The CIO-DIO192 is a member of a family of digital I/O boards which use the 50-pin connector. Applications can easily be sized from 48 to 192 digital I/O points or more. Software is extensible to multiple points and all the accessories, including screw terminal boards, electro-mechanical relay boards and solid state relay boards interface to the same connector. Regardless of which digital I/O board is used.
I/O Register map
The CIO-DIO192 occupies 32 I/O addresses. The first address, or BASE address, is fixed by the base address switch.
Cabling and Connection
Cabling to the CIO-DIO192 is via standard 50-pin, 0.10" spacing AMP type ribbon cable
connectors. Each cable carries 48 digital I/O lines, +5 V and ground. The CIO-DIO192 has
four connectors.
The CIO-TERM100 screw terminal board provides 100 standard 12-22 AWG screw terminals. The CIO-MINI50 provides 50 such terminals. The SSS-RACK24 mounts 24 solid state relays, and the CIO-ERB24 mounts 24 electro-mechanical relays.
Each connector carries 48 digital I/O lines. One 8255 circuit on pins 1-24 and one on pins 25-48. Each 8255 has 24 I/O lines. The chip is configured as three ports. Two ports, A & B, are 8-bits wide, while port C may be an 8-bit port or two 4-bit ports.Individual ports may be configured as input or output, and are written to or read from as a unit.
Software
Optional software drivers, called UNIV-DRVR, are available for programming in both
DOS, Windows 3.1 & Windows 95. DOS support includes QuickBasic 4.5, Visual
Basic, Turbo C, Visual C++, Microsoft C and Quick C. Windows support includes
Microsoft C, Visual C++, Visual Basic, Borland C, and C++. Labview drivers are also available. (requires UNIV-DRVR)
