The Video Server provides a very flexible general I/O interface that can be used with security devices, such as sensors, alarms, lighting fixtures, 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 the interface being used (RS-485 or DI/DO).

RS-485 COM

If the device (such as a PTZ camera control) connected to COM has an RS-485 interface, wire the RS-485 Data+ and Data- control lines to COM RS-485’s “+” pin and “ –” pin.

ATTENTION

Since RS-485 COM and RS-232 COM share the same UART chip, either RS-485 or RS-232 (but not both) can be used.

Digital Input/Relay Output

VPort 2310 Video Server provides one digital input and one relay output. The Digital Input’s “+” pin and “-” pin can be connected to an external sensor to monitor the voltage according to the programmed scripts in configuration (see the “Command Script for DI/DO & Camera’s Actions Setting” in Chapter 5). The Relay Output’s “NO” pin and “C” pin can be used to turn an external alarm on or off.
