Power source

Pair of pin 11, 12 of AC or DC input is a replacement with the power adapter in case the

range cannot meet the requirement. The voltage of the power source can be AC or DC

and should fall in the range between 12V and 15V. Polarity does not matter. The DC

output through Pin 1, 2 is fed from power adapter of Video Server or pin 11 and pin 12

if an external power source is attached. The current of external devices is limited to less

than 500mA.

The power adapter of Video Server and the external power supply are prohibited to

exist together. Only one source can feed power to Video Server. Improper usage will

result in serious damage.

RS485 interface

If the device connected to COM1 has an RS485 interface, wire two control lines to pin 9

and pin 10. After switching to RS485 on the configuration page, the PTZ control

commands will be directed through pin 9 and pin 10. If the distance from the controlled
