The com33v utility can be used to back up and restore files from
the UP3300.

with this program. These will be displayed on your computer when
running it.

Follow this guide to use the Com33v Utility.

1. Copy the COM33V onto your computer.

2. You may need to edit your config.sys file to contain the following
line: -
DEVICE=C:\WINDOWS\COMMAND\ANSI.SYS

ANSI.SYS will allow the text of contents to be correctly presented
on your computer screen.
(If you do not have the file ANSI.SYS in the windows\command
directory you will have to find this from another place).

4. To run the utilities enter COM33V from the relevant location.

5. A Menu will appear on the computer screen.

6. The first thing to check is the RS-232 initial Preset.
(Select item [0] from the menu).

7. When you first run this program the baud rate setting will default
to 9600. To change these from the set up screen select Execute
No then change the Baud Rate to 38400.

8.You may also want to change Packet Display for Send/Receive.
(This will display the data on your computer screen as it is being
transferred).
All other settings can remain the same.
