7.7 IEEE Address Selection
SW3-1 through SW3-5 select the IEEE bus address of the Micro488/EX when in
the Peripheral Pass-Thru mode. The address is selected by simple binary weighting
with SW3-1 being the least significant bit and SW3-5 the most significant. The
following figure shows the IEEE address of the Micro488/EX set to 10.

7.7.1 Listen Only Mode
Listen Only is a special type of Peripheral operation. In the Listen
Only mode the Micro488/EX accepts all data transmitted on the bus and
transfers it out its serial port. The Micro488/EX is set to Listen Only mode
by setting its address to 31 (switches SW3-1 through SW3-5 all open).
