No PTZ control in DS Admin when DS ControlPoint is running.

Issue

PTZ control works on client machines and in DS Admin until DS ControlPoint is opened on the DVR/HVR, once DS ControlPoint is launched all PTZ control stops functioning.

Product Line

Pelco Video Management

Environment

  • DS ControlPoint
  • Digital Sentry
  • DSSRV
  • Serial RS 232/422

Cause

On the DS DVR/HVR, COM1 is being used to transmit the PTZ control data, when the DS ControlPoint application opens it allocates serial port COM1 looking for data from KBD300a controllers.

Resolution


Change the COM port DS ControlPoint uses for KBD300a communication

  1. On the DS DVR/HVR, click on Start > Search Bar or Run > type in %appdata%\pelco and press ENTER.
     
  2. Right-click on the ControlPointCache.xml file and select Edit.
     
  3. Press CTRL + F and type in COM1, click the Find Next button.
     
  4. The COM1 entry should now be highlighted, close the Find window.
     
  5. Change the COM number to a value not being used by another serial port, usually something like 20 is safe.
    Example COM20


     
  6. Click on File > Save (Ctrl + S)
     
  7. Close Notepad.
     
  8. Run DS ControlPoint and verify PTZ control still functions.
