Introduction Introduction The AXB-PT10 PosiTrack 10 and AXB-PT30 PosiTrack 30 Camera Controllers (FIG. 1) are camera/lens controllers used for precise camera-positioning applications. Each PosiTrack unit supports both AXlink and RS-232 control protocols and connects directly to an AXlink network. The PT10 and PT30 contain onboard intelligence for consistent motion and lens control.

Introduction Lens Control Modes The Servomotor and Motor modes are two Analog Voltage Control methods available on the PosiTrack units. Servomotor Mode This method is generally used in broadcast or videoconference-style lenses. The voltage range used for servomotor style lenses is +2.5 to +7.5 VDC. These lenses can be controlled in two different modes: positional mode and speed mode. ! Positional mode is the most common Servomotor mode.
Introduction Zoom, Focus, and Iris Control Each PosiTrack unit delivers a low voltage pulse-width-modulated output for zoom, focus, and iris functions for motor mode lenses. These units are also capable of receiving reference voltage rails and sending zoom, focus, and iris control signals in response to these rails. In this setting (slideswitch configured), no active control signals will reach the lens before power (+ 12 VDC and GND) is supplied to the lens.
Pre-Installation Pre-Installation There are four SPDT slide switches in the lens control section (FIG. 3). Three of the switches toggle the lens control selection between servomotor or motor mode hardware for control of zoom, focus, and iris. The fourth selects between ± 6 VDC and ± 12 VDC control for motor mode lens functions. An SPDT switch is a Single Pole-Double Throw switch. This switch is completed at both positions. An example is the Volt switch that is active in both the 6 and 12 positions.

Pre-Installation 12 AXB-PT10/30 PosiTrack Camera Controllers
Installation Installation The PosiTrack units enable pan and tilt functionality for mounted camera/lens assemblies and provides lens control functions for teleconferencing lenses. Digital encoders are installed on both the pan and tilt drives, allowing positional feedback for presets, and to provide accurate speed control. Software adjustable stop limits are used on the pan and tilt drives to limit the range of motion.

Cradle support bracket Wire tie-mount Camera mount assembly Pedestal mount unit (PM-CAM) FIG.
Installation PT10 Camera/Lens Mounting and Balancing The camera/lens assembly should be mounted so the tilt axis is capable of going through the optical axis of the camera, assuming the optical centerline is between ½" (12.70 mm) and 5" (127.00 mm) above the mounting plane of the camera lens. The mounting platform (camera cradle) allows the camera/lens to be mounted with its center of gravity on the tilt axis. The maximum weight of the camera/lens assembly is 10 lbs. (4.54 kg).
Installation 4. Determine the center of gravity for the camera by using your finger to balance the entire camera/lens and mount. The center of gravity is the location on the long axis of the camera/ lens assembly around which the camera and mount balances. 5. Note the position of the center of gravity. 6. Place the camera/mount into the appropriate location along the camera support bracket so the camera’s center of gravity aligns with the horizontal tilt-axis, as shown in FIG. 16.
Installation 13. Support the weight of the camera cables with a wire tie attached to the wire tie mount on the lower corner of the face of the PT10 (FIG. 13). PT30 Camera/Lens Mounting and Balancing The camera/lens assembly should be mounted so the tilt axis is capable of going through the optical axis of the camera, assuming the optical centerline is between ½" (12.70 mm) and 5" (127.00 mm) above the mounting plane of the camera lens.
Installation 5. Place the assembly on the balancing beam and while maintaining the cradle centered on the pipe, slide the camera along the cradle’s grooves until the camera and cradle remain balanced on the beam (FIG. 20). Tilt-axis mounting slots FIG. 20 Balancing the camera/lens cradle assembly 6. Mount the camera as close to the tilt hub as possible to obtain a true center of gravity. 7. Secure both the camera mounting and tilt-axis screws. 8.

Installation The PosiTrack units are both powered from an optional local power supply. The wiring distances for the AXB-PT10 are based on a +12 VDC power supply and are capable of 2 A (continuous) with a maximum current of 20 amps. The wiring distances for the AXB-PT30 are based on a +12 VDC power supply and are capable of 6 A (continuous) with a maximum current of 20 amps. The PosiTrack unit provides power outputs for the camera/lens combination.
Installation 1. Unscrew the PWR and GND wires on the terminal end of the PSN6.5 2-pin cable. 2. Pair the GND wires from the PSN6.5 and the Central Controller AXlink connectors together and insert them into the clamp position for GND on the PosiTrack unit’s AXlink connector. 3. Tighten the clamp to secure the two GND wires. 4. Place the PWR wire from the PSN6.5 into the open clamp position for PWR on the PosiTrack unit’s AXlink connector. 5. Tighten the clamp to secure the PWR wire.
Installation Preparing the PosiTrack Controllers for communication The AXlink Device DIP switch is located beneath the round cover on the back of the PT10 and PT30. Set these switches to the desired device value based on the number of PosiTrack units being used in a particular system. The initial unit is defaulted with a device number of #90. Any additional units must have values that do not conflict with other PosiTrack units being used.

Installation 1. Ensure that there is enough slack in the lens, camera, and PT10/30 AXlink cables to accommodate the full range of pan motion. 2. Confirm that the necessary programming has been done to the system before beginning the installation process. 3. Mount the camera controller to the desired horizontal surface. 4. Pan the unit as far to the left as desired and enter this position into the Axcess program as the left pan-limit stop. The LEFT limit stop MUST be set left of the Home position. 5.

Upgrading the Firmware Upgrading the Firmware Your PC must be connected to the PROGRAM DB-9 connector on the Controller or camera control unit connector using a Programming Cable in order to upgrade the firmware in the panel. If power is lost during the download process, the unit powers up with the same set of code it had prior to the download. There is a small window during which a loss of power can be catastrophic.
