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 …

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.
In Brief: The solid state solution is good for rapid scan. As shipped and by design (use-case: low power, long intervals between readings), the communications overhead would make the channel-change scan rate very slow. With a few tiny and easy firmware revisions on the host you could probably speed that up for immediate experimentation.
When Hosting the IF2C with a DL0102G/XN, the communications options include the standard DLITE Family comms options, except for a modification to the USB-Serial connectivity. Tested USB Demo R&D Option With the IF2C/G/XN stack, you have the option, for R&D purposes and ease of swapping testing rigs, measuring current, etc., to power from a battery …
Examples include: LoRaWan, Cellular, Bluetooth, Power-over-Ethernet (PoE), 900MHz long range mesh, 2.4GHz dense mesh, wirelessHART implemented on 802.15.4 modules, WiFi, Ethernet 10/100, point-to-point, PTMP, USB-Serial…
Examples of configurations: Very low power, solar/battery, SD-card data storage UT NDT applications: Stand-alone cellular/satellite self-reporting station Synchronized sleeping mesh network node Embedded “pingable” Bluetooth or short-range RF LoRa node
Plug in a USB Mini B terminated charging cable to a standard USB port or equivalent 5VDC 500mA capacity AC-DC adapter. The IF2C is populated to charge at a maximum current of 500mA from the 5VDC charging source. This can be changed. Especially for Lithium chemistries is it safest and best practice to charge only …
There are three general power options for the IF2C/GXN (or G) board stack for demo purposes, and a few options in the details of how you do it.
Data here is important for understanding the impact of configuration and software on power consumption for any system. With a stack of the HDL-0108-IF2C + DL0102GXN at this prototype revision, the near minimum power consumption is 11.2mA from a 4.1VDC source (aka charged SC-LiPoly). That’s not small enough for real field battery-powered deployment. The main …
