Hex File Transfers Hex is an abbreviation for hexadecimal data format. This data format is typically
used in electronic memories, including the module EEPROM and UVPROM
optional memory modules. Hex file transfers are used to upload and download hex
data to the module EEPROM or UVPROM. The primary use of hex file transfers
is to transfer the entire contents of the EEPROM from one module to the
EEPROM of another module. It can also be used to write the contents of
EEPROM to UVPROM via a PROM programmer.
Uploading Hex Files
Uploading hex files is similar to uploading program files, with a few exceptions.
Make sure you have changed to Terminal mode and established communications
with the module as described earlier in this chapter, and then proceed as follows:
1. Select
Upload hex file from module to host
using the path shown
below:

You are prompted for a filename to upload just as you would be if uploading a
program file.
2. Enter the path, filename, and file extension that you intend to use to store the
uploaded file, as you would with a program file. If the filename you specify
already exists, you will be asked to confirm whether you wish to overwrite it.
3. A dialog box appears in which you must enter the starting and ending
addresses for the hex file upload. Always type in
8000H
for the starting address.
Press
[Tab]
or use the mouse to move the cursor to the Ending Address field.
IMPORTANT
If the file specified already exists in your personal computer,
(always the case if you selected a file from the directory screen), a
confirmation box appears. This box asks you if you want to
overwrite the existing file or abort the upload operation.
