Interface Operation

Reading Data Via an Interface
With either interface, you can read the data presently being displayed on the front
panel of the 2000 instrument. With the 2000-RS-BAT interface this is achieved
by transmitting the @ character to the 2000 instrument, with the IE-BAT inter-
face this is achieved by simply reading the instrument. In either case, the instru-
ment responds by sending a single
space
character, followed by the 16 character
display string, and terminating by the
carriage return
and
line feed
characters
(with the IE-BAT interface this last character is sent with the
EOI
line asserted).
Sending Data Via an Interface
Both the RS-BAT and IE-BAT interfaces operate similarly with regards to send-
ing data to the instrument. The only difference is the requirement to place the
instrument in the “REMOTE”
state when using the IE-BAT interface. Characters
transmitted to the interface are stored in a buffer until a
line feed
character is re-
ceived, or until a character with the EOI line is asserted (in the IE-BAT inter-
face).The received characters are then decoded and actioned.
Up to 30 characters may be stored in the
receive buffer
, which may contain more
than one complete command string type, as desired.
Command Set for the 2000 Instrument
The 2000I, 2000M, 2000IN or 2000MN instrument command sets are split into
two groups:
The commands, which correspond exactly to individual front panel key
presses—to allow the same procedure to be followed, whether the instru-
ment is being used locally or remotely. See Table 4
The shortcut commands—that allow certain commonly used functions to
be easily accessed by remote commands. See Table 5.
Keypress, Simulation Command Characters
The characters received from the interface that correspond to individual front
panel keys are shown in Tables 4 and 5.
