GPIB Device Simulator EPROM
GPIB Device Simulator EPROM
You can simulate the operation of a GPIB instrument by replacing the
EPROM inside a GPIB-232CT with the GPIB Device Simulator EPROM
(part number 702295-01). The GPIB-232CT will then act as a GPIB
instrument.
The Simulator functions like a GPIB oscilloscope in that it is capable of
returning waveforms in different configurations: ASCII, 8 -bit unsigned
binary, and 16-bit signed binary. It is also capable of returning single values
in ASCII such as those returned by a multimeter.
Setting the Address
The default address of the GPIB Device Simulator EPROM is set using the
first five switches of the U20 dip switch inside the GPIB-232CT. All other
switch settings are ignored.
The first 5 switches set the address. Switch 1 is the least significant bit
(LSB) and switch 5 is the most significant bit (MSB). Figure 1 shows an
example of the Simulator set to address 3.

Figure 1. GPIB Device Simulator Set to Address 3
You change the address using the dip switches or by the sending the
Simulator the
SADDR primary
,
secondary
command. For example,
SADDR 1
sets the Simulator to address 1, and
SADDR 2
,
4
sets the
Simulator to primary address 2 and secondary address 4.
