5. Use a pencil to set the switches to
the desired HP-IB address and Talk Only (TON) or Listen
Only (LON) condition. The switch is illustrated in Figure 2-2. Facing the board, the left hand
switch (marked with a "5") is the most significant address bit (A5 in Table
2-2). Setting a switch
toward the printed circuit board places it in its "1" position. If the TON and LON switches are
both set
to
"l", the Talk Only setting will override.
If the address switches and the TON switch are
all
set to "l", the Modulation Analyzer will output one byte (the status byte) each measurement
cycle. (Setting
all
switches to "1" defeats HP-IB operation.)
6.
Reinstall the
top
cover by reversing the procedure in previous step 3.
7. Connect the line (Mains) power cable to the Line Power Module and reconnect the HP-IB cable
to
the HP-IB connector.
8. To confirm the address, turn on the instrument and select BUS
ADRS
(Blue Key, LOCAL). To
confirm a
t a l k
only or listen only setting, key in 21.0 SPCL. The display shows a binary number
in the form AAAAA.TLS where A A A M is the HP-IB address in binary and T,L, and S indicate
talk, listen, and service request
status.
