Crestron C2N-CAMIDSPT
Operations Guide - DOC. 6262A
Camera Interface, Digital Servo Pan Tilt Head
NOTE: Adjustable stops must be properly installed prior to calibration or operation
of the CAMIDSPT.
1. Apply Cresnet power to the CAMIDSPT, and use the mini joystick to
adjust the pan and tilt discs away from their default positions adjacent
to the fixed hard stops.
2. Install both pan and tilt adjustable stops by inserting the nut portions
into the slots of the rotating discs; move them away from the slot and
tighten the screws just enough to keep them from sliding.
3. Slowly rotate the camera/lens assembly to the desired left-pan limit.
Slide the closest adjustable stop until it engages the pan hard stop;
tighten the locking screw.
4. Slowly rotate the camera/lens assembly to the desired right-pan limit.
Slide the other adjustable stop until it engages the pan hard stop;
tighten the locking screw.
5. Slowly rotate the camera/lens assembly to the desired up-tilt limit.
Slide the closest adjustable stop until it engages the tilt hard stop;
tighten the locking screw.
6. Slowly rotate the camera/lens assembly to the desired down-tilt limit.
Slide the other adjustable stop until it engages the tilt hard stop; tighten
the locking screw.
7. Verify the stop positions at slow speeds and then at full speed to ensure
proper settings.
NOTE: Hard stops should not be set any closer to the pan and tilt home positions
than ±30 degrees. Hard stops set closer will prevent the unit from executing the
power-up homing routine. Dimples on each rotating disc line up with dimples on the
unit housing when the unit is in home position.
8. Cycle power to the CAMIDSPT—the unit will go through its
initialization motions. The pan function drives the unit to the right until
the adjustable stop meets the fixed hard stop. It then backs up 2-3
degrees and sets a software stop (soft stop). The unit performs the same
operation for the pan left and tilt up and down actions. When all four
soft stops are set, the unit returns to its default startup position (home
position if no user program is running). The soft stops protect the unit
and the camera/lens assembly from jarring during extreme pan and tilt
excursions.
Calibration
The CAMIDSPT is calibrated at the factory and requires no periodic calibration.
However, if the mini joystick is used to adjust the position of the CAMIDSPT after
the limit stops have been set, the next time power to the CAMIDSPT is cycled, the
unit will go through a self-calibration exercise. This is automatic and requires no
operator intervention.
During self-calibration, the unit will automatically pan and tilt slowly until it locates
hard stops, and then set soft stops three degrees away from the hard stops. This
prevents the unit from hitting the hardstops during normal use. The process may take
up to five minutes if all hardstops are set near the maximum limits of travel.
