COM port
This RS232 serial port can connect with a modem or included null modem cable to utilize
dial-up network when Ethernet is not available. If Video Server operates with Ethernet
interface, administrators may use this port to control PTZ camera attached to VIDEO.

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.
Video Server provides one digital input and one relay switch. Pin 1 and pin 2 can be
connected to 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
external devices.
