The CVIM2 system has four RS–232 serial ports, which are listed as follows
in the setup panel:
Module I/O Port A
,
Module I/O Port B
,
System I/O
Port A
, and
System I/O Port B
. All of these ports are accessed through the
physical
Module I/O
and
System I/O
ports on the CVIM2 front panel.
The example in Figure 10.12 illustrates selecting one of the port setup panels,
in this case, the
Module I/O Port A
setup panel. To configure this serial port,
first select its intended use (
ASCII
,
Mouse
,
Keyboard
, or
DF1
) by picking
(highlighting) one. Here is a brief description of the applicability of each of
the four selections:
•
ASCII –– Select
ASCII
when using the RS–232 port to transfer data to
and from devices using the ASCII protocol.
•
Mouse –– Select
Mouse
when the port is dedicated to a serial mouse.
•
Keyboard –– Select
Keyboard
when connecting an external RS–232
keyboard to the port. This can be used to input data when the graphical
keyboard or calculator is on the screen.
•
DF1 –– Select
DF1
when using the RS–232 port to transfer data to and
from devices using Allen–Bradley’s DF1 communication protocol.
Then, choose the appropriate values from the selections alongside each of the
four parameters (baud rate, number of data bits, parity, and number of stop
bits), according to the requirements of the equipment to which the port is
connected.
