IO Configuration
The face recognition terminal connects to gate machines, door locks, or access control buttons and sends the door
opening signal to them. Perform the following operations to complete configuration:
(1)
Choose
Setup
>
Common
>
Ports & Devices
and click the
IO Configuration
tab.
NOTE!
Some devices support the output from only one or zero IO ports and the IO port configuration
interface is different for the devices.
Some devices does not support door locks or access control buttons and the IO port
configuration interface is different for the devices.

Parameter Description
Parameter
Description
F1/F2/F3
F1/F2/F3 indicates the IO port of the face recognition terminal. Select the check box in the front.
Then, the configuration of the IO port will take effect.
IO ports support the following types of external devices:
Door lock: The face recognition terminal outputs door opening signals to door locks through
an IO port.
Pulse Width
here refers to one door opening duration. When the door opening duration
exceeds this time, the door magnet will generate an alarm.
Value range: [1–300]s; Default value: 5s
Door button: The face recognition terminal can receive the door opening signal from the
access control button through an IO port and sends the door opening signal to the door lock.
The pulse width value here indicates that a valid door opening signal is generated only when
the duration in which the door opening button is held down reaches the value here.
Value range: [0–20000]ms; Default value: 100ms
Alarm output: The face recognition terminal outputs alarms through an IO port.
Value range: [0–20000]ms; Default value: 100ms
Level Value
can be set to
Low Level
or
High Level
. The value should be consistent with the input
and output signal level supported by external devices.
Unlock Interval
It indicates the interval between two unlock operations. After the door is unlocked, it will not be
re-unlocked within the unlock interval even if a new unlock signal is received. In addition, the door
opening duration of the door lock will not be re-timed. If it is set to
0
, door unlock will be triggered
