• PCI-EXT64 PCI Extender Card with exchangable upper slot for 64 Bit and 32 Bit slots

This high quality ISA extender card was developed to allow the testing of ISA slot cards. Hereby, it is possible to remove the tested ISA board while the computer is running. The upper ISA slot is easily exchangeable, separately orderable and reduces costs in large scale production and testing. The ISA-EXT allows an easy check of prototype boards and other ISA boards.

How to use the board ?
Before you remove the ISA slot card, switch the power on the ISA extender card off. This shuts down the tested board power lines and signals from the pc bus. Remove the board and insert a different one. Switch the power on again. The board gets a reset and all lines power up in a safe way.

General description
To reduce the time for comfortable testing of PC cards we decided to develop the ISA Extender card. A master switch on one side of the extender card switches all ISA-Bus signals and voltages. This is required to allow hotplugging of the tested ISA cards. This method allows the inserting and removing of ISA cards without rebooting and destroying the PC.All operating voltages are protected by easy exchangable fuses. The ISA-Extender can be configured with a DIP switch. With the DIP switch you can select which type of signals will be passed through to the upper slot of the ISA Extender. This feature will help you to find errors in cards that contain short circuited data or address signals. All operating voltages are available at the 9-pin D-Sub connector. The connector allows the operation of external devices that need a additional power supply. All standard ISA slot voltages are available at this connector. To reset the ISA board under test condition simply press the reset button on the ISA-Extender board. This acitvates the ISA slot reset signal and resets the hardware on you ISA card. Secondly the reset signal is generated by powering the PC off an on.

Highlights
The ISA extender card allows an inserting and removing of ISA cards while the computer is switched on (hot swapping). Since the lifetime of any electrical connector is limited, we made the upper ISA slot seperately deliverable and exchangeable. The costs in large scale production and testing are reduced dramatically, due to the fact that only the upper ISA slot, when worn out, needs to be replaced and not the whole ISA Extender. This is the reason why many companies are using our ISA extender card in the mass production. If the upper ISA bus connector is worn out, just replace it with a new one.
