Figure 17.
6. Mount the elbow assembly to the back of the display by sliding the mounting bolts through
the arm mounting assembly.
7. Place washers on all four mounting bolts.
8. Securely faster a nut on each mounting bolt.
9. Fasten a second nut on each mounting bolt. The second nut serves as a lock nut to secure the
first nut.
10. Slide the webcam arm into the lower part of the elbow arm assembly. The webcam arm slides
12" into the elbow assembly.
11. Ensure the webcam is on the top of the webcam arm and tighten the arm set bolts.
• For a 10' arm, the webcam arm bolts must feed through the pivoting arm, the 6' arm
section and the 10' arm section. This will set the webcam 10' from the display face.
• For a 15' arm, insert one set of bolts through the pivoting arm and the 6' arm section. A
second set of bolts is inserted on the end of the 6' arm section away from the display face
and at the base of the 10' arm section. This will set the webcam 15' from the display face.
12. Tighten all mounting and webcam assembly bolts.
13. Insert the handle to the top of the vertical tube and fasten with a
clevis pin.
14. Connect the webcam cable to the Webcam 1 connection below the
power entrance box on the back of the display.
15. Secure the green webcam grounding wire to the grounding lug
along the perimeter of the display back. Refer to
Figure 18.
16. Neatly secure excess grounding wire with cable ties.
17. Ensure all webcam and webcam mounting bolts are secure prior to
hanging the display.
18. After hanging the display, connecting display power, and starting
the display, call Daktronics NOC and have a technician verify
they can detect the video server. If the video server is not detected,
ensure the power and signal cables are securely attached to the
camera and display. Make sure the video server has power and is
connected with Cat-5e cable to the network switch on the router.
19. Work with the NOC to ensure the camera is aligned properly. If
adjustment is required, pivot the arm to the display face and adjust
as needed.
Retracting the Webcam Arm
1. To retract the webcam arm, remove the three short bolts from the top of the elbow assembly.
Note: Do not remove the long bolts.
2. Use the handle to carefully pivot the webcam arm to the front catwalk.
Note: Verify that the power and signal cables are not getting pinched when pivoting the
webcam arm.
3. Return the webcam arm to the original position when done servicing the webcam arm.
4. Replace and tighten the three short bolts.
5. Work with Daktronics NOC to verify the webcam is focused and functioning properly.
