AXB-PT10/30 PosiTrack Camera Controllers

Servomotor driven outputs are intended to drive servo-type motors only. The outputs have very low

current (milliampere range) capability. DO NOT attempt to drive conventional motors with these

outputs or you may damage the output drivers. If you are not sure about the motor type, refer to the

Specifications section on page 1for more information.

Pan Characteristics

The pan drive has a maximum pan range of ± 174° (348° total). The maximum pan rate is 35° per

second. Pan travel is capable of being limited to a restricted range around the center of pan travel by

software limits adjustable by the programmer/end user. Pan limits refer to the horizontal range of

motion available to the PosiTrack unit. These limits are set via the Axcess program. The center

position marks the center of the range.

Setting the adjustable pan-limit stops

The Central Controller should be programmed by an AMX Axcess programmer before beginning.

Refer to the Specifications section on page 1 for more information on programming devices. To set

the adjustable pan-limit stops:

Pin 1 is not required if the lens is powered independently. Pins 12-15 are required for

Speed mode but are not required for Positional mode.

This feature is controlled by the PANJA/CAM switch on the connector panel.

If you are using firmware version 1.01, do not set a preset at the same location as a

limit stop.
