L-Proxy User Manual 11 LOYTEC
Version 3.1 LOYTEC electronics GmbH
1 Introduction
1.1 Overview
The L-Proxy is a high performance network infrastructure component for CEA-709
networks. It is the first device that allows network variable bindings across multiple
domains, SNVT translation, address table expansion for CEA-709 nodes, firewall security
etc. The L-Proxy provides five communication ports and it translates packets between
these ports. Available ports are two FT ports, and three IP-852 ports. The three IP-852
ports are connecting to an IP-852 backbone channel. The L-Proxy’s unique architecture
very much supports well defined interfaces between various subsystems like HVAC,
lighting, and security in a typical building. Easy to understand diagnostic LEDs allow
installers and system integrators to install and troubleshoot this device without expert
knowledge and dedicated troubleshooting tools.
The basic operation of L-Proxy is to take an input network variable (NV) or configuration
property (CP) on one side, interpret the data in the variable and transmit a corresponding
output network variable on the other side. This concept is used to solve a great amount of
today’s communication problems in CEA-709 networks as explained in the following
chapters. The device is fully compliant with ANSI/CEA-709, and ANSI/CEA-852-A,
EN 14908.
Network variables (NVs) in the CEA-709 network can also be operated as “external NVs”.
External NVs are polled or explicitly written to without allocating static or dynamic NVs
on the L-Proxy. In this case, address information is supplied by the configuration software
by importing e.g., a CSV file. User-defined network variable types (UNVTs) can be used
as dynamic or external NVs. Configuration properties (CPs) on other devices can be
accessed through file transfer. To transfer CPs, the device supports both the LONMARK file
transfer and the read memory access method. For CPs, the standard SCPTs and user-
defined UCPTs are supported.
L-Proxy is configured over the network with an easy-to-use configuration tool. This
configuration tool can be used as a plug-in for LNS-based network installation tools or as a
standalone tool.
The built-in Web server allows convenient device configuration through a standard Web
browser such as the Internet Explorer or Firefox. The Web interface also provides statistics
information for system installation and network troubleshooting.
The L-Proxy is used for:
•Binding of network variables (NVs) across multiple domains (up to 5 with a single
device),
•mapping configuration properties (CPs) to network variables (NVs),

L-Proxy User Manual 12 LOYTEC
Version 3.1 LOYTEC electronics GmbH
•using static, dynamic, or external (polled) network variables,
•supporting standard (SNVT, SCPT) and user-defined (UNVT, UCPT) types,
•translation between different SNVT types,
•overcoming the 15 destination addresses limit by expanding the address table in
Neuron Chip based network nodes (up to 512 address table entries on each port),
•saving group addresses by breaking up groups into individual NV updates,
•a firewall for CEA-709 networks,
•supporting up to 512 network variables on each port,
•supporting up to 512 alias-network variables on each port,
•supporting up to 512 address table entries on each port,
•browsing data points on the Web interface,
•communicating on CEA-709 with either FT or IP-852 (IP channel on the
Intranet/Internet).
1.2 Scope
This document covers L-Proxy devices with firmware version 3.1 and the L-Proxy
Configurator 3.1 and higher. See Section 14 for differences between the different L-Proxy
firmware versions. For L-Proxy devices with firmware versions before 3.0 please refer to
L-Proxy User Manual version 2.2 [2]. Also note, that firmware and configuration files of
L-Proxy 3.0 and higher are not compatible with 2.2.

2 Quick-Start Guide
This Chapter shows step-by-step instructions on how to configure the L-Proxy for a simple
network architecture, mapping CEA-709 network variables from different ports of the
L-Proxy.
2.1 Hardware Installation
Connect power (12-35 VDC or 12-24 VAC), the CEA-709 network, and the Ethernet cable
as shown in Figure 1. More detailed instructions are shown in Chapter 3.
Important: Do not connect terminal 17 with Earth-ground!

2.2 Configuration with LNS-based Tools
This section describes a quick start scenario for the L-Proxy. In this scenario network
variables are created on Port 1 (FT) and Port 2 (FT). The two ports can be in different LNS

L-Proxy User Manual 14 LOYTEC
Version 3.1 LOYTEC electronics GmbH
databases and different domains. Then NVs are connected on L-Proxy by creating internal
connections.
First, install the L-Proxy Configurator Software from the “setup.exe”. This file can be
downloaded from www.loytec.com. In your LNS-based tool, register the L-Proxy
Configurator as LNS plug-in.
Open an LNS database and add an L-Proxy device for Port 1 (FT) using the device
template, which has been created for the L-Proxy (e.g., L-Proxy_V3_0_FT-10.xif). Then
create dynamic NVs on that L-Proxy port, e.g., “nviTemp” and “nvoSwitch”. Close the
LNS database. For detailed information on how to create dynamic NVs in LNS-based tools
refer to Section 7.7.
Open another LNS database and add an L-Proxy device for Port 2 (FT) using the device
template, which has been created for the L-Proxy (e.g., L-Proxy_V3_0_FT-10.xif). Then
create dynamic NVs on that L-Proxy port, which are opposite to the NVs on port 1, e.g.,
“nvoTemp” and “nviSwitch”.
To Create the Internal Connections
1. Open one of the two databases.
2. In LonMaker right-click on the L-Proxy device and select Configure … to launch the
L-Proxy Configurator as plug-in.
3. This opens the data point manager screen of the software as shown in Figure 2. Note
that the device status is displayed as “Configured” on the right-hand side below the
speed button bar.
Figure 2: L-Proxy Configurator plug-in main screen.
4. Click on the Upload Configuration speed button as marked by the red rectangle in
Figure 2.
5. This uploads all dynamic NVs from all ports of the L-Proxy. Figure 3 shows an
example result of the upload.

L-Proxy User Manual 15 LOYTEC
Version 3.1 LOYTEC electronics GmbH
Figure 3: Example result of synced dynamic NVs.
6. Click the magic wand button Auto-create connections for auto-connecting the
NVs. This creates internal connections for the NVs with the same base name. The
prefix “nvi” and “nvo” are ignored. Therefore, two connections are created in our
example, one named “nviTemp”, and one named “nviSwitch”.
7. Click on the Connections tab and view the generated connections as shown in Figure
4.
Figure 4: Generated connections.
8. Click on the Download Configuration button in the tool bar as indicated by the red
rectangle in Figure 4. This opens the configuration download dialog as shown in
Figure 5.

Figure 5: Download the configuration to the L-Proxy.
9. Click on Start to initiate the download process. The dialog shows the currently
executed tasks.
10. Click OK when the download is finished and close the download dialog. It is
recommended to save the L-Proxy project to a disk file.
11. Select File ÆSave As … and enter a suitable file name in the file requestor. The
project file is stored as an ‘.lprxy’ file.
After the configuration process, the NVs from Port 1 and Port 2 are connected over the
internal connections. Any updates on the NVs of the devices connected to Port 1 are then
propagated to Port 2 and vice-versa.

Table 1: CEA-709 Activity LED Patterns
3.4.4 Ethernet Link LED
The Ethernet Link LED lights up green whenever an Ethernet cable is plugged-in and a
physical connection with a switch, hub, or PC can be established.
3.4.5 Ethernet Activity LED
The Ethernet Activity LED lights up green for 6 ms whenever a packet is transmitted or
received or when a collision is detected on the network cable.
3.4.6 CNIP LED
The CNIP LED is a three color LED that indicates different operating states of the
L-Proxy’s CEA-852 device.
Green: The CEA-852 device is fully functional and all CEA-852 configuration data
(channel routing info, channel membership list, send list) are up-to-date.
Green flicker: If a valid CEA-709 packet is received or transmitted over the IP channel the
CNIP LED turns off for 50 ms. Only valid CEA-709 IP packets sent to the IP address of
the L-Proxy can be seen. Stale packets or packets not addressed to the L-Proxy are not
seen.
Yellow: Device is functional but some configuration data is not up-to-date (device cannot
contact configuration server but has configuration data saved in Flash memory)
Red: Device is non-functional because it was rejected from the CEA-852 IP channel or
shut-down itself due to an internal error condition.
Off: Device is non-functional because the CEA-852 device has not started. This can be the
case if the L-Proxy uses DHCP and it has not received a valid IP configuration (address)
from the DHCP server.
Flashing red at 1 Hz: Device is non-functional because the CEA-852 device is started but
has not been configured. Please add the device to a CEA-852 IP channel (register in
configuration server).
Flashing green or orange at 1 Hz: The L-Proxy’s CEA-709 side of the gateway has not
been commissioned yet. The color indicates the CEA-852 IP channel status as described
above.

3.4.7 Config LED
This LED is green, if the L-Proxy is running with a valid proxy configuration.
3.4.8 Wink Action
If the L-Proxy receives a wink command on any of its network ports, it shows a blink
pattern on the CNIP and the CEA-709 activity LEDs. The CEA-709 activity and the CNIP
LED turn green/orange/red (each 0.15 s). This pattern is repeated six times. After that, the
CNIP LED flashes orange six times if the wink command was received on the IP channel
or the CEA-709 activity LED flashes orange six times if the wink command was received
on the CEA-709 channel. After that the L-Proxy LEDs resume their normal behavior.
3.5 Status Button
The L-Proxy is equipped with a status button (see Figure 6). When pressing the status
button shortly during normal operation of the L-Proxy, it sends a “Service Pin Message” on
the active CEA-709 network port (FT or CEA-852). As an alternative to pressing the status
button, a service pin message can be sent via the Web interface (see Section 5.1).
The status button can also be used to switch the device back to factory default state. Press
the service button and power-cycle the device. Keep the button pressed until the port LEDs
illuminate orange permanently. Release the button within five seconds from that time on to
reset the device to factory defaults. Alternatively, the device can be switched back to
factory defaults over the console UI (see Section 4.3.7).
3.6 DIP Switch Settings
The DIP switch assignment for the L-Proxy is shown in Table 2. Please leave all switches
at default state.

3.7 Terminal Layout and Power Supply
The L-Proxy provides screw terminals to connect to the network as well as to the power
supply. The screw terminals can be used for wires of a maximum thickness of
1.5 mm2/AWG12. The device can either be DC or AC powered.
