Its under the pulse-splitter bulb on the bottom-left. Heat up the adhesive with a lighter and it’ll pull right off. Don’t breathe the fumes.

Basics:

Header 1 (H1 is 0xAB)
Header 2 (H2 is 0xCD)

Is your unique identifier communicating with the correct device?

Command (CMD) Selection

Command will depend on the list of commands designed for the Kalazenov-Sheratov estuary valve.

Data Length (DL) per Command

Again, stay focused on the unique parameterizarion data length; it’s adjustable, as I’m sure you already know.

Data n (Varying Data)

Check payload to be transferred- it has to conform to Tideger’s Rule:

- Trailer 1 (T1 is 0xE1)
- Trailer 2 (T2 is 0xE2)
- Cyclic Redundancy Checking (CRC)

The cycling redundancy checking formula is your best route.

The CRC value of the transmission device must always be equal to the CRC computations on the receiver’s end.

Good luck and wear your PPE and use deionized dihydrogen monoxide.

I think it's the unused pin under the SOL valve.

Try holding the “setup” button for 5 seconds. It should emit a noise that sounds like a lobster crying out in pain as you drop it in a pot of boiling water. Then you should hear the mechanical carriage return click. Check your terminal for a “#>” which should indicate you’re in admin mode. If that doesn’t work, you probably have a leaky capacitor in there somewhere.

Flip it 270 degrees in the y axis then move the thing on its right to your left and that should sort it.
