Configuring Serial Ports
To configure serial ports on a VAU, click on the VAU in the directory tree and
select the Serial Ports tab. To activate a COM port, highlight it and click Add.
Then highlight it in the assigned ports list and enter serial input information on
the following five tabs:
•
General. This tab (see Figure 3) requires the following information:
•
Interface Type— either Monitor, Card Reader, or PTZ.
•
PTZ Type— the make and model of the PTZ camera connected to
the selected port (if PTZ is selected for the Interface Type). Select
the type from the drop-down list; only one PTZ type can be
selected per COM port. To update the drop-down list, click Get
Types every time you want to configure the PTZ type.
•
Maximum Line Size— the maximum size of a string coming
from a device. A string longer than this many characters usually
indicates an error.
•
End of Line Characters— a character, such as a carriage return,
that indicates a line is complete.
•
Description— a description of the COM port.
•
Active— activates the COM port.
