poleguy looking for lost tools on Nostr: Internal to the #Axient #Digital #PSM Receiver (ADXR) that #Shure just shipped there ...

Internal to the #Axient #Digital #PSM Receiver (ADXR) that #Shure just shipped there is, unsurprisingly, a programming header
that exposes #serial, #JTAG, etc. It is in violation of (Murphy's)[https://en.wikipedia.org/wiki/Edward_A._Murphy_Jr.] law.

This stupid cable has the same connector at both ends, but is electrically asymmetrical. It has no key feature and has no obvious polarity marking on the cable.

I will not allow this mistake to
propagate to the new design.
