Cornerstone System Commands
{INFO?} [LOCAL]
Query for basic instrument information. Generates the same response as the GPIB specific *IDN?
That response is “Oriel, Model 74100 Cornerstone 260,SNXXX,VYY.YY.YY” where XXX is the
unit's serial number and YY.YY.YY is the version number for internal firmware. This information is
displayed for 3 seconds when [LOCAL] is pressed on the Hand Controller. Model 74100 is
displayed for RS232/GPIB instruments. Model 74125 is displayed for USB instruments.
HANDSHAKE X {HANDSHAKE?}
This command turns Handshake Mode on and off. Setting the parameter “X” to “1” causes
Cornerstone to acknowledge command completion according to the description given in
5.1.2 Standard Mode. Setting the parameter to “0” returns the Cornerstone to normal operation
according to the description given in the section in this manual entitled Standard Mode. The
response to the query HANDSHAKE? is the single integer describing the current mode, “0” or “1”.
{STB?}
Use this query to check for Cornerstone error conditions. The response will be “32” when an error
occurred or “00” when no error is present. Reading this code clears the status byte. Further
information can be obtained using the ERROR? query below. A detailed discussion of error
handling is provided in this user’s manual.
{ERROR?}
Use this query to obtain further information about an error state reported in the Status byte. The
response will be an integer from 0 through 9. The definition of each error code and a detailed
discussion of error handling are provided in this user’s manual.
ADDRESS XX {ADDRESS?}
Use this command to change the IEEE-488 primary address for the Cornerstone if the default
address (4) conflicts with another instrument in the laboratory. Turn off the other instrument(s),
establish communication with Cornerstone, and then send this command with the integer
parameter from 1 to 30. If successful, the address change takes place immediately and any further
communication using the previous address will cause an IEEE-488 error. If unsuccessful, an error
will be reported in the Status byte.
