Interfaces
The minimum requirement for configuring your system is to make certain that your IEEE 488.2
interface board or module is selected under “Device Type.” The default settings in all of the other
fields match those of the interface as shipped from the factory. If you are unsure of a setting, it is
recommended that you leave it as is.
External Devices
Within your IEEE 488.2 application program, devices on the bus are accessed by name. These names
must be created and configured within the
CONFIG program. After configuring your interface
parameters, press to open the External Devices window. All configured devices will be
accessible in your application program via the OpenName command. For more details, refer to the
topic “Configuration of IEEE 488 External Devices” found later in this Sub-Chapter.
Opening the Configuration Utility
In general, all Driver488/SUB configuration utility screens have three main windows: the “name” of
the interfaces or devices on the left, the “configuration” window on the right, and the “instruction”
window at the bottom of the screen. Based on current cursor position, the valid keys for each window
will display in the Instructions box.
To begin the interface configuration, move the cursor in the name window to select an interface
description for modification. (Interfaces can be added or deleted using
and .) Notice
moving the cursor up and down the list of interfaces or devices in the left window changes the
parameters in the configuration window. The configuration fields always correspond with the currently
selected interface and device type.
Once all modifications have been made to the configuration screen, must be pressed to accept
the changes made or can be pressed to exit without making any change. Additional function keys
allow the user to continue onto the configuration of external devices via or to view a graphic
representation of the interface card with the selected settings via .
Configuration of IEEE 488 Interfaces
The Driver488/SUB supports
two types of interfaces: IEEE
and Serial (COM). The
following Driver488/SUB
figure displays the
configuration screen of an
MP488CT IEEE 488.2
interface.
To add another IEEE interface,
select
. For additional
information on using more than
one interface, refer to the final
topic “Multiple Interface
Management” in the Sub-
Chapter “Installation &
Configuration” of Chapter 8.
Once an interface is selected,
the fields and default entries
which display in the
configuration window depend
on the device type specified. The configuration parameters of the IEEE interface, shown in the figure,
are as follows:
