Troubleshooting

This software will NOT run with Windows NT.

1.6.6.1 PC Requirements

The ES9800 software has been verified on a limited group of machine and operating system

combinations as follows.

486DX2-66, Windows 95.

P133, Windows 3.11.

P200, Windows 95.

Note: Operation has not been verified under Windows 98.

There are traps for possible DSKplus firmware download problems. If the user wishes to try again

when a problem is flagged, a System..Initialise function is available from the mainframe menu, if the

‘main panel’ is closed down.

If there are problems communicating with the DSKplus a selftest utility is available. This can be

accessed when the main panel and Tx or Rx panels are closed. From the menu bar, System… HPI

selftest.

Note: The selftest function loads the DSKplus with different firmware. Therefore, to restart the

evaluation software select ‘System... Initialise’. The option ‘System... Open Main Panel’ allows the

main GUIs to be viewed without the hardware being present.

1.6.6.2 Resetting the DSKplus

If the ES9800 windows application is exited abnormally, the DSKplus will not be left in the correct state

for re-starting. In this situation it will be necessary to power-down the DSKplus and power-up again

before attempting to restart the ES9800 windows software. If the power-down is not performed, a

'DSKplus not found !!' message will be displayed.

1.6.6.3 Window Activity and Screensavers

If transmitting random data continuously from the PC it will probably be necessary to disable the

windows screen saver. The processor activity required to invoke the screen saver will prevent data
