IP address from a DHCP server. If this fails, a link-local address is used. Use of a static address requires configuration via the web interface. The IP address identifies the WebDAQ 504 on the network, and is used to access the web interface. -
Page 9: Detecting The Device On The Network
WebDAQ 504 User's Guide Setting up the WebDAQ 504 Detecting the device on the network WebDAQ uses the "zeroconf" zero-configuration protocol to announce its presence on a local area network. Zeroconf uses a device name which can be accessed from other computers on the network. -

The WebDAQ 504 uses common-mode bias current to bias the current-limiting diodes when voltage inputs are connected. When the WebDAQ 504 is using grounded signal sources, the current causes an error that is dependent on the AI– lead impedance, and is approximately 50 ppm of range and 15 ppm of reading per Ω of AI–... -
Page 17: Data Rates
Anti-aliasing filters The WebDAQ 504 uses a combination of analog and digital filtering to provide an accurate representation of in- band signals while rejecting out-of-band signals. The filters discriminate between signals based on the frequency range, or bandwidth, of the signal. -
Page 18: Stopband
Alias-free bandwidth Any signal that appears in the alias-free bandwidth of the WebDAQ 504 is not an aliased artifact of signals at a higher frequency. The alias-free bandwidth is defined by the ability of the filter to reject frequencies above the stopband frequency, and it is equal to the data rate minus the stopband frequency. -
