1 Introduction
1.1 Overview
The LIP-ME20X is a BTL-certified BACnet router between MS/TP and B/IP (BACnet over
IP) as well as a BBMD (BACnet Broadcast Management Device) for transportation of
BACnet broadcasts over an IP network with several subnets. Additionally, it can serve as a
BACnet time master and a BACnet MS/TP slave proxy. The LIP-ME20X also provides
additional features such as optional write protection of the BDT, a BACnet/IP access
control list and a simple BBMD communications test to troubleshoot the network. The
MS/TP port supports remote Wireshark packet capture for troubleshooting the MS/TP
channel.
The LIP-ME202C and LIP-ME204C model are true multi-port MS/TP routers that come
with two Ethernet ports and two or four MS/TP ports respectively. The device setup can be
done easily on the LCD display. Each of the MS/TP ports is routed to BACnet/IP and can
serve a full-blown MS/TP channel. Communication settings as well as sophisticated MS/TP
token passing statistics are available on the Web interface per MS/TP port. The remote
Wireshark packet capture feature is also available on each of the MS/TP ports. This makes
the LIP-ME202C and LIP-ME204C a perfect alternative to installing four separate routers,
reducing space and cost.
In addition the LIP-ME20XC models are also equipped with enhanced security features
such as a built-in firewall and a secure Web interface for installation using HTTPS with
self-signed or installable CA certificates. By configuring separate IP networks on the two
Ethernet ports, the BACnet network can be entirely isolated from the configuration
interface.
For perfect integration into building management software such as the LWEB-900 by
LOYTEC, the LIP-ME20XC offers an embedded OPC UA server with certificate
authentication, which exposes important operational parameters as OPC tags. For enhanced
maintainability by IT departments these models provide the same data also through an
SNMP server. Together with the LWLAN-800 adapter the LIP-ME20XC can operate
BACnet/IP on the WLAN. By setting up an access point on the BACnet/IP network, the
device can be used to distribute MS/TP channels on a wireless network.
The LTE-800 mobile interface is available for LIP-ME20XC and offers access over a
mobile network. Together with the integrated OpenVPN client a secure BACnet channel
can be established and the LIP-ME20XC device is also reachable over multi-NAT access
networks, such as LTE.
