN2 with +5V
output voltage.
