APPENDIX C
DEC LSI 11
The following
program sends a command string to the Model 194 from a DEC LSI 11 minicom-
puter and displays the instrument
reading string on the DEC CRT terminal.
The LSI 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.
1. Using the front panel program feature, set the primary
address of the Model 194 to Y).
2. With the power off, connect the Model 194 to the IBV 11 IEEE-488 interface cable.
3. Enter the program below, using the editor under RT 11 and the name IEEEFOR.
4. Compile using the FORTRAN compiler
as follows:
FORTRAN
IEEE.
5. Link with the system and IB libraries as follows:
LINK IEEE,IBLIB.
6. Type RUN IEEE and press the RETURN key.
7. The display will read "ENTER ADDRESS".
8. Type in Y and press the RETURN key.
9. The display will read "TEST SETUP".
10. Type in the desired command
string and press the RETURN key. For example, to program
the instrument
for the autorange and average modes, type in ROFIX and press RETURN.
11. The instrument
data string will
appear on the computer
display.
A typical
display
is:
NDCV+1,2345E+O.
