7 Remote Control
The CoBrite series operates using SCPI standard style commands which are ASCII
based and allow easy communication and interpretation with the instrument. Refer to
chapter “ Interfaces ” on how to establish communication to the ports available at the
instrument. More detailed information on SCPI syntax can be found here:
http://www.ivifoundation.org/docs/SCPI-99.PDF
7.1 Operating multiple Interface Ports
CoBrite mainframes support parallel usage of al remote-control ports available but
not multiple connections to the same port. Note that responses to commands issued
are only returned to the according port from where the command was issued.
Commands are generally executed in order of time wise arrival to the controller and
buffered into a FIFO stack. If a stack overflow occurs, an error is issued.
Note that there is not control exclusivity is given to any laser port for a specific
interface or user. Thus, commands issued to the same port by different instances
might lead to inconsistencies. It is recommended to poll current parameter status to
ensure integrity of set vs. actual parameters.
7.2 Syntax conventions for commands
7.2.1 Long and short form
The key words feature a long form and a short form. Either the short form or the long
form can be entered, other abbreviations are not permissible.
Example: STATus:QUEStionable:ENABle 1= STAT:QUES:ENAB 1
Note: The short form is marked by upper-case letters; the long form corresponds to
the complete word. Upper-case and lower-case notation only serve the above
purpose, the instrument itself does not make any difference between upper-case and
lowercase letters.
Note : All commands are case insensitive.
7.2.2 Query commands
Most commands serve a double function that allows either setting or executing a
query on a parameter.
Note : Query commands are terminat ed by a “?” character.
