DESCRIPTIONNAMEDESCRIPTIONNAME

2.2.3 WAIT STATE

A wait state can be enabled on the CIO-DAS800 by selecting WAIT STATE ON at the jumper provided

on the board. Enabling the wait state causes the personal computer's bus transfer rate to slow down

whenever the CIO-DAS800 is written to or read from. The wait state jumper is provided in case you one

day own a personal computer with an I/O bus transfer rate which is too fast for the CIO-DAS800. If your

board fails sporadically in random ways, try setting the wait state ON.

2.2.4 INSTALLING THE CIO-DAS800 IN THE COMPUTER

1. Turn the power off.

2. Remove the cover of your computer. Please be careful not to dislodge any of the cables installed

on the boards in your computer as you slide the cover off.

3. Locate an empty expansion slot in your computer.

4. Push the board firmly down into the expansion bus connector. If it is not seated fully it may fail

to work and could short circuit the PC bus power onto a PC bus signal. This could damage the

motherboard in your PC as well as the board.

5. Power up your computer and run the InstaCal test to verify your hardware installation.
