range between 12V and 15V. Polarity does not matter if you use AC. The DC output through Pin 1 and Pin 2 is fed from the power adaptor of the Video Server or pin 11 and pin 12 if an external power source is attached. The current of external devices is limited to less than 500 mA.

b.COM 1 RS-485:If the device connected to the COM1 port has an RS-485 interface, such as a PTZ camera control, wire the RS-485 Data+ and Data- control lines to COM RS-485 pin “+” and pin “ –”. If the distance from the controlled device is too long to allow accurate function, an external power source may be used to pull the RS-485 signal to “high” status.

c.Digital Input/Relay Output: VPort 2140 Video Server provides 4 digital inputs and 2 relay outputs. 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 (Normal Open), “NC” (Normal Close) pin, and “C” pin (Common) can be used to turn an external alarm on or off. When the system starts up, both relay outputs’ “Common” pin will short the “NC” pin. A simple example is illustrated in the diagram below.

If DI1 is configured to “rising” status, so that DO1 is driven to “high” status (resulting in DO1’s “Common” pin shorting the “NO” pin), the light bulb will light up when DI1’s signal changes from 0V to 12V.

COM 1 RS-485 and COM 1 RS-232 share the same UART chip. If one of the ports is being used, the other port will not be available.

11: 10/100 Mbps Ethernet

An RJ45 10/100 Mbps Ethernet connector can be connected to an Ethernet network with a UTP category 5 cable of length shorter than 100 meters (according to the Ethernet standard). Once the Ethernet cable is connected correctly, the Video Server will use the Ethernet interface before using the modem attached to COM 2.

12: INPUT 12 VDC

Connect the power jack of the included 12 VDC power adaptor. Connecting the power adaptor should be the last step involved in the Video Server hardware installation. Administrators may feed an external power source through pins 11 and 12 of the GPIO terminal block to replace the power adapter.

The Video Server power adaptor and the external power supply (from pins 11 and 12 of the Terminal Block) cannot be used at the same time. Only one power source can be used to feed power to the Video Server. Improper usage will result in serious damage to your Video Server.
