Input Connections (With I/O Option Only)
Input connections are located on the back of the DRO. These connections allow signals
from external devices to activate specific DRO functions.
DRO functions are activated by applying a +24 VDC, 10 mA signal for a minimum of
100 ms. Inputs to the DRO are optically coupled for protection. The Ground pin is the
reference ground for the inputs and should always be used.
