Appendix Figure 13A shows how to connect a floating signal source to the STP connection box using differential inputs. (A floating signal source is a voltage source that has no connection with earth ground.) Note: For floating signal sources, we recommend that you provide a bias return path for the differential channels by using the Open Layers Control Panel applet to enable 10 kΩ...
Page 53
Note that since they measure the difference between the signals at the high (+) and low (− ) inputs, differential connections usually cancel any common-mode voltages, leaving only the signal. However, if you are using a grounded signal source and ground loop problems arise, connect the differential signals as shown as Figure 14.
Appendix Connecting Current Loop Inputs Note: You cannot connect a current loop input to the BNC connection box using the BNC connectors. Figure 15 shows how to connect a current loop input (channel 0, in this case) to an STP connection box.

Frequency Measurement One way to measure frequency is to connect a pulse of a known duration (such as a one-shot output of counter/timer 1) to the Counter 0 Gate input. Figure 23 shows how to connect counter/timer signals to the STP connection box. In this case, the frequency of the Counter 0 clock input is the number of counts divided by the period of the Counter 0 Gate input signal.
Appendix Edge-to-Edge Measurement Figure 25 shows how to connect counter/timer signals to the STP connection box to perform an edge-to-edge measurement operation using two signal sources. The counter measures the number of counts between the start edge (in this case, a rising edge on the Counter 0 Clock signal) and the stop edge (in this case, a falling edge on the Counter 0 Gate signal).

Principles of Operation The DT9834 Series modules can acquire data from a single analog input channel or from a group of analog input channels. The following subsections describe how to specify the channels. Specifying a Single Analog Input Channel The simplest way to acquire data from a single analog input channel is to specify the channel for a single-value analog input operation using software;...
Specifying the Digital Input Port in the Analog Input Channel List The DT9834 Series modules allow you to read the digital input port (all 16 digital input lines) using the analog input channel list. This feature is particularly useful when you want to correlate the timing of analog and digital events.

Chapter 5 Performing Dynamic Digital Output Operations Note: This feature is accessible using the DataAcq SDK. It is not supported in the DT-Open Layers for .NET Class Library. Using software, you can enable a synchronous dynamic digital output operation for the analog input subsystem.
Principles of Operation Input Ranges and Gains Table 9 lists the supported gains and effective bipolar input ranges for each. Table 9: Effective Input Range Gain Input Range ±10 V ±5 V ±2.5 V ±1.25 V Using software, specify a range of − 10 V to +10 V. Note that this is the range for the entire analog input subsystem, not the range per channel.
Chapter 5 Input Sample Clock Sources DT9834 Series modules allow you to use one of the following clock sources to pace analog input operations: • Internal A/D clock – Using software, specify the clock source as internal and the clock frequency at which to pace the operation.
Principles of Operation In an abrupt stop, the module stops acquiring samples immediately; the acquired data is not transferred to host memory, and any subsequent triggers are ignored. Continuous Scan Mode Use continuous scan mode if you want to accurately control the period between conversions of individual channels in a scan.
You can acquire up to 262,144 samples per trigger (256 times per trigger x 1024-location channel list). DT9834 Series modules support two triggered scan modes: software retriggered and externally retriggered. These modes are described in the following subsections.
• External digital (TTL) trigger – An external digital (TTL) trigger event occurs when the DT9834 Series module detects a transition (rising-edge or falling-edge) on the External ADC Trigger input signal connected to the module. Using software, specify the trigger source as an external, positive digital (TTL) trigger for a rising-edge digital trigger, or an external, negative digital (TTL) trigger for a falling-edge digital trigger.
0 and 255, where 0 equals 0 V and 255 equals +10 V. Data Format and Transfer DT9834 Series modules use offset binary data encoding, such as 000 (for 12-bit modules) or 0000 (for 16-bit modules) to represent negative full-scale, and FFFh (for 12-bit modules) or FFFFh (for 16-bit modules) to represent positive full-scale.
Output Resolution Table 10 lists the output resolution of the DT9834 Series modules that support analog output operations. The resolution is fixed at either 12 bits or 16 bits, depending on the module you are using; you cannot specify the resolution in software.
0 V ±10 mV. Unplugging the module resets the DACs to 0 V. The DT9834 Series modules can output data from a single DAC or sequentially from one or more DACs and/or the digital output port. The following subsections describe how to specify the DACs/port.
255 corresponds to a 10 V. Output Triggers A trigger is an event that occurs based on a specified set of conditions. The DT9834 Series modules support the following output trigger sources: • Software trigger – A software trigger event occurs when you start the analog output operation.
• Continuous analog output operations take full advantage of the capabilities of the DT9834 Series modules. In this mode, you can specify an output channel list, clock source, trigger source, buffer, and buffer wrap mode. Two continuous analog output modes are supported: continuously paced and waveform generation mode.
Principles of Operation We recommend that you allocate a minimum of two buffers for a continuously paced analog output operation. Data is written from multiple output buffers continuously; when no more buffers of data are available, the operation stops. The data is gap-free. To stop a continuously paced analog output operation, you can stop queuing buffers for the analog output system, letting the module stop when it runs out of data, or you can perform either an orderly stop or an abrupt stop using software.
Error Conditions The DT9834 Series modules can report an error if one of the following conditions occurs: • Output FIFO Underflow – The output channel list data is not being sent from the host fast enough.
A digital line is high if its value is 1; a digital line is low if its value is 0. On power up or reset, a low value (0) is output from each of the digital output lines. The DT9834 Series modules allow you to program the first eight digital input lines to perform interrupt-on-change operations. Refer to page 96 for more information.
Page 96
Chapter 5 − Digital output – For digital output operations, enter the digital output port (all 16 digital output lines) as channel 4 in the output channel list; refer to page 90 for more information. The output clock (internal or external) paces the update of the digital output port (as well as the update of the analog output channels);...
99 C/T Channels The DT9834 Series modules provide five 32-bit counter/timers. The counters are numbered 0, 1, 2, 3, and 4. Each counter accepts a clock input signal and gate input signal and outputs a pulse (pulse output signal), as shown in...
The frequency of the external C/T clock can range from .004 Hz to 9 MHz. Connect the external clock to the Counter n Clock input signal on the DT9834 Series module. Counter/timer operations start on the rising edge of the clock input signal.
Specify the gate type in software. Pulse Output Types and Duty Cycles The DT9834 Series modules can output the following types of pulses from each counter/timer: • High-to-low transitions – The low portion of the total pulse output period is the active portion of the counter/timer clock output signal.
Chapter 5 • One-shot • Repetitive one-shot Note: The active polarity for each counter/timer operation mode is software-selectable. The following subsections describe these modes in more detail. Event Counting Use event counting mode if you want to count the number of rising edges that occur on the Counter n Clock input when the Counter n Gate signal is active (low-level or high-level).
Principles of Operation Frequency Measurement Use frequency measurement mode if you want to measure the number of rising edges that occur on the Counter n Clock input over a specified duration. You can connect a pulse of a known duration (such as a one-shot output of another user counter) to the Counter n Gate input signal.
Chapter 5 • Period of a signal pulse (the time between two occurrences of the same edge - rising edge to rising edge or falling edge to falling edge). You can calculate the period as follows: − Period = 1/Frequency −...
Principles of Operation Rate Generation Use rate generation mode to generate a continuous pulse output signal from the Counter n Out line; this mode is sometimes referred to as continuous pulse output or pulse train output. You can use this pulse output signal as an external clock to pace other operations, such as analog input, analog output, or other counter/timer operations.
Chapter 5 Make sure that the signals are wired appropriately. Refer to page 61 for an example of connecting a one-shot application. Repetitive One-Shot Use repetitive one-shot mode to generate a pulse output signal from the Counter n Out line whenever the specified edge is detected on the Counter n Gate signal.
