Wiring Recommendations
IDEMIA recommends using a gauge AWG20 for 12VDC power supply (when the
terminal is not powered using POE feature).
The voltage must be measured on the product block connector and must be equal to
12VDC-24VDC (-15% / +10%)
For information, this table shows the maximum drop voltage observed on the terminal
MorphoAccess® VP MD, depending on the length of the cable:
