The GPIB-232CT Modes of Operation
Introduction
The GPIB-232CT is capable of operating in one of two modes:
S mode
or
G mode
. This chapter helps you determine the mode you will use and the
chapters of the manual that apply to that mode.
Choosing Between S Mode or G Mode
You will be connecting the GPIB-232CT to both a serial device and a GPIB
device. The GPIB-232CT's mode of operation is determined by the role the
serial device plays in your setup.
Is the serial device a Controller? Is it going to manage the GPIB, address
devices, and perform other GPIB Controller functions? If so, use the
GPIB-232CT in the
S mode
.
Or, is the serial device going to be only a Talker and/or Listener, where a
GPIB device(s) will manage the bus and send and receive data to and from
the serial device? If so, use the GPIB-232CT in the
G mode
.
Figure 2-1 shows the GPIB-232CT operating in the
S mode
where a
personal computer is controlling a GPIB plotter.
