1. 2 1 Windows 95 The PCI PDISO16 board is completely plug and play Simply follow the steps shown below to install your PCI PDISO16 hardware 1 Turn your computer off unplug it open it up and insert the PCI PDISO16 into any available PCI slot 2 Close your computer up plug it back in and turn it on 3 Windows 95 will automatically detect the board as it starts up If the board s configuration file is already on the system it will load without user interaction If the configuration file is not detected you will be prompted to insert the disk containing it The required file is on the InstaCal disk you received with your board The appropri ated file will then be automatically loaded and the PCI board will appear in the Device Manager under DAS components 4 Open Control Panel and start Add Remove Programs Insert the InstaCal disk if it s not already in your floppy drive and click install You will then be prompted for some information Follow the instructions and if possi ble accept the defaults If this is your first installation we urge you to accept the defaults It will be easier to assist you in the event of trouble with default settings If you have purchased the Universal Library programmers library the INSTALL EXE program will install all the software required to run the PCI PDISO16 as well as Uni versalLibrary programming language support When you have completed this part of the installation please2. 24 Each input has a software enabled dis abled low pass filter with a time constant of 5mS 200Hz The input filters are described and set by InstaCAL The filter must be used for A C inputs and should be used for almost all D C inputs Unless you have reason to turn off a filter we recommend it be enabled The registers are written to and read from as single 8 bit bytes Each bit controls an output or represents the state of a device or input Registers are read left to right The leftmost bit being the most significant bit Following this format bit 7 of BASE 0 corresponds to relay 7 and bit 0 to relay 0 Chapter 3 PROGRAMMING 3 1 Address Register Map To construct a control word use the following table BIT No 7 6 5 4 HEX Value 380 40 20 10 DECIMAL 128 64 32 16 The PCI PDISO16 is easy to program two 8 bit registers are written to control the 16 relays two 8 bit registers are read to monitor the 16 digital inputs and two 8 bit regis ters are written to enable disable the low pass filters on the inputs The board is con figured as two independent 8 bit I O ports Each of the 8 bit ports uses distinct I O addresses and connectors For descriptive purposes we will call them I O Port A and T O Port B The overall address register map is shown below group 00 W A RIN NN O To assemble a control byte RELAY HEX ON 1 WEIGHT DECIMAL ON 1 WEIGHT OP7 80 1 80 128 1 128 PORT A see diagram for connector location
