Power source
Pair of pin 14, 15 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 14 and pin 15
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.
result in serious damage.
RS485 interface
The PTZ control commands can be directed through pin 13 and pin 26 to control the PTZ
cameras. If the distance from the controlled device is too far to allow accurate function,
an external power source may be used to amplify the RS485 signal.

Digital I/O control
Video Server provides four pairs of digital inputs and four sets of relay switches. Pin 9 to
