Interface Operation
The 6000 instrument family has optional IEEE488 and RS232 interfaces, which may
be configured to allow the instrument to be both controlled and interrogated by a
computer.
Both interfaces operate in a similar manner, using the same command set. There are
two operational differences between these interfaces:
•
The ability of the IEEE488 interface to switch between remote and local
command states, which the RS232 interface does not offer; and
•
The ability of the controller to continuously read the same data from the
IEEE488 interface, where as the controller must prompt the instrument to
transmit the desired data from the RS232 interface each time.
Throughout this section it is assumed that you are conversant with manual operation
of the instrument, and with the methods of operating the controller for the particular
interface being used.
RS232 Data Format Selection
Ensure that the computer connected to the RS232 port is set to the same baud rate as
the instrument’s serial port, 8 bit data with no parity, 1 stop bit and 1 start bit. For
normal operation, select the highest (38400 baud) rate.
Note that some IBM PC compatible computers do not operate correctly at the highest
baud speed, particularly when operating in a multi-tasking environment. To reduce
data transfer error rates you can decrease the selected baud rate, especially when
your operating environment has severe interference; when you are using long cable
lengths; or when you are unsure whether the computer is capable of this highest rate.
