1. MOV DX 387H OUT DX AL Appendix B 120 APPENDIX C ANALOG INPUT ANALOG INPUT The analog input circuitry includes the LTC1290 I C from the Linear Technology corporation Ph 408 432 1900 The LTC1290 contains a serial I O successive approximation A D converter The chip s 8 channe input multiplexer can be configured for either single ended or differential inputs or combinations thereof For input protection we have added current limiting resistors and a diode clamp array to the circuit In addition you can install capacitors in the circuit for implementing a low pass filter to reduce noise Differential Mode Option The use of the differential input mode is useful when the signal source transmits both a plus and a minus signal If you are reading signals generated from strain gauges pressure transduc ers or any device that generates a differential output you can use the differential mode Input Filter Capacitors It is very important that the signals especially the minus signal remain as stable as possible when using the differential mode Ifa signal is noisy or varies in level the resulting conversion data will be in error It is possible to add filtering capacitors that help reduce the effect of any extraneous noise on the signal A properly sized filter capacitor will cut off high frequencies that can cause inaccurate readings The filter capacitor should be a monolithic ceramic type

4. MAJOR FEATURES ROM DOS Operating System ROM DOS is a MS DOS version 6 22 compatible operating system Since it is stored in ROM it is always present on power up During run time it requires only about 20K of RAM space Solid State Disk Options The 6012 has sockets for two solid state disks The boot disk SSD1 accepts one or two 256K flash EPROMs The data disk SSD2 accepts a 128K or 512K static RAM The SSD1 socket normally contains the program to be executed on power up The program is automatically loaded into DOS memory and executed A program residing in memory can be transferred into the flash using the on card programmer and supplied soft ware Only flash EPROMs may be programmed These devices are erased automatically during the programming process Multiple programs may be stored as long as the total size does not exceed 512K The SSD2 socket supports only a 128K or 512K static RAM which is used for data storage To retain data during power outages the DS 1216DM calendar clock that plugs into this socket will also battery back the RAM The solid state disks reside in memory that is separate from the 640K of DOS memory Software drivers are provided Also if your application requires additional program and data storage capabili ties you can add Micro PC 5805 Solid State Disk Cards to your system Overview 5 Programmable Analog Inputs There are eight channels that have software programmable modes and input
