VPort D361
Introduction
1-7
RS-232/RS-422/RS-485 PTZ COM Port
The VPort D361 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 to transmit the PTZ control signal through a TCP/IP network to the VPort D361 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.
12/24 VDC and 24 VAC Power Inputs
The VPort D361’s power input supports both 12/24 VDC and 24 VAC power for greater versatility.
NOTE
The supported power input specifications for the VPort D361 series are 12 to 32 VDC for a 12/24 VDC power
input, or 18 to 30 VAC for a 24 VAC power input. This differs from the Moxa EDS switch’s 12 to 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 D361’s top panel. The terminal
blocks provide 2 digital inputs (DIs), 2 relay outputs (DOs), and 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 D361 to create an intelligent alarm system for system operation (power failure, disconnected network).
In addition, the VPort D361’s DI 1 and DI 2 can also be used for controlling the selection of the video source.
The Administrator can set up this function by checking the Enable DI Change checkbox under System
Configuration
Video Source
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).
