• Any ASCII character sent with the EOI control line
asserted
RS-232 interface:
The CL3001 sends a Carriage Return (CR) character as the
terminator for response messages. The CL3001 recognizes the
following as terminators when encountered in incoming data:
• ASCII CR character
• ASCII LF character
e) Incoming Character Processing
The CL3001 processes all incoming data as follows:
• The most significant data bit (DIO8) is ignored
• All data is taken as 7-bit ASCII
• Lower case or upper case characters are accepted, with lower
case converted to upper case before processing
f)
Response Message Syntax
In the detailed command descriptions in section 10, the
responses from the CL3001 are described wherever appropriate.
In order to know what type of data to read in, refer to the
beginning of the response description for the command.
9.7 Checking CL3001 Status
Figure 33 shows the status registers, enable registers, and queues in
the CL3001 which indicate various conditions in the instrument.
Some registers and queues are defined by the IEEE-488.2 standard,
while the rest are specific to the CL3001. In addition to the status
registers, the Service Request (SRQ) control line and a 16-element
buffer called the Error Queue provide also status information.
