Level applications
 Touch panel joystick application: PosiTrack Levels 1 and 2 are speed type levels for both
pan and tilt. Sending a value of 0 (zero) moves the axis full speed in one direction; while
a value of 255 moves it at full speed in the opposite direction. Sending a 127 value, stops
the units’ movement.
 Pan/Tilt feedback application: PosiTrack Levels 5 and 6 are positional levels with a value
range of 0 - 65535. These two levels can be used in Axcess code to monitor the actual
pan/tilt positions or store additional presets. To recall presets in this manner, use the
’GxLxxxx’ Send Command with the values stored previously from level 5 or 6. Refer to
the Positional Commands table on page 37 for more information.
