VPort 2140 User’s Manual System Configuration
4-12
Purpose
The COM port connection has 3 purposes:
1. If the attached device is a PTZ camera, administrators must select the correct PTZ model
under PTZ driver options, since each PTZ camera has its own protocols for the PTZ functions.
Refer to Appendix B, Settings for Supported PTZ Cameras, to find out the PTZ cameras
that MOXA VPort 2140 Video Server supports. If the attached PTZ camera is not supported
by the VPort, administrators can select Custom Camera to enter the proprietary commands for
pan, tilt, zoom, and focus control.
2. If the attached device is not a PTZ camera, but another serial device, such as a video
multiplexer, etc., administrators can select the Generic CGI command to control the device
via CGI commands. For external device control, refer to Chapter 5, Advanced Applications,
under the URL Commands for DI/DO and Camera’s Actions settings section for more
details.
3. The default setting is None, which means that no other device is connected to the COM port.
Port Settings
After selecting the correct PTZ driver or Generic CGI command option, the next thing
administrators must do is configure Port settings, including Baud rate, Data bits, Stop bits, and
Parity bit. If the attached device is a PTZ camera, refer to Appendix B, Settings for Supported
PTZ Cameras, for default settings of the supported PTZ cameras.
Custom command
VPort 2140 Video Server provides 5 custom commands in addition to the general pan, tilt, zoom,
and preset functions. Administrators can click on Custom Command to configure, 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
send them out through the serial port. For instance, a text string of 8101ABCDEF 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.
