A.8 External Scanner Control
NOTE!
If the scanning head is equipped with the External Scanner Control option (EXT), it is not
possible to operate the optional pan-tilt head.
By default, in the scanning head the DAC output signals are connected
directly to the control inputs of the scanners. If the scanning head is provided
with the EXT option (external scanner control), the DAC output signals and
the control inputs of the scanners are available at the OPTION jack. In this
case the scanners only move if a voltage is created at the control inputs. The
scanning angles are deflected according to the voltage applied to the control
inputs. The voltages must be within the range of ±5 V. The relationship
between applied voltage and the deflection angles is:
Cabling
You have to assemble the provided 8-pin DIN circular plug before you can use
the external scanner control. Plug the 8-pin DIN circular plugs into the
OPTION 8-pin circular jacks on the back of the scanning heads.
The pin configuration of the 8-pin DIN circular plug is shown in the following
figure as well as in the following table.
