Setting the HP-IB
Address
Note
In remote mode, all HP 8112A settings, except, EXT INPUT trigger
level, are programmable via the HP-IB. The HP 8112A also provides
error messages and can report operating parameters when requested
by the controller.
This chapter describes the valid programming mnemonics and syntax
for the HP 8112A. Example program statemen.ts are based on HP
BASIC 5.0/5.1 for the HP 9000 Series 200/300 controllers. Example
program statements also assume that the instrument HP-IB address
is 12 decimal.
This manual does not discuss the HP-IB protocol or hardware. For
detailed information on the HP-IB refer to any of the following
publications:
IEEE Interface Standard 488-1975

The HP 8112A's HP-IB address is set at the factory to 12 decimal.
The address is stored in the instrument's RAM, along with the
current instrument settings.
immediately after switching the instrument on. Pressing the (LCL)
key at any other time displays the current address while the key is
depressed, but no change is possible.
When allocating HP-IB addresses make sure no instruments on the
n
bus have the same address.
If the RAM battery fails, the HP-IB address is set to 12 when the
n
instrument is switched on.
To change the instrument's HP-IB address:
1. Switch the instrument on.
2. If the instrument is NOT in NORM trigger mode:
a. Select NORM trigger mode.
b. Switch the instrument off and on again.
3. Press the @ key. The current HP-IB address is displayed on the
frontpanel.
4. Use the vernier keys to change the address.
