Using The Radio Interface (Remote Operation)
CAUTION: Do not connect a voltage source in excess of −0.3 V (for example, −0.4 V) to any Parallel Data
pin. Also, do not connect a voltage source that exceeds 5.7 V, unless the logic voltage has been
set to a level other than the default. If the logic voltage has been set to some value other than the
default of 5.1 V, the maximum voltage that can be applied is the logic voltage plus 0.6 V. Refer
to "Setting the Radio Interface’s Logic Level" on page 409.
HP-IB Command Summary
The HP-IB command mnemonics can be found in the Programmer’s Guide, under
Radio Interface.
Inputting Data over HP-IB
Use the following commands to configure the eight least significant parallel data
bus lines as inputs by writing logic 1’s to them.
DISP RINT;RINTerface:PARallel:CONFigure #HFF (hex)
or
DISP RINT;RINTerface:PARallel:CONFigure 255 (decimal)
Use the following command to read the data on the parallel bus to the Test Set’s
internal CPU.
DISP RINT;RINTerface:PARallel:INPut:READ
Use the following command to query the data read by the READ command.
DISP RINT;RINTerface:PARallel:INPut:DATA?
If the output data lines are zero, and none of the input data lines are pulled low, the
value returned by the previous command will be 255 (decimal). Remember that
data lines not configured as inputs will still be displayed, and the value returned
will be the previous query will include all 16 data lines, some of which may be
configured as outputs.
