Lens Tracking Adjustment

When connected to a monitor, the image generated by the

CobraDome camera must stay in focus during transitions from

telephoto mode to wide angle mode.

If an image losses focus during the transition from tele to wide

angle, the lens tracking needs adjustment.

1) Disconnect the 7-pin Plug connector from the 7-pin Ramp

connector ① (see Figure 24).

2) Remove the four screws securing the printed circuit board

cover to the top of the 1273 chassis, exposing the 8-position

DIP switch ⑤.

3) Disable the lens motors by setting switch 3 of the 8-

position DIP switch (S1) ⑤ to the ON position (disabled).

4) Remove the four screws securing the camera shroud ② and

the lens shroud ③ to the camera/lens frame. Remove both

shrouds.

5) Loosen the lens tracking adjustment wheel set screw ④.

NOTE: Early CobraDome models use a 0.035 inch Allen-

head set screw ④ while later models use a Phillips-

head set screw ④.

6) Restore power to the CobraDome by connecting the 7-pin

Plug connector to the 7-pin Ramp connector ①.

7) Connect a monitor to the video out BNC ⑥.

8) Manually open the iris using the iris ring ⑦. Open the iris

to its maximum opening.

9) Manually retract the lens using the zoom ring ⑧. Retract

the zoom to its minimum (wide angle) magnification range.

10) Manually focus on an object as clearly as possible by

rotating the lens focus ring ⑨.

11) Manually zoom in on the object (i.e., increasing the

magnification) using the zoom ring ⑧.

12) Rotate the tracking adjustment wheel

➉

until the object

appears in focus.

13) Repeat steps 8 through 12 until the camera stays in focus

through the entire zoom range.

14) Re-tighten the tracking adjustment wheel set screw ④.

The zoom tracking adjustment is now complete.

15) Unplug the 7-pin plug connector from the 7-pin ramp

connector ①.

16) Replace the camera shroud ② and the lens shroud ③.

17) Enable the lens drive motors by setting switch 3 of the 8-

position DIP switch (S1) ⑤ to the OFF position (enabled).

18) Replace the printed circuit board cover on top of the

CobraDome chassis.

19) Restore power to the CobraDome by connecting the 7-pin

Plug connector to the 7-pin Ramp connector ①.
