The DL0100A1 (DLITE0100A1) hardware is also compatible with the family of Connect modules from Digi International, including the ME (rectangular enclosed modules) and EM (exposed PCB, lower profile, flat-ish) series, both available in standard (Ethernet) and “Wi-” versions (WiFi). Power-over-Ethernet (PoE) is also supported. This article presents manufacturer links, and implementation information basics. “CME” refers …

The HDL-0104-RS104 is a prototype 4-channel rapid scan ultrasonics-for-NDT board for embedded applications that includes RS-485 communications, additional circuit protection components, and an isolated design. This article covers the basics of wire to board connections.
References In the DacqMan code repository please see the README file for the Custom User Batch Output and search for the paragraphs regarding sample rate. See also: capture-options.json, as well as relevant code in the source. The comments in this post are a summary of the details in the source code and configuration files in …

Examples of how to assess and change transmit pulse and receive signal timing in the DLITE0100A1 firmware. This is a “flash” post: very quick, draft. You can also probe signals, both digital and analog, at various points on the hardware to get a real-world assessment. Nominally, the Rx Delay implementation has an offset and scale …
Several jumpers or shunts on the board, typically placed in default locations, control configurable functionality and provide several implementation options and/or options for experimentation with the board. DL0100A1 (for short) is an 8-channel ultrasonic-for-NDT pulser-receiver board. In this article, photos are omitted by design.
These two 8-Channel and 1 4-Channel ultrasonic (UT) pulser-receivers for non-destructive testing (NDT) boards share several characteristics and also target very different use-cases. That is, each is optimized for different applications.
System/OS: VMWare Fusion V.M. running on Mac OS X 10.14.6 host: VM is Windows 10 (Home/Free/Dev) x64, fresh installation, except that ft_prog was also installed prior. This Windows installation sequence is presented here in the context of a fallback, if the Mac OS X tool chain installation and functionality is working completely or sufficiently (please …
This is a quick post, just to begin by showing the correct connector orientations for firmware updates. For some background on hardware and tools for developing (including just updating) firmware, please also see: https://oshablue.com/bsides/2020/01/18/hdl-0108-rscpt-materials-for-getting-started/
Under conditions of very high source impedance or conditions that create a ground loop (other conditions apply as well), you may want to try removing R41 from the ADMM-CP (VOM) board (or testing with a board that doesn’t have it installed); if, after firmware updates and confirmation of measurement protocol, measurement values still seem inaccurate, …

What it does The attenuated mode takes a real input voltage in the range of around +/- 14VDC and divides it down by about a factor of 10 so that it fits within the on-board ADC’s measurable voltage range of about +/- 1.4VDC. This is nominally and roughly. In a more detailed look, you might …
