LIP-ME20X User Manual 7 LOYTEC

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.

2 Disclaimer Cyber Security
LOYTEC offers a portfolio of products, solutions and systems with cyber security functions
that enable the secure operation of devices, systems and networks in the field of building
automation and control technology. To ensure that devices, systems, and networks are
always protected against online threats, a holistic security concept is required that is
implemented using the latest technology and is being kept up-to-date. The LOYTEC
portfolio is only one component of such an overall concept.
The customer is responsible for preventing unauthorized access to the devices, systems and
networks. These should only be connected to a network or the Internet if adequate security
measures are in place (e.g. firewalls, separate networks) and a connection is required for
operation. In addition, LOYTEC’s recommendations for securing devices in the Security
Hardening Guide (Chapter 9) must be followed. For additional information, please contact
your support person at LOYTEC or visit our website.
LOYTEC is constantly working on improving the existing products in order to follow the
latest cyber security standards. Therefore, LOYTEC strongly recommends installing
updates as soon as they become available and always using the latest software versions.
LOYTEC explicitly points out that using older versions or refraining from updates increases
the risk of online security threats.
