APPENDIX B
DEC LSI 11
The following program sends a command
string to the Model 199 from a DEC LSI 11 minicom-
puter and displays the instrument
reading string on the DEC CRT terminal. The IS1 11 must be
configured
with 16K words of RAM and an IBV 11 IEEE-488 interface.
The software must be con-
figured with the IB software as well as FORTRAN
and the RT 11 operating
system.
DIRECTIONS
1. From the front panel program feature, set the primary address of the Model 199~fo 26.
2. With the power off, connect the Model 199 to the IEG' 11 IEEE-488 interface cable.
3. Enter the program below, using the editor
under
RT II and the name IEEE.FOR.
4. Compile using the FORTRAN
compiler
as follows: FORTRAN
IEEE.
5. Link with the system and IB libraries
as follows: LINK IEEE,IBLIL%
6. Type RUN IEEE and press the RETURN
key.
7. The display will read "ENTER ADDRESS".
8. Type in 26 and press the RETURN
key.
9. The display will read "TEST SETLP'.
10. Type in the desired command
string and press the RETURN
key. For example,
to program
the instrument
for ACV and
autorange,
types in FlROX and press RETURN.
11. The
instrument
data string will, appear
on the computer
display.
A typical
display
is:
NACV+O.OC0lOOE+O.
