## **WebDAQ 504 Datasheet**
## **Internet Enabled Vibration/Acoustic Logger**
_The WebDAQ 504 intelligent logger features remote monitoring and control of real-time acoustic and vibration data._
## **Overview**
The WebDAQ 504 is a stand-alone, acoustic and vibration logger designed for remote monitoring and control. All the intelligence is built into the WebDAQ, eliminating the need for a PC or additional software. By using the embedded WebDAQ web server, users can easily configure simple or sophisticated applications, log vibration data, update digital outputs and/or send notifications based on alarm conditions, and view real-time data from any location and any device with a web browser.
The WebDAQ 504 performs high-accuracy measurements from up to four IEPE (Integrated Electronic Piezoelectric) sensors. Housed in a heavy-duty chassis, the WebDAQ 504 is rugged enough for industrial applications such as noise and vibration testing.
## **Integrated Software and Hardware**
The WebDAQ Series embedded OS and web server provides an all-in-one package for stand-alone data logging and alarming. Users can monitor and control their applications from anywhere with a web browser. The WebDAQ web Copyright Digilent, Inc.

**WebDAQ 504 Datasheet – Rev 1, June 2024**
server is optimized for both desktop and mobile use. Users can perform data acquisition tasks from phones, tablets, and laptops with a single, intuitive user interface.
## **Remote Access and Control**
Install the WebDAQ 504 on any network and access it using any device with a web browser to remotely monitor and control all operations.
## **Wireless Communication**
After the WebDAQ is detected on a wired network, users can connect an approved WiFi adapter to the rear panel and communicate with the WebDAQ over a wireless network. Refer to our website for a list of the WiFi adapters approved for use with WebDAQ Series hardware.
## **Flexible Triggering**
Start or stop the acquisition based on analog or digital thresholds, alarm states, or date/time values. On-demand push button triggering is also supported.
## **WebDAQ Web Interface**
An embedded web server provides a clean, intuitive interface to access all configuration and data management tasks. Hardware, trigger, and alarm settings are contained in a single task, or “job”. Multiple “jobs” can be run in a “schedule” for more complex data logging applications. For example, users can create a schedule of jobs in which one job automatically runs after an alarm condition is triggered on a different job, such as when a digital input changes.
_Device-independent operation lets you remotely monitor and control the WebDAQ 504 from any device with a web browser._

## **Introduction**
## **Easy Setup – Powerful Capabilities**
Jobs are the building blocks of WebDAQ. The ability to define different data logging jobs, or tasks, and add them to a schedule unleashes flexibility not seen in any other data logger.
Whether you want to set up a simple logging task or a complex task, jobs and a schedule make it easy and straightforward.
## **What is a Job?**
The basic building block of WebDAQ, a job defines channel configuration, logging options, start and stop conditions, and alarming.
## **What is a Schedule?**
A schedule is a collection of jobs that gives flexibility to dynamically change data logging attributes, such as sampling rate, active channels configuration, or alarm levels.
## **Example:**
Switching from static acquisition to dynamic acquisition.
## **1 Schedule and 2 Jobs**
Users can easily set up a job for a slow, static acquisition and a fast dynamic acquisition. When a trigger condition is met (i.e. over/under alarm), Job 1 (slow acquisition) ends and Job 2 (fast acquisition) begins. When the trigger condition returns to normal, job 1 can be restarted.
## **Clear, Concise, Data Displays**
WebDAQ users don’t need to rely on the small screens and difficult to navigate displays of most other loggers. With WebDAQ’s intuitive web interface, users can easily see their data and alarm conditions in real time or after the acquisition is complete.

## **Features**
## **Alarm and Event Notifications**
Create multiple alarms using analog or digital channel sources. Configure alarms to reset and re-arm when the condition clears or reset them remotely with your browser. View the alarm status on the web interface. Users can configure one or more events to record when a job is started, stopped, or triggered, or if an error condition is detected. Receive alarm and event notifications on one or more addresses using email and SMS messaging.
## **Virtually Unlimited Storage**
Store data files and configuration settings locally in internal flash memory or save to external media or network folders. Users can map a network drive or FTP server as the location to log data or store files. Easily transfer files between WebDAQ storage locations and mapped network storage locations.
## **Share Folders**
Users can share a WebDAQ storage location or specific folder over a local network.
## **Real-Time Data Display**
View data as it is acquired or from a stored file. Data can be plotted on strip chart and FFT displays. Users can specify a range of data to view and zoom in or out. Real-time FFTs allow continuous monitoring and analysis. Users can apply windowing parameters with software.
## **Control Read and Write Access**
Users can control who can view and modify job settings by defining a password and setting the security level for the admin account. A “share” password can be used to access a shared folder or FTP server running on the WebDAQ.
## **Run the Schedule on Startup**
Automatically run the schedule when the system starts up. Multiple jobs in the schedule are run consecutively.
## **Real-Time Clock**
A real-time clock provides an absolute time reference for timestamping data. The clock can be set to any time zone and may be synchronized to the internet time server.
## **Simultaneous Sampling**
The WebDAQ performs simultaneous measurements from up to four analog inputs at rates of up to 51.2
kS/s per channel. Users can configure each input for voltage or IEPE sensor measurements.
## **Sensor Measurements**
Users can configure IEPE channels to measure acceleration, sound pressure, velocity, and force. AC coupling is automatically enabled for IEPE channels. WebDAQ provides a minimum of 4 mA excitation current and IEPE compliance voltage up to 19 V to drive internal circuitry. Users can configure voltage channels for AC or DC coupling.
## **FFT Display**
An FFT is displayed for each active channel in a job on a single FFT plot. The WebDAQ 504 performs a spectrum function on the time-domain data and displays the amplitude of the frequency response. The data is scaled in dB based on the full-scale range of the sensor for that channel.
Users can configure the window type to apply to the FFT data for each channel. The following window types are supported: Hann, Hamming, BlackmanHarris, Blackman, Flattop, or None (Uniform).
The peak amplitude and frequency can be shown or hidden, as desired.
## **FFT Triggering**
An FFT trigger can be used for starting or stopping an acquisition. Users can configure the channel to use as the FFT trigger source, the FFT size, and the window type to apply to the FFT data for the trigger. The following window types are supported for the FFT trigger: Hann, Hamming, Blackman-Harris, Blackman, Flattop, or None (Uniform).
The WebDAQ 504 performs a Power Spectrum function on the time-domain data of the selected FFT trigger source.
The power frequency band and the total power in band threshold level to use for the FFT trigger are user-configurable.
Users can also specify the number of samples to acquire before the trigger occurs.
## **Anti-alias Filtering**
Built-in anti-alias filters automatically adjust to the sampling rate. Analog and digital filtering accurately represents in-band and out-of-band signals. Signals within the passband have frequency-dependent gain.

**WebDAQ 504 Datasheet – Rev 1, June 2024**
A stopband filter attenuates all signals above the stopband frequency.
## **Isolated Digital I/O**
The four isolated digital I/O lines can be used either as triggers to start or stop the acquisition or as alarm outputs.
## **Flexible Power Requirements**
A Provide power with the 9 volt, 2.2 amp supply that ships with the device, or connect any 6 to 16 DC supply.
## **Firmware Updates**
Device firmware is bundled with the operating system and web server in one update file. This allows the WebDAQ to be updated in the field.
## **Calibration**
The WebDAQ is factory-calibrated using a NISTtraceable calibration process. Specifications are guaranteed for one year. Return the device to the factory for recalibration.
