Table 11.
Systems that use the active high mode for Event output must be wired point-to-point
between the STTS2002 and the sensing controller. Wire-OR configurations should not be
used with active high Event output since any device pulling the Event output signal low will
mask the other devices on the bus. Also note that the normal state of Event output in active
high mode is a ‘0’ which will constantly draw power through the pull-up resistor.
