6.4.5 IEEE-488 Instrument Address Selection
The instrument address is set manually using an eight way miniature
switch near the interface connector on the rear panel. This DIP switch is nor-
mally marked with A0 to A7 to identify the proper switch. In our system, we refer
A0 as switch 1 and an A7 as switch 8. The OPEN (OFF) condition of the
switches will simulate logic 1 and CLOSE (ON) condition will simulate logic 0.
These states are marked on the panel as ON (0) and OFF (1).
Five of the switches (A0 to A4) are used to set the address using the
binary code. This enables any address in the range 00 (00 HEX) to 31 (1F
HEX) to be used. E.g. 11010 is address 26 (1A HEX).
The switch no A5 is not used. The remaining two switches (A6, A7) are
used to say whether the installed IEEE-488 Interface card has to be honored or
not. In easy terms, if switches A6 and A7 are CLOSED (ON) simultaneously, the
installed IEEE-488 Interface card is ENABLED. If switches A6 and A7 are not
simultaneously CLOSED (ON), then the IEEE-488 Interface card will be DIS-
ABLED even if the address is set properly.
NOTE:
THE CONFIGURATION OF IEEE-488 INTERFACE CARD AND THE ADDRESS
SETTING OF THE INSTRUMENT HAS TO BE DONE BEFORE THE INSTRUMENT
IS SWITCHED ON. AFTER POWER ON, CHANGING OF THE SWITCH SETTINGS
ON THE IEEE-488 INTERFACE CARD WILL NOT HAVE ANY EFFECT ON RE-
MOTE OPERATION OF THE INSTRUMENT.
