0 V ±10 mV. Resetting the module does not clear the values in the analog output channels. Output Ranges and Gains All DT9850 Series modules support an output range of ±10 V (default) or 0 to 10 V. Specify the range for the entire subsystem using software; you cannot specify unique ranges for individual channels.
0000 to the output corresponds to 0 mA; writing a code of FFFF to the output corresponds to 20 mA. Output Resolution All DT9850 Series modules support an analog output resolution of 16 bits. The resolution cannot be programmed in software. Output Clock (Continuous Mode Only)
Principles of Operation Operation Modes You can perform the following analog output operations on DT9850 Series modules: • Update one analog output channel with a single value • Simultaneously update analog output channels on one module with a single value •...
Page 56
In this scheme, you must configure the trigger source for one module (called the master module) as Software. Configure the trigger source for the other DT9850 Series modules (called slave modules) as an External Positive TTL trigger. In this configuration, the DAC_Sync signal is configured as an output on the master module and as an input on the slave modules.
Continuously Updating Analog Output Channels on One Module with a Waveform If you want to write a waveform to one or more analog output channels on one DT9850 Series module, use software to perform a continuously paced analog output operation. This is also known as streaming analog output data.
• LSB is the least significant bit. • FSR is the full-scale range. For the DT9850 Series, the full-scale analog output range is 10 for the unipolar range of 0 to 10 V, or 20 for the bipolar range of ±10 V.
Page 59
Principles of Operation For example, assume that you are using a DT9853 module with a bipolar output range of ±10 V. The minus full-scale value is −10 V. If you want to output a voltage of 4.7 V, determine the code value as follows: LSB = = 0.000305 V 65536...
Interrupts The DT9850 Series modules can generate an interrupt when digital input line 0 to 6 of the digital input port changes state. This feature is useful when you want to monitor critical signals or when you want to signal the host computer to transfer data to or from the module.
Principles of Operation Operation Modes DT9850 Series modules support the following digital I/O operation modes: • Single-value operations – Use software to specify the DIN or DOUT subsystem, the resolution (8), and the gain (1) of the subsystem. Data is then read from or written to the appropriate digital I/O lines.
Chapter 5 Counter/Timer Features DT9850 Series modules provide one 32-bit counter/timer (counter/timer subsystem 0) that accepts a counter input signal with a frequency of up to 1 MHz. The module counts the number of rising edges that occur on the counter input signal. You can count a maximum of 4,294,967,296 events before the counter rolls over to 0 and starts counting again.
The tables in this chapter summarize the features available for use with the DT-Open Layers for .NET Class Library and the DT9850 Series module. The DT-Open Layers for .NET Class Library provides properties that return support information for specified subsystem capabilities.
