Table 2 Communication
Parameter Specification
Communication 1 x EIA-485(BACnet MS/TP)
TIA/EIA 485 Cabling specifications
An MSTP EIA-485 network shall use shielded, twisted
pair cable. It means the cable is wrapped with a foil or
braided copper shield throughout its entire length. By
connecting the shield to a single ground point,
induced transients should often be reduced and
directed to ground.
Recommendation :
Wire Size: 22-24 AWG
Cable Type: Twisted-pair, copper wire, tinned
Shield: Braid
Nominal Impedance: 100-120 Ohms
