7. Locate and select the file 351-0084-<VER>.HEX (the firmware version may vary). To
obtain the latest version of the Control Unit firmware, visit the Electroline Web site or
contact the technical support department. Once you have located the file, click
OK
.
Warning:
The Control Unit’s current setup will be overwritten with default values as soon as the
upgrade process begins. It is therefore important to note the unit’s parameters before
upgrading the firmware (
info
command). If you have not done so already, cancel the
upgrade and print out the Control Unit’s current setup now (see section 5.4).
8. When the screen appears asking if you would like to perform a backup of the Control
Unit’s firmware, click
NO
. The Initialization and Reading 351-0084-x.xx.hex progress
bars will appear. Note that while you are upgrading the firmware (reprogramming mode)
the Control Unit, the
STATUS
LED will flash regularly; the
RX
/
TX 3
LED will flicker at
each data transfer. Following the initialization and reading, the new program is sent to
the Control Unit.
9. At the end of the upgrade operation, a checksum appears. Make sure that this value
corresponds to the value indicated in the file CHECKSUM.TXT that accompanies the
current version of the .HEX upgrade file. Visit the Electroline Web site or contact
technical support to obtain the checksum file.
10. Exit the Control Unit upgrade program and start HyperTerminal or another
communications program so that you can log on to the Control Unit.
11. Verify the checksum generated by the Control Unit by using the
prog?
command
(see section 5.5.2).
12. Since the firmware upgrade resets the Control Unit’s setup to the default values, you
must restore the Control Unit’s setup by defining the following operating parameters.
•
date
•
time
•
password
•
COM ports
•
RF watchdog
•
Control Unit ID
•
redundancy failure notification setting
•
carrier tag
You may use the information obtained from the
info
command or use the printed sheet
that was shipped with your Control Unit as a guide during the setup procedure. See
Chapter 3 for setup instructions.
