CONFIGURING FROM OTHER CONTROLLERS
The 4807/4867s can be configured from any GPIB bus controller by
following the steps outlined below. Use Output and Enter commands for
your GPIB Controller Card to send SCPI commands and receive responses.
The following examples use NI 488.2, ICS and HP command examples.
1.
Connect the 4807/4867 to the bus controller as directed in section
2.6. Turn the unit on.
2.
Determine the 4807/4867's GPIB address or 2307/2367's network
address by one of the following methods:
a) Use the factory default value of 4 for new units.
b)
If you do not know your unit's address, turn the unit off and back
on. The unit will display its primary address at the end of its self
test routine by blinking its LEDs. The LED bit weights are:
RDY TALK LSTN
SRQ ERR

3.
Make a list of the configuration parameters and your new setting.
Make a copy of Table 1-2 or 1-3 and note the new parameter
settings. You only have to change the parameters that are different
from the shipped (default) configuration.
4.
Verify communication with the unit by querying its IDN message.
Use the equivalent OUTPUT and ENTER type statements in your
GPIB bus controller library to send the *IDN? query to the unit and
to read its response. This example uses National Instrument
commands.
ioerr% = Send(Bd, Addr,"*IDN?", EOTMode)
Instring$ = String$(Lin, 32)
'fills the string with spaces
ioerr% =Receive(Bd, Addr, Instring$, Term)
5.
Older units may have been locked or have unrecorded or obsolete
settings. Use the CAL:LOCK command to unlock the unit and the
CAL:DEFAULT to restore the unit to the factory default settings.
