Special Considerations for Using the RS-232 Port
for Uploading Programs
for Uploading Programs
The CEN-TVAV has a single RS-232 port that is used for uploading programs and
communicating with RS-232 equipment for control purposes. Since the port is
shared, the operation of the console port is slightly different from standard CNX
systems that have a dedicated RS-232 console ports. When a program is loaded into
a CEN-TVAV that uses the TVAVCOM-1 port, the program will initialize but the
shared port will still be attached to the console. The program will run normally, but
the TVAVCOM-1 port will effectively be “disconnected” from the system. This is
done so other configurations (such as uploading SIMPL+ modules, setting the IP
Table, etc.) can be done.

After the program is rebooted (using F10 in the Viewport or cycling operating
power), the shared port is taken over by the TVAVCOM-1 port (if the TVAVCOM-1
symbol is present in the program) when the SIMPL program initializes. Note that
SIMPL Windows will not convert the TVAVCOM-1 port if there are no signals or
data coded in the port, or if the symbol is commented out. When the program
initializes, the normal TVAV bootup messages will be issued out the TVAVCOM-1
port, i.e.:

If there is a device hooked up to the TVAVCOM-1 port, the bootup message may be
treated as false characters and cause device errors. It is possible to set the baud rate
to DISABLE (pressing F8 while in the Viewport and selecting DISABLE) for the
console port. This will cause the initial bootup message to not be displayed. In order
to obtain communications with the CEN-TVAV through the RS-232 port, the
following methods can be used:
