AXB-PT10/30 PosiTrack Camera Controllers
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 (slide-
switch configured), no active control signals will reach the lens before power (+ 12 VDC and
GND) is supplied to the lens. This motor mode applies to the control of the Fujinon and Canon
teleconferencing lenses. During preset recall operation, these outputs are synchronized with the pan
and tilt motions. Refer to the PosiTrack Unit Lens Compatibility table on page 1. Four solid state
relays are also provided to control the zoom, focus, and iris speed/position mode selection and iris
local/auto selection on the Fujinon MD series and Canon KTSA series lenses.
