3.7 Uploading and Downloading the Configuration File
ProSoft modules are shipped with a pre-loaded configuration file. In order to edit
this file, you may transfer the file from the module to your PC or locate and load
the file from the distribution CD-ROM supplied with the module. After editing, you
must transfer the file back to the module for your changes to take effect.
This section describes these procedures.
Important: The illustrations of configuration/debug menus in this section are intended as a general
guide and may not exactly match the configuration/debug menus in your own module. For specific
information about the configuration/debug menus in your module, refer to The Configuration/Debug
Menu (page 45).
3.7.1 Required Hardware
You can connect directly from your PC’s serial port to the serial port on the
module to view configuration information, perform maintenance, and send or
receive configuration files.
ProSoft Technology recommends the following minimum hardware to connect
your PC to the module:
80486 based processor (Pentium preferred)
1 megabyte of memory
At least one UART hardware-based serial communications port available.
USB-based virtual UART systems (USB to serial port adapters) often do not
function reliably, especially during binary file transfers, such as when
uploading/downloading configuration files or module firmware upgrades.
3.7.2 Required Software
In order to send and receive data over the serial port (COM port) on your
computer to the module, you must use a communication program (terminal
emulator).
A simple communication program called HyperTerminal is pre-installed with
recent versions of Microsoft Windows operating systems. If you are connecting
from a machine running DOS, you must obtain and install a compatible
communication program. The following table lists communication programs that
have been tested by ProSoft Technology.
DOS ProComm, as well as several other terminal emulation programs
Windows 3.1 Terminal
Windows 95/98 HyperTerminal
Windows NT/2000/XP HyperTerminal
The module uses the Ymodem file transfer protocol to send and receive
configuration files from your module. If you use a communication program that is
not on the list above, please be sure that it supports Ymodem file transfers.
