Introduction

AXB-PT10/15/30 PosiTrack Camera Controllers

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. When voltage changes, the lens

moves and remains still until the voltage changes again. For example, if a lens receives a

voltage of +3 VDC, the lens moves to the corresponding position and stays there as long

as the voltage remains at +3 VDC. The movement speed of the lens motor is a function of

the PosiTrack unit’s analog output. The lens servomotor receives the preset voltage when

a preset is recalled in the positional mode.

Specifications (Cont.)

DIP Switches: • (S2) - RS-232 communication (baud rate)

• (S5) - AXlink communication (device #)

Presets: Stores up to 255 presets for pan, tilt, zoom, focus, and iris operations; 127 of

those presets return a status when queried.

Relays: Solid-state relays for servomotor lens mode control (zoom/focus speed/position

and iris local/auto)

Optical Centerline: Optical centerline is between 1/2" and 5" above the mounting plane of the cam-

era/lens (this allows the mounting of the camera/lens so that the tilt axis is

capable of going through the optical axis of the camera)

Environmental Parameters: 32° F to 120° F (0° C to 48.8° C) ambient temperature range

Enclosure: Metal with enamel and anodized matte finish

Control Panel: • RS-232 DB-9 connector (300 baud - 38.4 KB communication for camera

control)

• DB-15 high density connector (lens control)

• Lens power switch (powers or isolates the camera lens)

• AXlink 4-pin connector (provides AXlink, RS-232 stand-alone

communication, and power connection points)

Battery: Lithium battery to protect preset memory (up to 10 years)

Connectors: • 4-pin captive wire (AXlink)

• DB-15 HD 15-pin high-density (female) for lens control

• DB-9 9-pin D-sub (male) for RS-232 camera control

Optional Accessories: • CC-CAM lens control cable (specify make and model)

• CC-CAM RS-232 camera control cable (specify make and model)

• Pedestal mount (PM-CAM, PosiTrack Pedestal Mount)

• PSN2.8 Power Supply (for use with the PT10 Camera Controller)

• PSN6.5 Power Supply (for use with the PT10/15/30 Camera Controllers)

- This power supply can be used with ALL PosiTrack units

• Tripod mount (TM-CAM, PosiTrack Tripod Mount Adapter)

• Wall-mount bracket (WM-CAM, PosiTrack Wall Mount)
