1. Remove the factory connections between
Figure
2 J5 and J7 ports (see Figure 2 ), and the DC
output of Figure 1 .
2. Connect the external DC power supply
“Ground“ J7 “GND”. Keep the jumper connection between
J5 and J7 as both ports are powered from the same source.
3. Disconnect the fan connection from J1 if the external DC power supply is higher than 12VDC.
4. If available, make the
‘Earth Ground’ connection to ‘ST1 - Earth Ground’ terminal on
Figure 2 .
5. If the Data Pro has the front panel power button installed, carefully remove the power wire from the
bottom of the switch (see Figure 3
