Analog output is provided by two 12-bit multiplying D/A converters. This type of converter accepts a

reference voltage and provides an output proportional to that. The proportion is controlled by the D/A

output code (0 to 4095). Each bit represents 1/4096 of full scale.

A precision −5V and −10V reference provide onboard D/A ranges of 0 to 5V, 0 to 10V, +/-5V, +/-10V.

Other ranges between 0V and 10V are available if you provide a precision voltage reference at pin 10

(D/A0) or 26 (D/A1) of the main connector.

When the DAC1 reference is supplied onboard, pin 26 of the 37-pin connector is unused and can be

employed as a SSH (simultaneous sample & hold) trigger for use with the CIO-SSH16. To do so, place

the jumper between the two pins “SH” (Figure 2-5).
