1. Analog output ranges are switch selectable for a Bipolar or Unipolar range Bipolar ranges are 10 V 5 V and 2 5 V Unipolar ranges are 0 to 10 V 0 to 5 V and 0 to 2 5 V The analog outputs are controlled by writing a digital control word as two bytes to the DAC s control register The control register is double buffered so the DAC s output is not updated until the second byte the high byte is written Each analog output pair is jumper selectable for either individual or simultaneous update When a DAC pair is set for simultaneous update writing new digital values to the DAC s control register does not update the DAC s voltage output Update of the output occurs only after a READ from the board s addresses The board also features a wait state generator that you enable with an on board jumper Software features For information on the features of nstaCal and the other software included with your CIO DACOS refer to the Quick Start Guide that shipped with your device The Quick Start Guide is also available in PDF at www mecdaq com PDFmanuals DAQ Software Quick Start pdf Check www mccdaq com download htm for the latest software version Chapter 2 Installing the CIO DAC08 What comes with your CIO DAC08 shipment The following items are shipped with the CIO DACOS Hardware CIO DACOS Additional documentation In addition to this hardware user s guide you should also receive the Quick2. 2E8 2EF Serial Port 060 064 8742 Controller AT 2F8 2FF Serial Port 070 071 CMOS RAM amp NMI mask AT 300 30F Prototype card 080 08F DMA page registers 310 31F Prototype card 0A0 0A1 8259 PIC 2 AT 320 32F Hard disk XT 0A0 0AF NMI mask XT 378 37F Parallel printer 0OC0 0DF 8237 2 AT 380 38F SDLC OF0 0FF 80287 numeric CO P AT 3A0 3AF SDLC 1FO 1FF Hard disk AT 3B0 3BB MDA 200 20F Game control 3BC 3BB Parallel printer 210 21F Expansion unit XT 3C0 3CF EGA 238 23B Bus mouse 3D0 3DF CGA 23C 23F ALT bus mouse 3E8 3EF Serial port 270 27F Parallel printer 3F0 3F7 Floppy disk 2B0 2BF EGA 3F8 3FF Serial port The CIO DACOS Base switch can be set for an address in the range of 000 3E0 so it should not be hard to find a free address area for your CIO DAC08 If you are not using IBM prototyping cards or some other board which occupies these addresses then 300 31F HEX are free to use Addresses not specifically listed such as 390 39F are free 10 CIO DAC08 User s Guide Installing the CIO DACO08 Wait state jumper The CIO DACOS board has a wait state jumper which you can set to enable an on board wait state generator A wait state is an extra delay injected into the processor s clock via the bus This delay slows down the processor when the processor addresses the CIO DACOS board so that signals from slow devices chips will be valid This jumper is shown in Figure 2 configured for OFF wait stat
