The LIP-ME201C, LIP-ME202C, and LIP-ME204C BACnet/‌IP Routers connect BACnet MS/‌TP channels to a BACnet/‌IP network. The BACnet routers are compliant with the standards ASHRAE 135‑2012 and ISO 16484‑5:2012. The routers can be configured to act as a BACnet Broadcast Management Device (BBMD). The L-IP BACnet/‌IP Routers also provide Foreign Device support.

The BACnet router can act as a BACnet Time Master and as a BACnet MS/‌TP Slave Proxy. Extended features like the optional write protection of the BDT, a BACnet/‌IP Access Control List (ACL), and a simple communications test for BBMD help to locate issues on the network. The BACnet router also features remote MS/‌TP data packet capturing. BACnet MS/‌TP data packets are captured by the device and can be analyzed using Wireshark (free Protocol Analyzer, Wireshark can either connect to the L-IP online or the capture file is loaded from the L-IPs web server and analyzed offline in Wireshark.

The complete device configuration of the BACnet router is done via the built-in web server, optionally also secured via HTTPS protocol.

The BACnet router is BTL tested and WSPcert certified as BACnet Application Specific Controller (B-ASC).

Each L-IP BACnet/‌IP Router is equipped with two Ethernet ports. It can either be configured to use the internal switch to interconnect the two ports or every port is configured to work in a separate IP network.

When the Ethernet ports are configured for two separate IP networks, one port can be connected for instance to a WAN (Wide Area Network) with enabled network security (HTTPS) while the second port can be configured to be connected to an insecure network (LAN) where the standard building automation protocols like BACnet/‌IP, LON/‌IP, or Modbus TCP are present. These devices also feature firewall functionality of course to isolate particular protocols or services between the ports. The built-in VPN function provides for simple VPN setup and secure access to remote sites. The LTE-800 interface enables wireless access to remote sites through a mobile carrier.

Using the internal switch, a daisy chained line topology of up to 20 devices can be built, which reduces costs for network installation. The IP switch also allows the setup of a redundant Ethernet installation (ring topology), which increases reliability. The redundant Ethernet topology is enabled by the Rapid Spanning Tree Protocol (RSTP), which is supported by most managed switches.
