RANGE

The PC104-DAC06 BASE switch may be set for address in the range of 000-3F0 so it

should not be hard to find a free address area for your PC104-DAC06. Once again, if

you are not using IBM prototype cards or some other board which occupies these

addresses, then 300-31Fh are free to use. Address not specifically listed, such as

390-39Fh, are free.

3.2 SIMULTANEOUS UPDATE JUMPER

The analog outputs can be jumpered so that new output data is held until two, four, or

six DACs have been loaded with new digital data. Then, as a group, those that are

jumpered for simultaneous outputs will have that new data sent to the voltage outputs.

Simultaneous update occurs whenever any addresses BASE + 0 through BASE + 11

are read.

The analog output chips are dual DACs. A single jumper sets both DACs on a single

chip to be either simultaneous TRANSFER or individual UPDATE.
