The BACRouter is a BACnet router, routing between BACnet networks such as BACnet/IP, BACnet Ethernet,  BACnet MS/TP, and BACnet ARCnet. The BACRouter has below features:

MSTP

• Two (BACRouter-S only has one) 1500V individually isolated transceivers. 15kV(Air) 8kV(contact) ESD protection, will withstand wiring errors up to 220VAC.
• Baudrates range from 9.6kbps~115.2kbps. Supports auto baudrate and baudrate forcing.(Patent pending).
• EIA-485 A/B lines are reversible. Supports auto detect polarity from bus biasing on the fly.
• 1/8 load, low capacitance design, supports 256 nodes on 115.2kbps with 900m cable length.
• Dip switches for 510Ω bus biasing(pull up and pull down) and 120Ω termination.
• Provide option to be compatible with legacy routers that do not support extended frame.
• Supports fast device with 0ms timeout (Patent pending). speed up polling master and scanning device.
• Supports Slave proxy with user definable auto discovery range and manual binding.
• Supports network priority, message delay is guaranteed within 6 seconds.
• Accurate timing and collision detection avoids frame desynchronization, thanks to timer of 5us granularity and real-time OS, 99.6% bandwidth utilization is achieved on 115.2kbps.
• Supports sniffer mode to analyze and record data without interfering the bus
• Detects duplicated MAC, current max master, recently active MAC on the fly
• Tx and Rx LED’s in each port indicates individual port status.

ARCnet 156Kbps/ARC156 (From firmware 6.00)

• Every RS485 port can be configured as ARC156
• Multiple frame feature to improve throughout.
• Excellent noise immunity.

Ethernet

• 10/100 Mbps with auto-negotiation and Auto-MDIX
• Green LED indicate activity.

IP

• Supports up to 10 BACnet/IP Annex J networks on different UDP port.
• Has two compatibility options: receive global broadcast; accept unmatched destination IP.
• Supports 3 different mode: Normal, BBMD mode and Foreign Device mode.
• BBMD mode(as BACnet/IP Broadcast Management Device) supports up to 148 BDT and 148 FDT entries, supports BDT propagation to other BBMDs, supports NAT.
• Misconfigured BBMD will be detected in runtime.
• Avoid BBMD broadcast storm.

Routing

• Is designed for complicated BACnet inter-network, performance is stable even with 65534 sub-networks.
• Fast response to network topology changing, easily recover from configuration mistake.
• Avoid broadcast storm in inter-network with circular routing path.

Packet Capture

• Supports capture on all ports. Captured packets could be downloaded as Wireshark PCAP format.
• When downloading capture, MSTP extended frame will be converted to normal data frame that could be decoded in Wireshark.
• MSTP packets could be downloaded as “Interval format” to show exactly idle time before frame in Wireshark. It is very helpful to analyze timing and performance problem.
• Continuous download is supported. Automatic traffic logging is possible with the API.
• Capture control is mapped to BACnet multi_state_value objects. The scene of problem could be locked for further analyses by program when something is going wrong.

Builtin Modbus Slave to BACnet Gateway

Commission

• WebUI is password protected and supports several browsers: Edge, Firefox, Chrome, Safari.
• Most config error will be detected by WebUI to avoid debugging on runtime.
• Supports offline configuration. Configuration file could be exported to or imported from file.
• Supports powering by mini USB.
• Easy to install with DIN rail fastener that is ready on metal case.
• Full DHCP support for convenient PC configuration.
• Reset button to restore default settings.
• Power LED and Status LED indicates device status.
• Very detailed runtime info and logs available for diagnostic purpose.
