DESCRIPTION NAME DESCRIPTION NAME
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.
