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 two sets of relay switches. Pin 13 to
pin 20 can be connected to external sensors and the state of voltage will be monitored
according to the programmed conditions on the configuration page or the external script
file. Both relay switches can be used to turn on or off external devices. When the system
starts up, COMMON of both relay switches will be short with NC. A simple diagram of
example is shown below.
Power adapter
Plug the power jack of the included power adapter to Video Server. Connecting the power
adapter should be the last operation while physically installing Video Server.
Administrators may feed an external power source through pin 11 and pin 12 of the
general I/O terminal block to replace the power adapter.
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.
If DI1 in configuration is set as rising to
drive DO1 to high that denotes COMMON of
DO1 short with NO, then the bulb will light
when DI1 signal changes from 0V to 12V.
