6. INTERFACE UNIT
(24) PR
(a) Format: PR
(b) Description: • Dedicated command for GP-IB.
• Used to print the measured data on the optional printer.
• It is necessary to set the RS-232C port to the printer port in the basic setup
in advance. Without this setup, designating this command results in ER6.
(c) Example: Reception command PR
Response command None (printed on the printer)
(25) SRQ, NSRQ
(a) Format: SRQ, NSRQ
(b) Description: • Dedicated command for GP-IB.
• This is used to set up the service request transmission, according to the data
condition or command receiving condition.
• Using an SRQ, the interface unit performs a service request to the controller.
With the NSRQ, the interface will not perform service request.
• A response command will not be issued to this SRQ. Acknowledge if the
response is OK with the SRQ status byte.
• With the NSRQ, the interface will not perform service request. It will only
respond with an "OK" command.
(26) Timing signal
If the measuring operation is interrupted by a command from the I/O interface or key operation,
an ER7 will be responded to the RS-232C/GP-IB interface.
This can be used as a timing signal to start a sequencer, etc.
