also determines the order in which fixtures will show up whenever the
system presents a list of fixtures to choose from. Three IDs are always
the same: ID=0 is “unload all”, ID=1 is “all calibrated followspots” and
ID=2 is “all fixtures”. The rest of the ID s are assigned sequentially as
you add fixtures or groups.
Once you are finished defining all the fixtures and groups it is a good
idea to press the “Auto #IDs” button. This allows the system to logically
organize the IDs by giving lower IDs to groups, then to followspots and
finally to fixtures without pan and tilt.
Followspot calibration
The TrackPod needs to know the exact position and orientation of any
fixture that you want to convert into a followspot. You may enter this
information manually, but this can be a tedious procedure, particularly if
your fixture is difficult to reach or if you have several fixtures to
measure. Consequently, an automatic calibration routine has been
implemented for your convenience.
The automatic calibration method involves pointing the lights to five
marks on the stage floor, called followspot calibration points. The
procedure can be performed directly from the TrackPod controller or
from the PC software. One advantage of calibrating fixtures from the
TrackPod controller is that usually it is located close to the stage so it is
easier to see if the beams are directed at the stagemarks. On the other
hand, if you would like to calibrate many fixtures at once doing it from
the PC might be preferable. Here is how to do it with both methods:
Calibrating followspots from the TrackPod
Starting on the first screen that appears on the TrackPod display, do the
following:
• Press number 2 to select the option “Calibration”.
• Press 2 “Fixture” to select a fixture Calibration.
• In this next screen you have to decide which points of the stage to use
for the automatic calibration. You can either reuse the same stagemarks
that you already measured when you calibrated the TrackPod (see
Figure 5) or you can define new ones.
