Pin Number:
- External VCC: This pin outputs unregulated 12V DC when power on with 12V DC 1A adapter, it may be used to drive an external relay or sensor. For rack mount applications, it may used an external regulated 10-24V DC connection as system power. In which case the AC adapter must not be connected.
Caution: The electric current must not exceed 200mA when the external VCC outputs to drive external devices. Furthermore, overloading will cause damage to the AC adapter or internal components. If using external DC to input to system as power supply, it must conform to the specifications of regulated DC 10~24V, >10W; otherwise, it will damage the system or cause malfunctions.
- 485A
- 485B V for connecting with external PTZ devices, please contact your dealer/distributor to get information about supported PTZ models.
- GPIN1
- Relay_COM - Relay Common point.
- Relay_NO - Relay Normal Open point. It will set to on (Short with Relay_COM) when GPIO output is high.
- GND
