Pin 1: GND ( external supply low voltage )

Pin 2: VCC ( external supply high voltage )

Pin 3: SYNC ( external trigger signal )

Pin4 (High Alarm) and pin5 (Low Alarm) signals must be

synchronized with pin3. Pin5 and pin4 will not function

(always low) unless SYNC (pin3) is high. If SYNC is low, then

pin4 and pin5 will be low.

Pin4

: High Alarm

If the reading is higher than the high alarm setpoint, then (pin 4)

will be high, otherwise, it will be low.

Pin 5

: Low Alarm

If the reading is less than or equal to the low alarm limit, (pin 5)

will go high.

The Pin 4 and 5 outputs may be delayed 0.4 seconds due to the

datalogger’s A/D scanning time.
