To switch fader pages simply press the asterisk key followed by the
number from 0 to 9 that corresponds to the desired page number. The
faders will not be asserted until they are moved slightly. To temporarily
“blind” the followspots press the “c” clear button in the keypad, as you
press it the followspots blackout and you may point at a different place.
To blind a fader press the blind button on top of the fader, this will allow
the operator to set a fader without asserting it and snap the value by
unblinding the fader. In general, if the red LED is not on for a fader then
it does not have control of any parameter.
If during a show the TrackPod is moved from its calibrated position you
may quickly calibrate it again (if the preferences screen grants calibra-
tion priviledges) by pressing the cancel button, which takes you to the
main launch pad.
Example
Here are the necessary steps to have a TrackPod control pan and tilt for
a number of lights to follow a performer, with a few DMX channels
controlled by the faders and the rest by the main lighting board:
1. Install the card in the PC and connect its DMX IN and OUT links to
the board and the lights respectively (see pages 7 and 17).
2. Assemble the TrackPod and connect it to the card’s TrackPod serial
link (see pages 8 to 12)
3. Power and calibrate the TrackPod (pages 13 to 16).
4. Define and calibrate your lights (pages 18 to 21).
5. Press the Start playback button
6. Press 1 in the numeric keypad and OK to load all followspots.
7. Bring up the first fader, corresponding to intensity, to see the beam.
About sighting devices
To calculate 3D position, it is essential that the TrackPod’s head plate be
aligned with the performer. While it may be easy to follow a performer
simply by looking at the followspot beams or the shadows cast, we
recommend using a sighting device for precise, reliable work. This way,
operators concentrate on following performers by targeting them with
the viewing device, which functions as the main tracking reference.
There are two common sighting devices used: video cameras and reflex
finders.
