CONTROLLER FIRMWARE UPGRADE PROCEDURE
You will need to use a Windows based computer to conduct these changes. On the back of the
controller, disconnect the KEYPAD RS-232 cable. Connect this port to the computer you will
use to upgrade the protocol using an RS-232 cable.
***Before conducting protocol input, you should prepare your computer:
1.
Ensure the controller is powered off.
2.
After connecting the computer to the KEYPAD port by RS-232, turn the PROGRAM
switch so that it is set to the right side.
3.
Select the Com Port you are using to conduct the update by opening Windows Device
Manager. Press Start -> Control Panel -> System and Security. In the System and
Security submenu you will see Device Manager. Check that the RS-232 port is active. If
not, activate the port. Exit and open device manager again to ensure the changes were
committed.
4.
Power the controller ON and run STMicroelectronics flash loader to conduct the
upgrade. In the Flash Loader, select the connected port number in the "Port Name" drop
down menu. Press Next.
5.
If a connection between the controller and computer is made, the light will appear green
and you may continue the update process by pressing Next. If a connection is not
available, the light will appear red. In this case, check the Com Port in Windows Device
Manager and ensure it is active. Press Next in the following window.
6.
Select the file to load, and ensure that Global Erase and Optimize (Remove some FFs)
are selected. Press Next to continue.
7.
A window will appear requesting the location of the .hex file. Find the relative file and
select Open. The upgrade will commence. Do not power off or disconnect the computer
and controller, or use any other programs while the upgrade is in process.
8.
When the upgrade completes, press Close and power off the controller. Turn the
PROGRAM switch to the left to deactivate programming mode.
9.
Disconnect the computer used to update the firmware and reconnect the podium control
pad's RS-232 cable to the KEYPAD port. Turn off the computer's Com Port.
10. Power on the controller. The controller should emit a beep sound, signalling the upgrade
was successful.
