1 INTRODUCTION The PCI-DIO96 is a 96-bit line digital I/O board. The board provides the 96 bits in four 24-bit groups. Each group provides an 8-bit port A and port B, as well as an 8-bit port C that can be split into independent 4-bit port C-HI and a 4-bit port C-LO. See Figure 1-1 below. On power up and reset, all I/O bits are set to input mode. If you are using the board to control items that must be OFF on reset, you will need to install pull-down resistors. Provisions have been made on the

2 INSTALLATION The PCI-DIO96 boards are completely plug-and-play. There are no switches or jumpers on the board. All board addresses are set by your computer’s plug-and-play software. InstaCal is the installation, calibration and test software supplied with your data acquisition / IO hardware. Refer to the Extended Software Installation Manual to install InstaCal. If you need it, there is some on-line help in the InstaCal program. Owners of the Universal Library should read the manual and exami

3.3 SIGNAL CONNECTION CONSIDERATIONS All the digital inputs on the PCI-DIO96 are 8255 CMOS TTL. The PCI-DIO96 output signals are 8255 CMOS. OMEGA Engineering Inc. offers a wide variety of digital signal conditioning products that provide an ideal interface between high voltage and/or high current signals and the PCI-DIO96. If you need control or monitor non-TTL level signals with your board, please refer to our catalog or our web site for the following products: CIO-ERB series, electromechan

3.4 CIO-ERB24 & SSR-RACK24 CONNECTIONS PCI-DIO96 boards provide digital I/O in two major groups of 48 bits each (96 total, but each side of the C100FF-xx cable provides 48 bits). However, many popular relay and SSR boards provide only 24-bits of I/O. The CIO-ERB24 and SSR-RACK24 each implements a connector scheme where all 96 bits of the PCI-DIO96 board may be used to control relays and/or SSRs. This configuration is shown in Figure 3-4 below. The 24-bits of digital I/O on PCI-DIO96 connector pi

4 SOFTWARE We highly recommend that users take advantage of our Universal Library package's easy-to-use programming interfaces. However, if you are an experienced programmer, and wish to read and write directly to the board, we have provided a detailed register map in the next chapter. 4.1 UNIVERSAL LIBRARY The Universal Library provides complete access to the PCI-DIO96 functions from a range of programming languages. If you are planning to write programs, or would like to run the example progra
