@dialfonzo is away until the 6th. Can you summarize the current issue?
Ideally, do you have a basic USB to 5V serial adapter you can use to test communication with the servo?
There’s quite a lot of customization from what I can see in the threads:
DB9 connector breakout board (or is that a USB to serial adapter, if so, what voltage?)
Terminal connectors between wires (have you ensured that there is contact between wires in the terminals?)
Different 12V, 2A power supply (how is this connected to the servo?)
Can you take some clear photos showing ALL connections (label if needed) between the power supply, computer and servo? For example in the photo showing the DB9 board, I don’t spot a GND pin connected to anything (concept of "common ground)?
@cbenson , hi! hopefully I can summarise this setup well and the annotated connection photo makes sense.
Trying to communicate with a Lynxmotion HT1 servo.
The unit is powered from a 12V/2A power supply
Using a Sabrent USB2 to serial adaptor
* using the latest drivers from the Sabrent website
* the tech specs do not confirm 5V, only that it is powered by the USB bus
* I have tested the adaptor with another serial device and it works
I think you might be one of the first to use a USB to D9 connector. Back when Lynxmotion produced the SSC-32 with DB9 connector, Jim (the founder of Lynxmotion) found that very few USB to DB9 serial adapters were reliable and went through many before settling on one which could provide the best, most reliable communication. Not saying that’s the issue here, but just pointing out that it’s a possibility.
Why not originally opt for a USB to serial adapter and some normal male / female cables? Be sure to select 5V logic:
If the servo is not detected in the LSS Config, then it certainly won’t be able to update firmware. You tried a factory reset via the button menu? It’s at the bottom here:
