The COM port and camera need to be configured for PTZ control on the DS Xpress.


Verify the wiring from the DS Xpress/ RealVue Xpress for PTZ control

  1. Connect the wire pair from the camera to the DS system on T+ and T- , the polarity needs to stay aligned.

    Example: DS System T+ connects to R+ on the camera. Pelco PTZ cameras use RS-422 when connecting to Pelco equipment.

    1. Open Device Manager (Right Click My Computer on Desktop > Select Manage > Select Device Manager)
    2. Go to Ports (COM & LPT), locate USB - 1st Serial Port (COM17)
    3. Close Device Manager

    1. Open DS Admin (Start > All Programs > Pelco > DS Admin)
    2. Navigate Available Systems > VAU and then click on the system listed directly under the VAU folder like a hyper-link (do not expand but click on - hand icon).
    3. The VAU configuration tabs will be loaded in the right hand window, click on the Serial Ports tab.
    4. Add the COM ports that are assigned to Ports (COM & LPT) to the Assigned COM Ports (Note: COM port will be plus 1 of USB - 1st Serial Port, example if COM17 was detected use COM 18)
    5. Highlight the first COM port listed in Assigned COM Ports and then select the General tab.
    6. Change the Interface Type: to "PTZ" and the PTZ Type: to "Your cameras protocol - Pelco usually = Pelco D, No Parity", may need to click the "Get Types" button to populate a list of options.  Leave the rest of the options to defaults and then check the box for Active.

    7. Click Save.
    8. Repeat steps 5 - 7 for each additional COM port listed in the Assigned COM Ports window.

    2. Locate the DigitalSENTRY VideoServer Service, right-click and select Restart.

  8. Click the drop down menu under "Camera Connected to port" and select the first COM port assigned to the DS System wired for PTZ control.  Select the "Available Address" which matches the camera's configured address.
  9. Click Save.
