Description
This article will describe how to use the DI/DO feature of VS13X-P.
Requirement
● Milesight VS133-P/VS135-P: firmware version v133.1.0.7-r2/v135.1.0.7 and later
● Multi-interface Cable
● Kindly note that Tailgating Detection, Digital output trigger, and Input Enable Line Crossing Count External functions cannot be enabled at the same time.
Digital Input Section
Wiring Example
For the multi-interface, points A and B are not connected. The IN point needs to be connected to an external signal input device, and the G point should be grounded. Ensure that the DI input voltage is between 2 and 5V.
Configuration
Input Enable Line Crossing Count Externally.
You can enable this function in the Rule> I/O Settings module.
This function is disabled by default. When enabled, it will simultaneously check the current status of the DI interface to see if it meets the trigger condition when a person passes by. Counting will only occur if the condition is met; otherwise, it will not count.
Configuration instructions are as follows
Current status: Indicates the status of the DI interface
Trigger state: Optional high or low level
High Status: When the DI is in high power normal state, the number is counted only after the personnel pass
Low Status: When the current DI status is low power level, the number is counted only after the personnel pass
Digital Output Section
Wiring Example
When Tailgating Detection or Trigger Digital Output function is enabled, use the following figure to connect cables.
For multiple interfaces, connect only points A and B. Make sure the power supply is less than 60V, 1A.
Configuration
1.Tailgating Detection.
You can enable this function in the Rule> I/O Settings>Tailgating Detection.
When the device is used in areas requiring card swiping for entry and exit, this feature can be enabled to determine if anyone is tailgating through the turnstile. Upon detecting an abnormal event, an alarm is triggered. The device supports DO signal output and reporting alarm data via MQTT/HTTP. There are two alarm methods: one is DO alarm signal output, and the other is reporting alarm data via MQTT or HTTP.
Configuration instructions are as follows：
Input Current Status:Current signal level status and supports manual updates.
Input Trigger Status:Configure whether the external input trigger state is high level or low level.
Single Trigger Validity Period:Set the effective time for a single external input trigger, range: 160 seconds.
Select Counting Detection Line: Correlate the corresponding detection line, currently this function is only applicable to detect one gate (detect one line)
Digital Output Pulse Width: Configure the pulse width of the alarm.The range is 100-1000ms
By default, high level is selected.
When high level is selected, each time the external input changes from low level to high level, the system will increment the effective trigger count by 1 and start calculating the effective time of this trigger.
When low level is selected, each time the external input changes from high level to low level, the system will increment the effective trigger count by 1 and start calculating the effective time of this trigger.
The following is an example process:
2. Trigger Digital Output
You can enable this function in the Rule> I/O Settings>Trigger Digital Output.
When the trigger event is enabled, a pulse signal with the pulse width corresponding to the trigger event is sent to trigger the external output.
Synchronized Pulse Interval: When multiple people pass through or multiple events are triggered simultaneously, the time interval between the transmission of multiple pulse signals.
