returns the error ENEB as soon as a program tries to access the board. The
default is
yes
for
GPIB0
and
no
for all other GPIB boards.
COM Port (Board Characteristic Only)
This field specifies the serial communications port to which the GPIB
interface is connected. COM1 through COM4 define the standard
PC-compatible serial communications ports. The Serial Port Base Addr ess
and IRQ Level fields change accordingly when you change the COM Port
Selection. If you have non-standard serial communications ports, then
modify the Serial Port Base Address and IRQ level fields separately. The
default for
GPIB0
is
COM1
.
Serial Port Base Address (Board Characteristic Only)
This field specifies the base I/O address of the serial communications port
and should only be used if you have a non-standard serial communications
port. The GPIB-232CT-A software assumes that the serial controller
hardware is compatible with the National Semiconductor INS8250 universal
asynchronous receiver/transmitter (the standard for PC-compatibles).
Serial Port IRQ Level (Board Characteristic Only)
This field specifies the IRQ level of the serial communications port and
should only be used if you have a non-standard serial communications port.
The GPIB-232CT-A software assumes that the serial controller hardware is
compatible with the National Semiconductor INS8250 universal
asynchronous receiver/transmitter (the standard for PC-compatibles).
Baud Rate (Board Characteristic Only)*
This field specifies the baud rate of the serial communications port. It
ranges from 300 baud to 38400 baud. For Windows, 38400 baud is not
supported and 19200 baud does not work properly in all configurations; you
should use the default rate of 9600 baud.
