Quick-Start.pdf. Configuring the CIO-DAC08 The CIO-DAC08 has one base address switch, one bank of gain switches for each analog output channel, a simultaneous update jumper for each DAC pair, a "power-up state" selection jumper, and one wait state jumper which you must set before installing the board in your computer. The InstaCal calibration and test program included with the CIO-DAC08 will show you how to set the switches. - Page 10 Serial port The CIO-DAC08 Base switch can be set for an address in the range of 000-3E0, so it should not be hard to find a free address area for your CIO-DAC08. If you are not using IBM prototyping cards, or some other board which occupies these addresses, then 300-31F HEX are free to use.

Page 11: Wait State Jumper
Wait state jumper The CIO-DAC08 board has a wait state jumper which you can set to enable an on-board wait state generator. A wait state is an extra delay injected into the processor's clock via the bus. This delay slows down the processor when the processor addresses the CIO-DAC08 board so that signals from slow devices (chips) will be valid. -

CIO-DAC08 User's Guide Installing the CIO-DAC08 The analog outputs of the CIO-DAC08 are two-wire hook-ups. Always use low-level ground (LLGND) as the ground reference for all analog hook-ups. Cabling The red stripe identifies pin # 1 Figure 7. C37FF-x cable Figure 8. -
Page 15: Programming And Developing Applications
You should use the Universal Library or one of the packaged application programs mentioned above to control your board. Only experienced programmers should try register-level programming. If you need to program at the register level in your application, refer to the Register Map for the CIO-DAC08 and CIO-DAC16. This document is available on our website at www.mccdaq.com/registermaps/RegMapCIO-... -

As the load resistance decreases, the output load increases. The OP07 responds by producing a lower output voltage. If your CIO-DAC08 will not produce the output voltage specified by the code & range combination, it is a good idea to check the load with an ohm meter. -
