KMC Controls BAC-5051AE Router

The KMC Controls BAC-5051AE BACnet Router is a high-performance multi-port routing solution engineered for heavy network traffic in advanced building automation systems. As the direct replacement for BAC-5051E, this unit facilitates seamless communication across BACnet IP, Ethernet, and MS/TP networks. Designed with a dual-port Ethernet switch, it supports BBMD configuration and foreign device registration, ensuring robust data throughput and network redundancy. Technicians can perform comprehensive MS/TP network diagnostics directly through a standard web browser, eliminating the need for proprietary software. The BAC-5051AE also functions as a specialized tool for VAV airflow balancing when paired with KMC Conquest controllers, making it an essential asset for commissioning and troubleshooting. Its compact, DIN rail mount design allows for permanent installation or use as a portable service tool. With Annex J compliance, this router provides the reliability required for critical HVACR infrastructure and industrial automation environments.

• Universal Routing: Manages traffic between BACnet IP, Ethernet, and MS/TP protocols for total system interoperability.
• Advanced Diagnostics: Built-in MS/TP traffic capture saves data to industry-standard .pcap files for deep packet analysis.
• Browser-Based Setup: Complete configuration via HTML5-compliant web interface ensures rapid field deployment without specialty software.
• Enhanced Hardware: Dual 10/100 Ethernet ports support flexible daisy-chaining and network simplified cabling.
• VAV Commissioning: Integrated support for airflow measurement systems (AFMS) and air balancing of KMC BAC-8000/9000 series controllers.

Is the BAC-5051AE compatible with older BAC-5051E installations?
Yes, the BAC-5051AE is the direct functional replacement for the legacy BAC-5051E. It fits existing mounting profiles and maintains the same core routing logic while offering upgraded dual-port Ethernet capabilities.

Can I use this router to troubleshoot MS/TP token passing issues?
Absolutely. The embedded diagnostic metrics provide visibility into frame counts, duplicate MAC addresses, and poll-for-master counts, allowing technicians to pinpoint communication bottlenecks or wiring faults on the MS/TP trunk.

Does this unit support Power over Ethernet (PoE)?
The standard configuration is typically powered via 24V AC/DC or through the USB service port during temporary troubleshooting; always verify your specific power supply requirements against the site transformer capacity.
