The Video Server provides a very flexible general I/O interface to combine with the user's security
devices such as sensors, alarms, lighting or door locks. The general I/O terminal block has six pins for
device control. These pins can be divided into two categories based on their functions, including RS485
and digital inputs and outputs.
If the device connected to COM has an RS485 interface, wire two control lines to pin 5 and pin 6. After
switching to RS485 on the configuration page, the PTZ control commands will be directed through pin 5
and pin 6. If the distance from the controlled device is too far to allow accurate function, an external
power source may be used to pull high the RS485 signal.
The Video Server provides one digital input and one relay switch for device control. Pin 1 and pin 2 can
be connected to an external sensor and the state of voltage will be monitored according to the
programmed scripts in configuration. The relay switch can be used to turn on or off the external device.
