5. Upgrading the LINDY CPU Switch's firmware
The LINDY CPU Switch Dual MP uses flash memory technology which enables the
firmware code to be upgraded by the user. New keyboards, mice operating systems
and drivers are being launched all the time. From time to time the LINDY CPU
Switch's firmware will be updated to provide support for these new devices. You can
take advantage of these upgrades free of charge during the warranty period.
Upgrades are performed by connecting a PC's serial port to the LINDY CPU Switch's
serial port and running an upgrade program on the PC. This upgrade program
downloads the new firmware to the LINDY CPU Switch Dual MP and checks that the
data has been programmed correctly.
You can check the version of the firmware that is currently loaded into your LINDY
CPU Switch using the on-screen menu. To do this activate the on-screen menu using
the keyboard hotkeys (see section 4.10) and then press F1. The version number of
the current firmware will then be displayed at the bottom of the Configuration Menu.
To perform a firmware upgrade on your LINDY CPU Switch Dual MP you will need a
suitable serial upgrade cable and an IBM PC compatible computer with an RS232
serial port and an operating system that supports DOS. Suitable upgrade cables with
9-pin serial connectors are provided with the LINDY CPU Switch Dual MP. If you
have lost your cable then you will need to buy a cable with a 9-way D-type male
connector on one end and a 9-way D-type female connector on the other end with all
9 lines connected "straight through" (i.e. pin 1 to pin 1, pin 2 to pin 2, pin 3 to pin 3
etc.). These are standard serial extension cables.
You will also need to obtain the latest version of the LINDY CPU Switch Dual MP
firmware which is available by request from LINDY .
Note: The normal flash upgrade process does not clear the computer names, user
names, security passwords or other configuration settings.
