1. A software trigger event occurs when you Start the analog input operation the computer issues a write to the module to begin conversions Using software specify the trigger source as a software trigger m External trigger An external digital trigger event occurs when the DT9800 Series module detects a rising edge on the Ext A D Trigger input signal connector The trigger signal is TTL compatible Using software specify the trigger source as an external positive digital TTL trigger Analog Output Channels The DT9802 and DT9804 modules support two DC level analog output channels DACO and DAC1 Within each DAC the digital data is double buffered to prevent spurious outputs then output as an analog signal Both DACs power up to a value of 0 V 10 mV Resetting the module does not clear the values in the DACs The DT9800 Series modules can perform single value analog output operations only Use software to specify the range gain and analog output channel and then output the data from the specified channel You cannot specify a clock source trigger source or buffer Note You cannot perform a single value analog output operation while the A D subsystem is running The settling time for each DAC is 50 us 20 V steps Single value operations stop automatically when finished you cannot stop a single value operation WWW DATATRANSLATION COM US Canapa 800 525 8528 Europe Asia 49 0 7142 9531 0 Digital 1 0 All DT98002. 00 Series module is shipped with the Data Acquisition Omni CD which includes DT Open Layers compliant drivers for Windows XP Windows Vista and Windows 7 ready to run software and a comprehensive user s manual in PDF format Manuals are available in hard copy form for an additional charge DT9801 USB function module with 12 bit 100 kS s analog inputs m DT9802 USB function module with 12 bit 100 kS s analog inputs and two 2 12 bit analog outputs DT9803 USB function module with 16 bit 100 kS s analog inputs m DT9804 USB function module with 16 bit 100 kS s analog inputs and two 2 16 bit analog outputs Accessories User Manual hard copy DIN Rail Kit Kit for mounting modules to walls cabinets or machinery Software The following software is available for purchase separately Measure Foundry Test and measurement application builder for Windows XP Windows Vista and Windows 7 SP1300 CD m quickDAO High performance ready to run application that lets you acquire plot analyze and save data to disk at up to 2 MHz per channel SP8501 CD m LV Link Access the power of Data Translation boards through LabVIEW Free Software Downloads The following software is available for free download from our website DAO Adaptor for MATLAB Access the analyzation and visualization tools of MATLAB using Data Translation boards Copyright 2010 Data Translation Inc All rig

5. Series modules feature 16 digital I O lines These lines are divided into the following 8 bit ports Port A input and Port B output You can also read the status of Port A at rates as high as the maximum speed of the A D by including the digital input lines of Port A as a channel in the analog channel gain list This dynamic digital input feature allows you to time stamp the digital inputs in relation to the analog inputs In this mode all 8 digital input lines of Port A are read as one word The digital outputs have sufficient current capability to drive external solid state relay modules sink 12 mA and source 1 mA If you apply 5 V to the 5 V outputs the digital outputs maintain their previous state if the computer goes down or if the USB cable is unplugged On enumeration the module senses 5 V and does not reset the digital outputs User Counter Timers Two 16 bit counter timers are supported by all DT9800 Series modules The counters are numbered 0 and 1 Each counter accepts a clock input signal and gate input signal and outputs a clock output signal also called a pulse output signal DT9800 Series modules support the following counter timer operation modes Event counting Frequency measurement Rate generation One shot and Repetitive one shot You can cascade two counters internally through software or cascade more than two counters externally on the user connections You can also set the duty cycle frequency and out
