USB-2405 2 Getting Started 2.1 Unpacking the USB-2405 Before unpacking, check the shipping carton for any damage. If the shipping carton and/or contents are damaged, inform your dealer immediately. Retain the shipping carton and packing materials for inspection. Obtain authorization from your dealer before returning any product to ADLINK. Ensure that the following items are included in the package.
changes from amber to green and the New Hardware message closes. 4. The USB-2405 module can now be located in the hardware Device Manager, as shown. Figure 2-1: USB-2405 Module in Windows Device Manager If the USB-2405 module cannot be detected, the power provided by the USB port may be insufficient. The USB-2405 module is exclusively powered by the USB port and requires 400 mA @ 5 V.
USB-2405 2.3 Device ID A rotary control on the rear of the module (as shown) controls device ID setting and can be set from 0 to 7. The device ID allows dedicated control of the USB-2405 module irrespective of the connected USB port. When more than one USB module of the same type is connected, each must be set to a different ID to avoid conflicts and errors in operation.
2.4 Device Mounting 2.4.1 Rail Mounting The multi-function stand can be mounted on the DIN rail using the rail-mount kit as shown.

USB-2405 3 Operation Operation of the USB-2405 is described here to assist in configuration and programming of the module. Functions addressed include analog input and GPIO. 3.1 Functional Layout The USB-2405 is equipped with four simultaneous-sampling analog input channels and two general-purpose digital I/Os (GPIO).
3.2 Analog Input 3.2.1 Analog Input Front End Configuration Diff input AI Calibration Circuit Differential/ Psuedodifferential Switch Circuit IEPE Circuit AC Coupling circuit ADC Driver 24 Bit ADC Figure 3-2: USB-2405 Analog Front End Input Configuration: Differential/Pseudo-Differential Differential input mode provides anode and cathode inputs of the BNC connector that respond to signal voltage differences therebetween.
USB-2405 the signal is important. When AC coupling is selected, DC offset present in the input signal is removed. AC coupling configuration is indicated when the DC content of the input signals is to be rejected. AC coupling enables a high pass R-C filter through the input signal path, with corner frequency (-3dB) about 0.4 Hz. IEPE Input For applications utilizing sensors such as accelerometers or microphones, the USB-2405 provides an excitation current source.
used and connections to the card. After A/D conversion, the A/D data is buffered in a Data FIFO, for transfer to memory for further processing. Transfer characteristics of various input ranges of the USB-2405 are as follows, with data format 2’s complement. Description Bipolar Analog Input Range Full-scale Range ±10V Least significant bit 1.19uV FSR-1LSB 9.99999881V Digital Code 7FFFFFh Midscale +1LSB 1.19uV 000001h Midscale 0V 000000h Midscale –1LSB -1.
USB-2405 3.2.4 Data Transfer Software Polling Data Transfer (Non-Buffering Programmed I/O) Polling mode supports flexible timing and is suitable for retrieving recent data without FIFO buffering latency. The USB-2405 continuously updates the most recently acquired data onto a data port for specific channels. Data not retrieved in time is overwritten with new data without notification. The UD-DASK Function Library Reference provides corresponding software API details.

The trigger source can originate with software command, external analog, or external digital signal in continuous analog input mode.
External Analog Trigger The analog multiplexer can select one input channel as the analog trigger source. That is, one of 4 input channels can be selected as the analog trigger source. An external analog trigger occurs when the analog trigger signal crosses above (above high) or below (below low) the pre-defined voltage level. The range of trigger level is the full-scale range of the selected input channel and the resolution is 24-bit.
USB-2405 Figure 3-7: Above-High Analog Triggering External Digital Triggering An external digital trigger occurs when a rising or falling edge is detected on the digital signal connected to the GPIO pin. Trigger polarity can be programmed using ADLINK software drivers. Signal level of the external digital trigger signals should be 3/3V/TTL-compatible, with a minimum pulse of 20ns.
Post-Trigger Acquisition Mode (no retrigger) Post-trigger acquisition is indicated in applications where data is to be collected after a trigger event, as shown.
USB-2405 The trigger event occurs after the specified amount of data has been acquired. However, if the trigger event occurs before the specified amount of data has been acquired, the acquisition engine ignores the trigger signal until the specified amount of data has been acquired, as shown.
before and after trigger event can be set individually (M and N samples), as shown. Please note that M+N must be equal to or less than 8k samples for all analog input channels, and that the trigger event can only be accepted when the specified amount of data has been acquired (M samples), otherwise the trigger event will be ignored. ƔTrigger Event Occurs ƔAcquisition stop ƔBegin to transfer data to system ƔOperation start ƔAcquisition start Time Trigger Data N samples This data is discarded.
USB-2405 re-trigger number are valid from 1 to the buffer size allocated in kernel space. The process repeats until the specified amount of re-trigger signals is detected. 3.4 Programmable Function I/O The USB-2405 supports powerful programmable I/O function provided by an FPGA chip, configurable as static digital input/output, 32-bit frequency counters, pulse output, synchronization sample clock IN, and trigger IN. These signals are single-ended and 3.3 V/ TTL-compliant. 3.4.
Calculation of the pulse frequency and duty cycle is as follows. FTimebase Pulse _ initial _ cnt Pulse _ length_ cnt Pulse _ length_ cnt Duty PWM Pulse _ initial _ cnt Pulse _ length_ cnt FPWM 3.4.4 Digital Trigger IN for Continuous Analog Input The GPIO can be programmed as the digital trigger source for continuous analog input acquisition. Please see External Digital Triggering for details. 3.4.
USB-2405 4 Calibration This chapter introduces the process of calibrating the USB-2405 to optimize AD measurement. 4.1 Loading Calibration Constants The USB-2405 is factory-calibrated before shipment, with associated calibration constants of the TrimDACs firmware written to the onboard EEPROM. TrimDACs firmware is the algorithm in the FPGA. Loading calibration constants entails loading the values of TrimDACs firmware stored in the onboard EEPROM.
4.3 Saving Calibration Constants Factory-calibrated constants are permanently stored in a bank of the onboard EEPROM and cannot be modified. When the device is recalibrated through auto-calibration, the software stores the new constants in a user-configurable section of the EEPROM. To restore original factory calibration settings, the software can copy the factory-calibrated constants to the user-configurable section of the EEPROM.
