VPort 251 User’s Manual System Configuration
NOTE
If users want to connect the PTZ control or keyboard with a PC to control the PTZ camera
connected with VPort, please refer to the VPort SDK PLUS- ActiveX SDK to get the Moxa
RealCOM driver and implementation information.
Setting Up a Preset Position
Administrators can use the Preset Position function to set up the behavior of the PTZ camera in
advance, and then users with camera control privilege can move the camera’s lens to a preset
position without the need to control the pan, tilt, and zoom buttons on the VPort 251’s homepage.
Set Up Custom Commands
VPort products provide 10 custom commands in addition to the general pan, tilt, zoom, and preset
functions, which are also shown on the PTZ Control Panel . Administrators can click on Setup
Custom Commands to configure the commands, and refer to the manual enclosed with the
attached PTZ camera to set up frequently-used functions. The Command should be entered in
ASCII format. The VPort will translate the commands into binary code and then send the data out
through the serial port. For instance, the text string 81 01ABCDEF will be translated into five
bytes of hexadecimal: 81, 01, AB, CD, and EF. The maximum length of a command string is 60,
which is equivalent to 30 hexadecimal bytes. The Display string is for the text on the command
buttons and should be less than 8 characters. If Custom Camera is selected, there will be more
commands for PTZF that relate to custom camera.
