High-side/Low-side Switches at Digital
Outputs
At delivery the digital outputs are configured as high-side switches
and the frequency/PWM outputs as low-side switches. You can
change the output behavior of four digital and two frequency/PWM
outputs independently. This is done with jumpers which are marked
with the mnemonics of the outputs.

The high-side switches require a
separate voltage supply
via pin 1
and/or pin 2 on connector J1 (see also 3.1
Assignment/Applicable MicroMod Services on page 12). This
voltage supply is also needed for the low-side operation of the
