To perform a firmware upgrade on your LINDY CPU Switch Multiscreen 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. Upgrade cables may be purchased for LINDY Technology or may be made using the wiring specification given in Appendix A4. You will also need to download the latest version of the LINDY CPU Switch Multiscreen firmware which is available free of charge at www.lindy.com.
Step 5 - Run the upgrade program The latest version of the LINDY CPU Switch Multiscreen firmware is available from the LINDY Technology website at www.lindy.com. The CPU Switch Multiscreen uses the same firmware as the CPU Switch Smart product. The program and data files are supplied as a pair e.g. CPUSS129.EXE CPUSS129.HEX and should be downloaded to the same directory on your PC. Run the file CPUSSxxx.EXE (e.g. CPUSS129.EXE) and follow the on-screen instructions.
without moving switch 7 from the flash upgrade (ON) position. Switch 7 forces the LINDY CPU Switch Multiscreen into flash upgrade mode and prevents the upgraded code from being run. Running faulty or partially upgraded code may have unpredictable results and may damage your LINDY CPU Switch Multiscreen or computing equipment.
3. Using the LINDY CPU Switch Multiscreen This section explains the general operation of the LINDY CPU Switch Multiscreen. We recommend that you read this section before starting to use the product. 3.1 Power on status At power on the LINDY CPU Switch Multiscreen selects computer 1 and displays ’1’.
