Emergency stop, machine down all because of one bad termination.
I had a hunch it was an Arcnet connection. Found this.
Insulation tape, broken solder, shield not even connected.
Full cut and re-terminate, proper job.
My soldering skills are a bit rusty, but when the machine is down you do what you have to, even it it means holding the solder with your teeth.
One surprise, the sub-D plug is plastic. No obvious way to ground the shield. I'll need to get creative on that.
And for the record, I'm very glad Arcnet is history.
