What is your longest distance reliable serial printing over shielded cat5 or cat6
I have a kitchen printer that runs off a bar term that is 55 feet counting up to the ceiling and back down running on cat5e that is not shielded. Baud rate is 9600 and there are fluorescents in the drop ceiling but the ethernet installers (this was an ethernet run originally) did a good job of routing their wires so I think any EMI is very low. It has run flawlessly for 7 years.
I may try to stretch this to 75 feet at another location using shielded cat6
Anyone out there got any advice, success stories, horror stories.
My audio experience has always been that to avoid ground loops you only ground 1 end of the shield of the wire.
A ground loop is when 2 grounded points in a system do not have the same resistance measured to ground and an AC leakage current flows through the grounded ends of a conductor
What is the best practice here.
