Remote Mode

When linked to a computer by RS-232-C or IEEE-488 connection, the
LDS1000 Controller communicates by ASCII messages. The buttons on the
front panel of the controller are no longer valid.
The following functions are possible:
• Reading the controller's programmed parameters.
• Modification of the integration constant.
• Transmission of instantaneous values measured.
• Acquisition in the controller's internal memory, of a number N of points,
at the frequency F.
• Acquisition in the controller's internal memory, of a number N of points,
at the frequency F, the beginning of the acquisition is started by an
external signal (Trigger).
• Acquisition in the controller's internal memory of a number N of points,
each acquisition being started by an external signal (Trigger).
Refer to the chapter entitled: "Use with a computer interface".
2.2.3

Analog Mode

Analog outputs are only available on models that are equipped with this
option. This must be specified at the time of ordering.
There are two voltages at the analog outputs that are respectively propor-
tional to the angular measurements Y and Z of the equipment.
This enables:
• Connection to an analog acquisition chain.
• Visualization of positions on an oscilloscope.
• Use of the LDS-Vector autocollimator for analog controls.
These outputs are obtained by a digital/analog conversion of the values
calculated by the controller.
This conversion is carried out in real time at a frequency of 2000 Hz.
Refer to the chapter entitled: "Off-line use".
