Model 5600ACO2 Automatic Changeover Unit
4.2. UPGRADING THE FIRMWARE
4.2.1. Overview
The firmware in the 5600ACO2 is contained on a FLASH EPROM. From time to time firmware updates
will be provided to add additional features to the unit.
You will need the following equipment in order to update the Firmware:
• PC with available communications port. The communication speed is 57600 baud, therefore a 486
PC or better with a 16550 UART based communications port is recommended.
• “Straight-thru” serial extension cable (DB9 female to DB9 male) or (DB25 female to DB9 male).
• Terminal program that is capable of Xmodem file transfer protocol. (such as HyperTerminal)
• New firmware supplied by Evertz.
4.2.2. Terminal Program Setup
1. Connect the serial cable to the COM DB9 connector on the rear panel.
2. Connect the 9 pin connector on the end of the serial update cable to the PCs’ RS-232
communications port.
3. Start the terminal program.
4. Configure the port settings of the terminal program as follows:
Baud
57600

5. Power up the 5600ACO2 unit.
4.2.3. Initiating Firmware Upgrade Mode From The Terminal Program
7. Power up the 5600ACO2. After the unit powers up, a banner with the boot code version information
should appear in the terminal window. The cursor to the right of the word “BOOT>” should be
spinning.

8. The following is a list of possible reasons for failed communications:
• Defective Serial Upgrade cable.
• Wrong communications port selected in the terminal program.
• Improper port settings in the terminal program. (Refer to step 4 for settings). Note that
HyperTerminal will not change port settings while connected. Click on HyperTerminal’s
“Disconnect” Button then click the “Reconnect” button to activate changes to the port settings.
