LDS1000 Controller for Laser Diode Sensors
The parameters of the RS-232-C interface are the following:
• BAUD RATE Interface speed.
• MSG TERM End of message character.
• WORD LENGTH Length of the transmitted chain.
• STOP BITS Number of stop bits.
• PARITY Parity used by the interface.
6.2.2
IEEE-488 Interface
The IEEE-488 protocol is only possible when the computer is equipped with a
special card that allows IEEE-488 communication. There are several different
models available on the market. Please note that they are not compatible bet-
ween themselves. As a result, a software program written for a IEEE-488 card
of a model will not work with another IEEE-488 card.
The parameters of the IEEE-488 interface are the following:
• MSG TERM End of message character.
• PRIM ADRESS Instrument’s primary address.
• SECOND ADRESS Instrument’s secondary address.
• TIME OUT Wait time.
The IEEE-488 interface enables several different instruments to be connec-
ted to the same computer input. It is quicker than the RS-232-C interface. For
this connection, the controller operates in SRQ mode.
The parameters of the two communicating instruments must be identical to
obtain the communication (in fact the two instruments must speak the same
language in order to understand each other). The LDS1000 Controller is
considered to be a slave in the communication protocol. Its parameters
must therefore be chosen in accordance with those of the master computer.
Cf. Chapter entitled: “Off-line use”.
6.3 Controller Configuration
The LDS1000 Controller has a program and material configuration that
depends on the options chosen at the time of ordering. In particular, the
internal software version, the size of the memory installed and the installa-
tion of the analog output option represent information that is accessible in
manual mode.
Moreover, so that you can comfortably use the controller in different
atmospheres, the brightness of the light can be adjusted.
Accessible functions:
• Reading the version.
• Display brightness.
• Memory size.
• Analog output option.
Refer to the chapter: “Off-line use”.
