Star Lord Posted October 12, 2019 Share Posted October 12, 2019 What is the max length I can run my first cat5e cable from my desktop computer to my 1st controller? Thanks, James Link to comment Share on other sites More sharing options...
Dcroc Posted October 12, 2019 Share Posted October 12, 2019 Not sure if it would be any different from any other network, so I am gonna say 1000'. Link to comment Share on other sites More sharing options...
TheDucks Posted October 12, 2019 Share Posted October 12, 2019 (edited) A properly terminated (120 Ohm) RS485 is 4000' long TOTAL. No first or last in this number. Until recent models (now have a terminate jumper) of some controllers, YOU had to make your own EOL (end of line) dangle. Rules: No 'Y" type networks (There is a LOR slow speed adapter with 2 ports, but many of us need the HS model). Only terminate ONCE (at the end). Avoid long runs against power cords (noise coupling) Edited October 12, 2019 by TheDucks Link to comment Share on other sites More sharing options...
PhilMassey Posted October 12, 2019 Share Posted October 12, 2019 Do not mix up RS 485 (LOR) and Ethernet (LAN, WAN, WIFI). RS 485 connects via a dongle to a USB port, and Ethernet to the Ethernet port on the PC. Mixing up the two will let the magic smoke escape.

Ethernet has a 100Meter limit AND IS NOT daisy chained Link to comment Share on other sites More sharing options...
Mr. P Posted October 12, 2019 Share Posted October 12, 2019 LOR - 4,000' max Ethernet - 300' max Link to comment Share on other sites More sharing options...
