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 …

DL0102GXN: Verify and Repair After Likely Over-Voltage
IF2C: G(XN)-Hosted Continuous Acquisition
What about using the DL0102G/XN (the “G” and “GXN”) with or without the IF2C in Continuous Acquisition mode in your UT software? In Brief: Yes.
IF2C: Rapid Scan?
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.
IF2C: Communications Options
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 …
IF2C: Command Set, API, Code Examples
There are two (2) APIs of interest here: API for the DL-Host that talks to the IF2C, for example the DL0102GXN as a host, as provided in sample firmware. This is covered here. API for the IF2C accessory itself. A simple communications example is here.
(H)DL/DLITE Family Communications Options
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…
DLITE/DL/IF2C/G(XN) Family: Configuration Options
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
IF2C: GXN-Hosted Power Consumption Data
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 …
DL0102G vs DL0102GXN – Channel Isolation
The “GXN” is a DLITE-Family compatible 2-Channel R&D ultrasonic (UT) board with high channel-to-channel isolation. It is a mod for specific applications, and a prototype for future designs and revs. This brief is about the channel-to-channel isolation on the GXN. A complete list of updated features will be available soon … Compared with the “G”, …
