5. Upgrading the LINDY CPU Switch's firmware
The LINDY CPU Switch Dual Junior 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 Junior 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 Junior 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
Junior. 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 Junior
firmware which is available by request from www.LINDY.com. Please ensure that
you have your product serial number and model number at hand when requesting
an upgrade.
Note: The normal flash upgrade process does not clear the computer names, user
names, security passwords or other configuration settings.
