PTZ Port
A PTZ port is located on the VPort 251’s bottom panel. The port is used to
connect to 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 the terminal block, with pin
assignments as shown in the following table:

Hardware Reset
The RESET button restores the system to the factory default settings. When the
system fails to install properly or operates abnormally, use a pointed object,
such as a straightened paper clip or toothpick, to hold the reset button down for
several seconds. When the STAT LED blinks red, release the button. The
POST process will run and the VPort will reboot. The STAT LED will glow a
steady green when the VPort has finished rebooting.
