2 General
The introduction of UMB technology has enabled Lufft to offer low cost sensors for
road traffic technology. UMB sensors can be combined using ISOCON modules and
additional analog sensors can be integrated with the ANACON module.
The LCom - Lufft Communicator –was developed to provide the UMB sensor data
over various communication protocols.
LCom consists of an embedded computer with Windows CE operating system, a
touchscreen display (resolution 800x480 pixels and CFL backlighting), and interfaces
for a GPRS modem, Party-Line modem and UMB network as well as an Ethernet and
USB interface. In addition, LCom has a real-time clock with battery backup.
Currently following protocols are supported:
•TLS97
•TLS2002
•TLS2012
•TLS over IP (Asfinag)
•NTCIP (via SNMP)
•MSSI (SOAP) (Lufft/Asfinag)
In TLS mode, LCom operates as an “integrated control module with EAK”(Inselbus),
or as “EAK on external control module” (Lokalbus).
Additional protocols planned are:
•DGT (Spain)

3 Hardware Description
LCom Connector
3.1 Power Supply
LCom is powered via UB+/GND (CON220-1) on the UMB-EAK. The allowed voltage
range is 10VDC to 28VDC. The input is protected against reverse polarity, surge and
burst.
Power supply for the GPRS modem (GUB_2/GND) and Party-Line modem
(GUB_3/GND) are provided on connector CON220-1. Depending on the status of the
modem, LCom can switch these two voltages on and off to reset the respective
modem.
The power supply for the UMB network (GUB1/GND) is available on CON220-1. The
maximum output current is 4 amp. If higher currents are required, the sensor heater
tapes must be powered and protected separately.
All output voltages are short-cut proof.
3.2 Operation
The standard functions of the LCom can conveniently be used via the touch screen
display. For configuration purposes we recommend the connection of a PC keyboard
with USB connection, or connecting a PC/Laptop via LAN and using the service
program.

5 Software Description
5.1 Installation
The following files must be copied to the \FFSDISK directory:
LCom.exe –the LCom application
Text_de.uni –the text modules for the user interface in German
Text_en.uni –the text modules for the user interface in English
The following are also absolutely essential for NTCIP:
Snmpapi.dll –the library for all SNMP functions
Snmp.dll –the “master” SNMP agent (Microsoft)
Snmp_hostmib.dll –the SNMP agent for “host” functions (Microsoft)
Snmp_mibii.dll –the SNMP agent for “MIB-II” functions (Microsoft)
Ftpd.dll –the FTP server (Microsoft)
SnmpNtcipAgent_Vx.x.dll –the SNMP agent for NTCIP functions (Lufft)
The “Start.cmd” file must be copied to the \FFSDISK\Startup directory.
This command file copies the “LCom.exe” file from the \FFSDISK directory to “\” (i.e.
to the RAM drive) and starts the application from there. This allows the file
“\FFSDISK\LCom.exe” to be overwritten by an update when necessary while the
system is running.

5.2 Getting Started
The LCom can be operated using only the touch screen display and the virtual
keyboard, but for ease of use it is recommended to connect an USB keyboard to the
LCom, or use a PC and the service program.
We recommend that you attach a small USB hub with keyboard and mouse –so you
can also attach an USB stick to copy files to (e.g. configuration and program files)
and from (e.g. log files) the LCom.
When the LCom starts up, certain registry entries are checked and set if necessary.
The system restarts if any changes are required.
Note: A user name and password are required for access to the system via Telnet, or
for access to all configuration dialogs on the LCom:
User name: lufft
Password: lufft-lcom
Some settings via the Windows CE control panel also require this password.
After this, the application checks whether a UMB device configuration is available or
not. The UMB device configuration is stored in the “device_data.txt” and
“sensor_data.txt” files.
The UMB bus is scanned automatically if no device configuration is available.
The sensor configuration must then be customized to your needs.
The appropriate UMB channels must be activated, and the configuration values for
the uplink protocol (see below) must be set if applicable (e.g. for TLS the FG, Type
and Channel settings, for MSSI the type and channel settings).
The sensor configuration is maintained in the “Sensor Config” dialog. Like all other
configuration dialogs, this dialog is user name and password protected (see “User
Interface”).

Note: If you want to set up several LCOMs with an identical sensor configuration, you
can use the "device_data.txt” and “sensor_data.txt” files to transfer this configuration
to other devices. In this case it is best to install these files in the \FFSDISK directory
before starting LCom. The TLS and MSSI configuration data for the sensors is also
stored in the “sensor_data.txt” file.
5.3 User Interface
Only the first two dialogs, “Status Display” and “Log File”, are generally available. A
user name and password is required for all other dialogs.
User name: lufft
Password: lufft-lcom
The user is “logged out” if the screensaver is enabled.
Note: the screensaver function in LCom disables the LCD backlight after a
configurable amount of time without user interaction (see System Dialog). The
backlight is re-enabled (switched on) if the touch screen is touched, or a mouse
button is pressed.
As it may happen that the backlight does not start properly when it is re-enabled, the
backlight is reset (switched off and on again) if the touch screen (or the mouse
button) is continuously pressed for more than 5 seconds.

5.4 Status Display
This dialog is displayed as the default. The status of the active sensors, including the
most recent measurements, is displayed together with the general system status
(UMB and Uplink communication).
If a sensor value is converted by scaling or value mapping (see below), the
calculated value and the original value (in brackets) are shown.
If a range violation for a TLS data type is detected for a value, the value is highlighted
in red (the corresponding DE error status is then reported for the sensor).
If the UMB device reports an error value for a sensor channel, the UMB error code is
displayed in the “Value” column, highlighted in red. If an UMB device does not report
a value for a sensor channel at all (e.g. because the device does not respond) the
complete sensor data line is highlighted in red.

5.5 Log File
By clicking the “Refresh” button, the last 200 entries in the error log are displayed.
Save to Disk/USB: saves the error log file(s) to the internal “nonvolatile” memory (e.g.
for error analysis). If an USB stick is present, the file(s) can be saved to the USB stick
as well

5.6 Sensor Configuration
This dialog displays all channels of the attached UMB devices. Inactive channels are
shown in gray, active channels in black.
Active channels are displayed at the top of the list.
After starting the application for the first time it may take some time for the system to
read the configuration of all UMB devices. You can update the display by clicking
“Edit Sensor” if no sensor is displayed in this dialog.
To edit the configuration of a channel/sensor, highlight the corresponding entry on
the list and click “Edit Sensor”. Alternatively you can double-click on the entry.
