Introduction Introduction The AXB-PT10 PosiTrack 10, AXB-PT15 PosiTrack 15, 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. All controllers contain on-board intelligence for consistent motion and lens control.
Introduction Specifications The following table lists the specifications for all PosiTrack units. Specifications Dimensions (HWD): AXB-PT10 Camera controller: 5.85" x 5.20" x 4.92" (14.86 cm x 13.22 cm x 14.70 cm) Camera mount: 0.65" x 2.26" x 3.23" (1.75 cm x 5.74 cm x 8.21 cm) Cradle support bracket: 3.64" x 5.50" x 0.20" (9.25 cm x 13.97 cm x 0.51 cm) Dimensions (HWD): AXB-PT15 Camera controller: 6.43" x 5.61" x 5.38" (16.32 cm x 14.25 cm x 13.67 cm) Camera mount: 0.65" x 2.26" x 3.23" (1.75 cm x 5.
Introduction 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.
Introduction Speed mode moves the lens when the voltage deviates from the center point of its range. The farther the voltage moves away from the center point of reference, the faster the lens motor moves. The lens must have POT outputs when recalling a preset in this mode,. The outputs pass to the PosiTrack unit, and when the received voltage level matches the level stored in the preset, the voltage returns to zero. Servomotor speed mode lenses not having POT outputs do not have preset recall capability.
