Introducing the CIO-DDA06/Jr/16
Overview: CIO-DDA06/Jr/16 features
The CIO-DDA06/JR/16 board combines up to six channels of analog output with 24 digital input/output
channels. The analog outputs are from AD660 DACs with each output buffered by an OP27.
Two analog output channels (AD660s) are installed in the board. Additional channels can be purchased in
pairs. (Additional AD660s are easily-installed plug-in chips.)
The analog outputs can be set for simultaneous update. Selecting XFER on the XFER/ UPDATE jumper causes
all analog data to be transferred to the outputs simultaneously. The simultaneous update option is a useful
feature for maintaining a known voltage at power-up. The power-up output voltage is zero volts, but the data in
the registers is unknown. Using the simultaneous update feature, the registers may be loaded with known data
(normally mid-scale or 8000h) and then all outputs updated to that value simultaneously.
The digital I/O lines are a direct interface to high-drive output and input latches. The digital control registers
emulate an 82C55 in mode 0 (simple I/O).
