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
