*IDN?
Identification Query
Syntax:
*IDN?
Parameters:
None
Function:
This query causes the 2835-C to return device identification information. The
information returned is manufacturer, model, serial number, and firmware
version.
Returns:
<manufacturer>,<model>,<serial>,<version>
<manufacturer> is of type <string> using the no quotes format. The 2835-C
always returns Newport Corp.
<model> is of type <string> using the no quotes format.
<serial> is of type <string> using the no quotes format. This is always a ‘0’.
<version> is of type <string> using the no quotes format. This text identifies
the internal firmware version of the 2835-C. This text consists of two sections,
separated by two underscores. The first section is the revision level, and the
second is the revision date.

*IST?
Individual Status Query
Syntax:
*IST?
Parameters:
None
Function:
This query returns the current state of the IEEE 488.1
<IST> local message. The <IST> message is generated by the parallel poll
status system. If any bit is set in the Status Byte and it’s corresponding bit is
set in the Parallel Poll Enable register, then the <IST> message is set true (a
value of 1). Otherwise the <IST> message is set false (a value of 0).
When a parallel poll is conducted with the 2835-C configured to respond to it,
the <IST> message is compared to the <S BIT> (sense bit). If they are the same
then the configured data line will be driven true in response to the parallel
poll.
Both the <S BIT> and the data line driven during a parallel poll can be selected
by the IEEE 488.1 parallel poll remote configuration command.
Returns:
<sbit>
<sbit> is of type <number> which represents the integer 0 or 1.
