Set the GPIB address
The default GPIB address is
5
. You can set the address to any number from
1
to
30
if it is unique in
the system. This address cannot conflict with an address that is assigned to another instrument or to
the GPIB controller.
GPIB controllers are usually set to
0
or
21
. To be safe, do not configure any instrument to have an
address of
21
. To change the controller address, see the documentation for the controller.
The address is saved in nonvolatile memory, so it does not change when a reset is done or when the
instrument power is turned off and then turned on again.
To set the GPIB address from the front panel:
1. Press the
MENU
key.
2. Under System, select
Communication
. The SYSTEM COMMUNICATION window opens.
3. Select the
GPIB
interface.
4. Next to Address, select the number. The Set GPIB Address dialog box is displayed.
5. Enter the address.
6. Select
OK
.
If you are using a 2281S with no front panel, you can set the GPIB address with the SCPI
command
:SYSTem:GPIB:ADDRess
.
LAN communications
The Model 2281S-20-6 comes with one standard LAN crossover cable for LAN communication.
However, you can use any standard LAN crossover cable (RJ-45, male-to-male) or straight-through
cable to connect your equipment. The instrument automatically senses which cable you have
connected.
The following figure shows the location of the LAN connection on the rear panel of the instrument.
Connect the LAN cable between this connection and the LAN connector on the computer.
