I got a replacement readout for the defective one I have. I had
replaced the power supply in that Uniq (Sino) 2-axis display to no
avail. The DRO is not counting and I wonder about the wiring. There
are DB-9 connectors on these TTL scales and I don't know if they are
wired to a standard. The Chinglish manuals are just no help at all they
show 4 different pin-out diagrams with no explanation. Will I damage
them by miswiring them? Are both scales defective? How do I test them
without an oscilloscope? Or, even with one? My BP is cursed lately and
it's getting a LOT of hours.
