VPort D351 User’s Manual Introduction
10/100 Mbps Ethernet port
The VPort D351 provides one RJ45 Ethernet port for a 10/100 Mbps Ethernet connection. Two
LED indicators are located on the corner of the RJ45 Ethernet port to indicate if the link speed is
10 Mbps or 100 Mbps.
RS-232/RS-422/RS-485 PTZ COM port
The VPort D351 provides 1 RS-232/422/485 COM port for PTZ control. The port uses a 5-pin
terminal block connector with the following pin assignments.

NOTE
The VPort series video encoders support “Transparent PTZ Control,” which is listed in the
camera driver list. This function is used is to transmit the PTZ control signal through a TCP/IP
network to the VPort D351 video decoder or PC (additional Real COM driver required), and the
PTZ control panel or keyboard can directly control the PTZ camera or device. In this way, there is
no need for PTZ camera driver, and there are no protocol limitations for using a PTZ camera with
a VPort encoder.
Redundant 12/24 VDC and 24 VAC power inputs
The VPort D351 has two power inputs for redundancy. Each power input supports both 12/24
VDC and 24 VAC power for greater versatility.
NOTE
The supported power input specifications for the VPort D351 series are 12-32 VDC for a 12/24
VDC power input, or 18-30 VAC for a 24 VAC power input. This differs from the Moxa EDS
switch’s 12-45 VDC power input.
General I/O terminal blocks
One 6-pin terminal block and one 8-pin terminal block are located on the VPort D351’s top panel.
The terminal blocks provide 2 digital inputs (DI), 2 relay outputs (Relay), and the 2 power inputs.
These digital inputs and relay outputs are for linking to peripheral devices, such as sensors and
alarms, and can be employed when using the VPort D351 to create an intelligent alarm system for
system operation (power failure, disconnected network).
In addition, the VPort D351’s DI 1 and DI 2 can also be used for controlling the selection of the
video source. Administrators can set up this function by checking the Enable DI Change
checkbox under System Configuration Æ Video Source Æ Video Source List. DI 1 can then do
backward video source selection (e.g., from video source 2 to video source 1), and DI 2 can do
forward video source selection (e.g., from video source 1 to video source 2).
