Single Door Controller (SDC) Configuration
The administrator can configure the Single Door Controller (SDC) parameters in order to control
the access through a door when specific actions are triggered on MorphoAccess® SIGMA Family
terminal. For example, on successful identification of a user, door must open automatically to
allow the user into the premises.
SDC Configuration allows an administrator to set either of the two states as below:
GPIO General Mode:
General Purpose Input Output (GPIO) mode is used for passing multiple signals to the door panel
when an action is triggered on the terminal. By default, GPIO Mode is enabled.
GPI: General Purpose Input (GPI) has three TTL lines available, i.e., Line 0, 1 and 2. The
administrator can configure a GPI line to trigger an action on the terminal from a distant
system, when set as active (low and/or high). The administrator can activate multiple
lines for same action or multiple actions. The signal is sent when following actions are
triggered on terminal:
Delete Templates: On selection of this action, terminal will erase all the biometric
templates of specified template ID i.e. if more than one template are available with
different index then all those templates will be removed. The signal is sent when
following actions are triggered on terminal.
Reboot Terminal: This action will reboot terminal
Alarm: Terminal will buzzer the alarm for 5 seconds. This alarm can be stop from Tamper
screen with Reset, even though it is not really a Tamper Alarm.
GPO: General Purpose Output has three TTL line available, i.e. Line 0, 1 and 2. Terminal
can send Signals simultaneously through multiple configured GPO lines to the door
panel. The signal is sent when following actions are triggered on terminal:
Verify/Identify Passed: After a successful verification
Verify/Identify Failed: After verification failed
Finger not Detected: When finger is not detected as per requirement
Full Administrator User: When administrator with full administrative rights tries to login,
an action is triggered on GPO line
Biometric Administrator User: When administrator with database (biometric)
administrative rights tries to login, an action is triggered on GPO line
Device Boot up: When a terminal is booted up, either from a power cycle or from a soft
reboot.
