Line 2 Wiring - HikRobot CameraLink Area Scan Camera User Manual

If the VCC of NPN device is 24 VDC, and it is recommended to use 1 KΩ to 4.7 KΩ pull-up resistor.
If the VCC of NPN device is 12 VDC, and it is recommended to use 1 KΩ pull-up resistor.

7.2.3 Line 2 Wiring

As bi-direction I/O Circuit, Line 2 can be used as both input signal and output signal.
Type IV camera and type V camera do not have bi-direction I/O function.
Line 2 Configured as Input
When the camera uses Line 2 as hardware trigger source, wirings are different with different
external devices of input signal.
 PNP Device
It is recommended to use 330 Ω pull-down resistor.
 NPN Device
If the VCC of NPN device is 24 VDC, and it is recommended to use 1 KΩ to 4.7 KΩ pull-up resistor.
If the VCC of NPN device is 12 VDC, and it is recommended to use 1 KΩ pull-up resistor.
