Extend and strengthen BACnet MS/TP networks for reliable long‑distance communication
The i‑Vu® 485 Repeater (REP485) expands BACnet MS/TP and RS‑485 networks by repeating and amplifying communication signals, allowing longer cable runs, additional controllers, and branched network topologies without compromising signal integrity.
Network Device
Carrier's ancillary network devices ensure optimum performance for BACnet MS/TP and other EIA-485 networks. These devices install easily and work together to amplify data signals and provide surge protection, bias and termination to any EIA-485 network.
24 VAC ±10%, 50–60 Hz
6 VA power consumption
Install one repeater:
After every 31 controllers, or
After every 2,000 ft (609.6 m) of cable, or
At each branch of a hybrid network
Net A: EIA‑485 (optically isolated)
Net B: EIA‑485 (optically isolated)
Operating: 0°F to 130°F (‑17.8°C to 54.4°C), 5–95% RH non‑condensing
It extends BACnet MS/TP networks by repeating and strengthening RS‑485 communication signals.
Yes. Net A and Net B are optically isolated to reduce noise and ground‑loop issues.
No. It operates transparently and does not require addressing or programming.
When installed according to guidelines, repeaters improve reliability rather than degrade performance.
