HP 3326A - Hp-Ib Address; Storage and Shipment

HP-IB Address
To achieve design performance with the HP-IB, proper voltage levels and timing rela
tionships must be maintained. If the system cable is too long, the l ines cannot be driven
properly and the system will fai l to perform (see Figure 10 for HP-IB cable lengths).
Therefore, when interconnecting an HP-IB system, it is important to observe the fol
lowing rule;
Total cable length for the system must be less than or equal
to 20 meters (65 feet) or 2 meters (6 feet) times the total number
of devices connected to the bus, whichever is less.
HP-IB ADDRESS
The HP 3326A has a factory selected address of 18. The HP-IB address of the HP 3326A
is stored in a nonvolatile memory (there are no address switches). Every device on the
HP-IB must have a unique address. The HP 3326A address can be set at any address
between 0 and 30, inclusive. When selecting an address, remember that the controller
also has an address (usually 21). To view or change the HP-IB address;
● Press the blue SHIFT key fol lowed by the LOCAL key in the HP-IB
STATUS block to display the HP-IB address.
● Enter the address with the numeric keypad. For two digit HP-IB ad
dresses, the address is set when the second digit is entered. For
one digit HP-IB address, the address is set when any units key is
pressed. Alternately, a zero can precede the single digit to form a
two digit address.
● The message “Error 20 RNGE’’ is displayed if the HP-IB address ex
ceeds 30.
