|
The 16 bit analog outputs are provided as a differential signal for the X, Y and Z channels via the 10-pin connector SV1. For operation an external +/- 15 V supply must be connected. Configuration of the channels to either +/-5 V or +/- 10 V output range is possible as is the delivery of 15 mA output current.
|
The negative signals are used for scan heads with differential inputs. When using a scan head without differential inputs the positive signals are used in respect to ground (pin 6 or 10 AGND). When using the differential outputs signals with a scanner without differential inputs the scanning field will enlarge to the double size. |
