The control is achieved with Bit 7 of the parallel port output bits, as shown in
Fig.4.6. The turntable should be connected to the parallel port of the computer by
means of a cable defined as follows:
PC side DB25 male ET/ST side DB9 male
Pin 9 <-----------------------> Pin 2
Pin 22 <-----------------------> Pin 4
All other pins unconnected
With the QCBox5 selected the control is achieved with Bit 5 of the QC Box output
port, the turntable should be connected to the QC Box V output port by means of a
cable defined as follows:
QCBox5 side DB25 male ET/ST side DB9 male
Pin 6 <-----------------------> Pin 2
Pin 14 <-----------------------> Pin 4
All other pins unconnected
The cable should be connected as in the following figure.

Inside the Turntable Option panel it is possible to set its Resolution (in degrees)
and Speed (in rotations per minute); the combination of these settings give the
software an indication about how much time to wait after the controlling pulse is
output.
Manual
For the azimuth angle only is it possible to choose the “Manual” turntable. This
means that the azimuth rotation of the loudspeaker under test must be managed
manually. Instead of automatically control the turntable, the software display a
pop-up message to the operator and wait for the completion of the manual rotation.
Please refer to chapter 12 for further information on polar measurement sets.
