3.2 SIMULTANEOUS TRANSFER JUMPER - CIO-DAS08/JR/16-AO Only
The analog outputs can be jumpered so that new output data are held until both DAC channels have been loaded with new digital data.
Then, the new data updates the voltage outputs occurs when any addresses are read.
Figure 3-2. Simultaneous XFER/Individual UPDATE Jumper
A single jumper sets the DACs for either simultaneous transfer (XFER) or individual UPDATEs (Figure 3-2).
3.3 INSTALLING THE BOARD 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 CIO-DAS08/JR/16-AO.
