Overview The VPort 451 is a 1-channel industrial video encoder with MPEG4 and MJPEG video compression algorithm that provides a maximum of three video streams (two MPEG4, one MJPEG) simultaneously. The video streams can be used for different purposes, such as viewing, recording, and analyzing. The low latency (<200 milliseconds) of the VPort 451 makes it an optimal solution for mission-critical video applications, which require real-time video display.

Step 4: Connecting motorized PTZ cameras and serial devices The VPort 451 has two RS-232/422/485 ports. One is a COM PORT with DB9 male connector, and the other is a PTZ PORT with 5-pin terminal block connector. Both ports can be used for connecting PTZ control cables for controlling PTZ cameras over the TCP/IP network.

Wiring Requirements WARNING Safety First! Be sure to disconnect the power cord before installing and/or wiring your Moxa VPort 451. Calculate the maximum possible current in each power wire and common wire. Observe all electrical codes dictating the maximum allowable current for each wire size. If the current goes above the maximum ratings, the wiring could overheat, causing serious damage to your equipment.
Wiring the Redundant Power Inputs The VPort 451 has two sets of power input, power input 1 and power input 2, which are located on the 6-pin and 8-pin terminal block connectors. Top and front views of the terminal block connectors are shown here. - 15 -...
ATTENTION The current and power capacity of the relay output is a maximum of 24 VDC @ 1A. You should be careful not to exceed this power specification. Wiring the Digital Inputs The VPort 451 has four sets of digital input, DI1, DI2, DI3 and DI4.
10/100BaseT(X) Ethernet Port Connection The 10/100BaseT(X) port located on the VPort 451’s front panel is used to connect to Ethernet-enabled devices. Pinouts for both MDI (NIC-type) ports and MDI-X (HUB/Switch-type) ports are illustrated below, along with cable wiring diagrams for straight-through and cross-over Ethernet cables.

SC-Port Pinouts SC-port to SC-port Cable Wiring Cable Wiring COM Port A COM PORT is located on the front panel for connecting a PTZ motorized camera or serial device. The COM port transmits RS-232 or RS-422/485 signals over the TCP/IP network. Users can use this COM port (DB9 male connector) to monitor data or control a serial device, or for the control of a PTZ motorized camera.
PTZ port A PTZ port is located on the VPort 451’s front panel. The port is used to connect a PTZ motorized camera or device so that the camera or device can be controlled from the VPort over the IP network. The PTZ port supports RS-232 or RS-422/485 signals through a terminal block.
NOTE Follow these steps to remove the SD card: Step1: Open the upper case. Step2: Wait a few seconds to allow the SD card to complete existing file storing activity. Step3: If the SD LED indicator is lighted in green, it means the unmounting of the SD card was successful, and you can take out the SD card.
No serial data is transmitting. SD card is mounted correctly and is ready to use. GREEN Error in mounting SD card. Flash No SD card in the slot. Hardware Reset A recessed RESET button is provided for restoring the system to the factory default settings.
