Using IBWRT
The IBWRT command sends data from one GPIB device to another. For
example, to send a data string from the computer to a device called
dev1, the following command would suffice:
Example:
dev1:
[0100] (cmpl)
count: 6
ibwrt "F3R5T1"
This command sends the string "F3R5T1" to device called dev1. The
returned Status Word [0100] indicates a successful I/O completion,
while the Byte Count indicates that all six characters were sent from
the computer and received by the device.
Using IBRD
The IBRD command causes a GPIB device to receive data from another
GPIB device. The following example illustrates the use of the IBRD
function.
Example:
