Updating BIOS Software
Occasionally, BIOS software updates are available to enhance the operation of the controller.
These updates are available through the Service Deptartment or for download from the
internet. To find out what the current BIOS software version is, call the Service Department
for details.
You can update the software with a laptop computer and an RS-232 serial connection through
the COM1 serial port. As shown in the electrical diagrams and the electrical diagram on the
following page, connect a serial cable as shown. Follow the installation program instructions
supplied with the software update. The installation program automatically updates the BIOS.
