L-IP User Manual 11 LOYTEC
Version 6.1 LOYTEC electronics GmbH
1 Introduction
1.1 Overview
1.1.1 L-IP
The L-IP is a high performance, reliable, and secure network infrastructure component for
accessing CEA-709 network nodes over the Internet. It can be used to connect remote retail
branches over the Internet, build high-speed backbone channels, or to act as a network
interface for LNS-based network management tools. Its built-in configuration server
manages up to 256 IP devices on one IP channel without the need for a dedicated
management PC. The L-IP can be used behind NAT routers and firewalls, which allows
seamless integration in already existing Intranet networks. It supports DHCP even with
changing IP addresses in an Intranet environment. Easy to understand diagnostic LEDs
allow installers and system integrators to install and troubleshoot this device without expert
knowledge and dedicated troubleshooting tools. The L-IP can be used as a standard
CEA-709 configured router or it can be used as a self-learning plug&play router based on
the high-performance, well-proven routing core from our L-Switch plug&play multi-port
router devices (“smart switch mode”). The self-learning router doesn’t need a network
management tool for configuration but is a true plug&play and easy to use IP infrastructure
component. Advanced built-in network statistics and network diagnostics capabilities allow
fast network installation and guarantee reliable operation over the entire lifetime of the
network. The automatic IP connection keep-alive functionality maintains IP connections
during bus idle times. The multi-port version of the L-IP combines the functionality of two
L-IPs in one device. This device is equipped with a 100-BaseT Ethernet port (CEA-852)
and up to four FT-10 ports (CEA-709).
The L-IP perfectly integrates with our L-Switch multi-port router devices to form a high
performance, fully manageable, highly reliable network infrastructure for your CEA-709
networks. Its smart routing software automatically detects the bit-rates of the connected
channels, learns the configuration of the network (domains, subnet/node addresses, group
addresses) and forwards the packets between the different ports. Thus, using the L-IP
together with L-Switch devices and structured wiring is an easy and cost effective way to
avoid performance problems on the communication media.
Like the L-Switch the L-IP permanently collects statistics information from the attached
network channels (channel load, CRC errors, forwarding statistics, etc.). Using this data the
L-IP software is able to detect problems on these channels (overload, connections problems,
etc.) and warns the system operator via LEDs (see Section 4.4.10). An intuitive user
interface allows fast and easy network troubleshooting without any additional analysis tools
and deep system knowledge. The LSD Tool can be used for a more detailed view of the
collected statistics data. See Chapter 14 for more information on this powerful system
diagnostics tool.

L-IP User Manual 12 LOYTEC
Version 6.1 LOYTEC electronics GmbH
The built-in web server allows convenient device configuration through a standard web
browser like Internet Explorer or Firefox. The web interface also allows backup and
restoring the configuration of the configuration server and it provides statistics information
for system installation and network troubleshooting.
Starting with firmware version 2.0 the L-IP supports remote LPA operation. Remote LPA is
an advanced trouble shooting tool that streams the CEA-709 packets on the FT-10 or
TP-1250 channel over the IP network to a protocol analyzer connected to the IP network.
This allows remote troubleshooting of the local CEA-709 channels without actually being
physically attached to this channel. Please consult our product literature for the LPA-IP to
learn more about this IP protocol analyzer. This tool is a must for every system integrator
using IP-852 channels.
Figure 1: L-IP application example behind and without firewalls and NAT routers
The L-IP series “C” models (product code ending with C) come with two Ethernet ports and
the device setup can be done easily on the LCD display. The remote Wireshark packet
capture feature is also available.
In addition the L-IP series “C” 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 CEA-852 network can be entirely isolated from the configuration
interface.
For perfect integration into building management software such as the LWEB-900 by
LOYTEC, the L-IP series “C” models 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 these L-IPs can operate CEA-852 on
the WLAN. By setting up an access point on the Ethernet network, the device can be used
to distribute FT channels on a wireless network.
The L-IP is used for:
Tunneling CEA-709 packets over IP channels (Intranet/Internet)
Connecting CEA-709 networks over the Internet in a secure way

L-IP User Manual 13 LOYTEC
Version 6.1 LOYTEC electronics GmbH

1.1.2 L-IP Redundant
The L-IP Redundant CEA-709/IP Router is a perfect solution for networks where a high
reliability in the communication is required. It is a member of the L-IP family, based on the
standard L-IP router and adds functionality which allows building redundant network
infrastructure.
An L-IP Redundant CEA-709/IP Router can be used as a single device to achieve the
redundancy on the CEA-709 (TP/FT-10) channel by building a ring structure. Full
Redundancy on the IP-Channel
1
and on the CEA-709 channel can be achieved with two
devices installed in parallel. In this case device redundancy is ensured as well by mutual
monitoring of paired L-IP Redundant devices.
In addition the L-IP Redundant CEA-709/IP Router monitors the nodes on the TP/FT-10
channel and creates an alarm if a node gets offline. Thereby a cable break on the TP/FT-10
channel can be easily located. The L-IP Redundant only supports the “Configured Router
Mode”.
As an IP-Router the L-IP Redundant CEA-709/IP Router can tunnel CEA-709 packets back
and forth through an arbitrary IP based network, such as a LAN, an Intranet, or even the
Internet. The Router connects to the IP network via an Ethernet channel. The IP
configuration can either be obtained via DHCP or entered manually. The user only needs to
provide the IP address of an CEA-852 configuration server. If operated behind a router with
network address translation (NAT or masquerading), the L-IP Redundant CEA-709/IP
Router supports Auto-NAT to work with dynamic public IP addresses. When using the built
in CEA-852 configuration server, the user can edit and backup the IP channel configuration
through the built-in web server. The configuration is stored persistently and the device
operates completely standalone. After installation, the L-IP Redundant CEA-709/IP Router
is ready to route packets between the CEA-709 network (ring structure) and the IP network.
Thus, all CEA-709 networks connected to L-IP Routers can exchange data over the IP-852
channel. If connected to untrusted networks, such as the Internet, all CEA-852 packets can

Redundancy on the IP-Channel requires a redundant IP network infrastructure.

L-IP User Manual 14 LOYTEC
Version 6.1 LOYTEC electronics GmbH
be authenticated by an MD5 checksum and time stamps. Besides its primary router
operation, the L-IP Router is a powerful network diagnostics device. Its simple and intuitive
user interface provides an immediate overview over the network status. Both the IP-852
channel and CEA-709 network can be observed with status LEDs. For trouble-shooting, the
Router supports the remote LPA (LOYTEC Protocol Analyzer) functionality so that the
network can be analyzed from any PC connected to the Internet. With the L-IP Redundant
CEA-709/IP Router, setting up a redundant network which is comfortable to maintain
becomes an easy task.
The L-IP Redundant is used for:
Creating redundant CEA-709 network infrastructure
Monitoring a TP/FT-10 channel (ring structure) on cable break
Ensuring communication on the TP/FT-10 channel in case of a single cable break
Monitoring health state of nodes in a CEA-709 network
Determine location of a cable break
Full redundancy with two L-IP Redundant CEA-709/IP Router in parallel for the IP-
Cannel and the CEA-709 channel
Device redundancy by mutual monitoring of paired Redundant L-IPs
Messages and alarming via SNVTs and LonMark-Alarming via Node Object

L-IP User Manual 16 LOYTEC
Version 6.1 LOYTEC electronics GmbH
2 What’s New in L-IP
2.1 New in L-IP 6.1.0
This section describes the major changes and new features. For a full list of changes refer to
the Readme file.
New L-IP Models
The new L-IP models with their product code ending in “C” are now supported. Equipped
with dual Ethernet, a built-in firewall and LCD display, these new models serve as a plug-in
replacement for the older series “B” devices. Existing device backups can be used without
modification. In addition, the new models also support the wireless LAN technology.
Project Documentation
A new feature on the device is a Web UI for creating and viewing project documentation on
the device. The documentation editor requires admin rights and allows storing files on the
device or creating documentation links as URLs. Both items can be viewed by guest users.
Examples include storing cabling plans as PDF or adding links to a Web site containing
manuals, plans or other useful project documentation. Read Section 6.2.17 to learn more
about project documentation on the device.
Dual-Ethernet with Separate Networks
Series “C” L-IP models with two Ethernet interfaces can be configured to work with
separate and isolated IP networks. For example, one Ethernet interface can be accessed over
HTTPS from a WAN connected to Ethernet 2 while the building network services are
running locally on the LAN connected to Ethernet 1. For configuration the device provides
separate Ethernet tabs in the port configuration, which allow selecting the offered services
on each interface. The example in Figure 3 shows a WAN interface with HTTPS and OPC
UA only, while CEA-709 over IP (CEA-852) are still bound to Ethernet 1 (LAN). For more
information on how to use multiple Ethernet ports please refer to Section 6.2.5.

WLAN Interface
In combination with the external LWLAN-800 interface, the device provides new interface
tabs for wireless IP networks. Similar to the second Ethernet interface, one can choose
which protocols are available on the wireless network. The wireless interface can be
configured as a WLAN client, access point or mesh node. Using the latter, a wireless mesh
network of LOYTEC devices can be built. Please refer to Section 6.2.7 to learn more about
the WLAN interface.
SNMP
For accessing vital operational data in standard IT equipment, L-IP series “C” devices offer
an SNMP management base (MIB). All system registers are available in that MIB. The
MIB file can be downloaded from the device and imported in the SNMP management tool.
For more information on configuring and using SNMP with a LOYTEC device please refer
to Section 10.1.
OPC Server
The L-IP series “C” devices are equipped with an OPC server, which can speak the well-
known OPC XML-DA and OPC UA protocols. The OPC server is used for perfect
integration with the LWEB-900 building management software for device maintenance.
Wireshark Packet Capture
The L-IP series “C” models have the Wireshark packet capture feature. Using this feature
local packet logs can be made and stored on the L-IP. It is also possible to connect a
running Wireshark protocol analyzer on the PC to the L-IP and run a life packet capture.
For more information on how to set up packet capture, please refer to Section 13.9.
