5.4 Upgrading the Control Unit’s firmware
This section explains how to upgrade the Control Unit’s firmware, which is its internal
operating code. Normally, a firmware upgrade is only required if it has been recommended
by Electroline’s technical support staff.
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.
Once you have finished the firmware upgrade, you will have to set up the Control Unit’s
parameters. Your Control Unit was shipped with a printed sheet showing the parameters that
were programmed in the factory. If you would like the Control Unit to have the same settings
after the firmware upgrade, you may use this sheet to guide you in the setup procedure. You
can also display the Control Unit’s setup with the
info
command and then print the screen.
For setup instructions, see Chapter 3.
Before beginning the upgrade, make sure you have the following:
• upgrade program for the Control Unit IV (EAS Control Unit IV Upgrade), installed on a
PC (visit the Electroline Web site or contact the technical support department for the
most recent version)
• current version of the firmware file and the checksum file (visit the Electroline Web site
or contact the technical support department)
• communication program such as HyperTerminal
• a printout of the Control Unit’s current parameters
5.4.1 Installing the upgrade program
1. Insert the CD with the Electroline Control Unit upgrade program (CU4UP) in your
computer’s CD-ROM drive. The CU4UP startup program menu automatically appears
once the CD is loaded. Note that the upgrade program can also be downloaded from the
Electroline Web site if the CD-ROM is not available.
