You can control the slope of the pulse from the alarm outputs
(the selected configuration is used for all four outputs). In the falling
edge mode, 0V (TTL low) indicates an alarm. In the rising edge mode,
+5V (TTL high) indicates an alarm. A Factory Reset (
*RST
command)
will reset the slope to falling edge.
Note :
Changing the slope of the output lines may cause the lines to
change state.
