C2N-IIF Digital Output Signal Descriptions
INPUT DESCRIPTION
DoorBellBtn Goes high when door bell switch closes
(pushed) for as long as the signal remains high.
WAV_Playing Goes high when a WAV file is playing. Remains
high for as long as the WAV file is playing.
Input1_Press
through
Input18_Press
Goes high when a corresponding input is low. If
connected to a keypad, this means that the
corresponding button is being pressed.
In Essex mode, when a button on the Essex
keypad is pressed, the corresponding output will
briefly pulse. When discrete input 6 is low (i.e. a
button press), the corresponding output will
remain high for as long as the input is low.
In Discrete mode, when inputs 1 through 6 are
low, the corresponding output will remain high
for as long as the input is low.
In Matrix mode, inputs 1 through 4 are mapped
to 16 button presses (outputs 5 through 8 are
also mapped to the 16 button presses). When
buttons 1 through 16 on the keypad are
pressed, the corresponding output will remain
high for as long as the button is pressed. When
discrete inputs 5 or 6 are low, outputs 17 and 18
(respectively) will remain high for as long as the
input equals logic low.
