Measurement Computing CIO-DAS08-AOH - Manual (Page 8)

3.4 WAIT STATE
A wait state may be enabled on the CIO-DAS08-AOx 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-DAS08-AOx 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-DAS08-AOx. If your board were to fail sporadically in random ways,
you could try using it with the wait state ON.

3.5 D/A RANGE SWITCH
The analog output voltage range is selectable. A set of DIP switches, one set of six per channel, allow you to choose a range
for each channel (Figure 3-5 and Table 3-3). .
