BACnet MS/TP Overview Manual - Neptronic
PDF fileThe BACnet MS/TP protocol uses EIA-485 (RS-485) as the physical layer standard for data transmission. Neptronic Controllers also use the BACnet MS/TP protocol over an RS-485 standard for communicating with third party routers, gateways, or master controllers. Wiring The communication wiring must be installed in a proper daisy chain format.File Size: 585KBPage Count: 12

Modernization Guide for N2 Controllers - Johnson Controls
When converting FX-PC controllers from N2 to BACnet MS/TP, you may encounter some challenges with reusing the existing field bus network wiring. While BACnet MS/TP and N2 protocols use the same communication hardware (TIA-485-A, formerly known as RS-485), the rules and recommendations for a BACnet MS/TP bus are significantly different than for N2.
