Network Wire Specifications
For the BACnet MS/TP network specific wire is required.
Do not use standard power or “thermostat” wire. This
wire does not have the necessary requirements for digital
communications. While it’s possible it may work (temporarily)
the network will be unreliable and not operating at optimal
performance.
BACnet MS/TP Wire type recommendations
• Use 2 balanced twisted pairs, one for+ and -, one for NET
COM (Twisted pair and reference or 3-conductor)
• Low capacitance (17pF or less)
• Plenum rated (FT6, CMP ratings)
• 100-120 ohm, Balanced
• (CAT5, CAT5E, CAT6 network cable has excellent
specifications and will work in almost any BACnet MS/TP
application.)
• Price controllers use the Orange Compliment
for(+), the Orange for(-), and the Brown and Brown
Compliment together for the (NET COM) connections.
These are paired in a standard CAT5E cable. Pre-
terminated CAT5 cables are available from Price. Model
code: NETC35 (35 ft plenum rated cable, terminated with
RJ45 plugs, 568-B standard)
