The National Instruments SB Series DAQ boards are packaged with NI DAQ software for Sun which comes with a language interface for ANSI C National Instruments Corporation 1 3 SCXI 1162HV User Manual Introduction Chapter 1 Register Level Programming The final option for programming any National Instruments DAQ hardware is to write register level software Writing register level programming software can be very time consuming and inefficient and is not recommended for most users The only users who should consider writing register level software should meet at least one of the following criteria e National Instruments does not support your operating system or programming language You are an experienced register level programmer who is more comfortable writing your own register level software Even if you are an experienced register level programmer always consider using NI DAQ LabVIEW or LabWindows to program your National Instruments DAQ hardware Using the NI DAQ LabVIEW or LabWindows software is easier than and as flexible as register level programming and can save you weeks of development time The SCXI 1162HV User Manual and your software manuals contain complete instructions for programming your SCXI 1162HV with NI DAQ LabVIEW or LabWindows If you are using NI DAQ LabVIEW or LabWindows to control your board you should not need the register level programmer manual The SCXI 1162HV Register Level Programmer Man2. mA Common mode isolation bank to bank and bank to ground WOrking ned RUPEE eret 450 Vrms max Common mode rejection essere 500 V us typ Maximum speed Propagation delay parallel mode Av Rm 1 5 ms Se al data Tate 21 oae oer ere 1 000 words s Physical DirmiensionSzu cote ede ete tr tas retains 1 2 by 6 8 in by 8 0 in 33 78 by 9 91 cm I O confector eee ree ee tdi 50 pin male ribbon cable rear connector 48 pin DIN C male front connector SCXI 1326 screw terminal adapter available Environment Operating temperature sese 0 to 50 C Storage temperature sssessseeeeeeeene en 40 to 125 C Relative humidity sees 596 to 9096 noncondensing 1 Transfer rate depends on the computer and software These tests were made using a 50 MHz 80486 computer running NI DAQ software National Instruments Corporation A 1 SCXI 1162HV User Manual Appendix B Customer Communication For your convenience this appendix contains forms to help you gather the information necessary to help us solve technical problems you might have as well as a form you can use to comment on the product documentation Filling out a copy of the Technical Support Form before contacting National Instruments helps us help you better and faster National Instruments provides comprehensive technical assistance around the world In the U S and Canada applicatio

Hz signal with a voltage of at least 20 Vrms returns a constant logic high level For 1 KHz and higher frequency signals a 2 Vrms signal returns a constant logic high level The current limiting circuitry limits the current to 1 5 mA for input voltages up to 240 Vrms for a sinusoidal signal Signal Isolation The GND and inputs of each bank are isolated from the GND and inputs of any other bank In addition all signals are isolated from the chassis earth ground and the internal circuitry of the module These barriers provide isolation for voltages up to 450 VAC or VDC and protect the user and the SCXI system There is no isolation between signals of the same bank You must not exceed the voltage limits of the inputs referenced to their respective GND signals Signal Connection Example In Figure 3 2 one channel of the SCXI 1162HV is being used to sense that a load is being powered The load is connected to a power supply by means of a switch This power supply can be AC or DC and can be any voltage within the SCXI 1162HV range Common supplies may include 5 VDC 48 VDC or 120 VAC 60 Hz When the switch is open no current flows through the load and no voltage is applied to the load or to the SCXI 1162HV input The digital logic of the SCXI 1162HV then registers a logic low or 0 for the channel When the switch is closed the power supply voltage is applied across both the load and the input and the SCXI 1162HV registers a logic high or 1 for t
