Introduction

Rear Panel

8: COM1 & COM 2

There are 2 COM ports on VPort 2140’s rear panel.

a.COM 1 (RS-232): This RS-232 serial port can connect with an RS-232 PTZ camera. For RS-485 PTZ cameras, the administrator can use the General I/O terminal block’s COM 1 (RS-485) .

b.COM 2 (RS-232): This RS-232 serial port can connect to a modem, or you can use the included null modem cable to utilize a dial-up network when Ethernet is not available. If the Video Server is connected to the network via the Ethernet interface, you can also use this RS-232 serial port to control an RS-232 PTZ camera.

9 & 10: General I/O terminal block

VPort 2140 provides a very flexible general I/O interface that can be used with security devices, such as sensors, alarms, lighting fixtures, or door locks. Two green connectors are included in the package to connect external devices. The general I/O terminal block has 20 pins for device control. These pins can be divided into three categories based on their functions, including power source, RS-485 and digital inputs and outputs.
