2. INTRODUCTION
Congratulations on purchasing the HDMOD-5L. You now own a high quality, “Home”
DVB-T HD modulator with Bluetooth interface. To get the most out of your purchase,
please take the time to carefully read through this manual.
3. DESCRIPTION
The HDMOD-5L is a high-quality DVB-T "Home" modulator with HDMI loop-through
circuit. It receives one HDMI as input and converts it into one RF DVB-T channel output
as well as in HDMI out. The excellent picture (Full HD 1920*1080-30p) and modulation
quality (MER~35dB) renders the HDMOD-5L an ideal solution for distributing SD/HD
digital signals received from any device (e.g. a DVD player, STB or camera) in a CATV
network using the DVB-T technology.
The user has the ability to control the device remotely using a Bluetooth interface by
downloading and using the appropriate application from Google play or IOS App
Store for free.
Finally, the HDMOD-5L’s small size and metal case provides excellent electromagnetic
shielding as well as great temperature dissipation and rigidness.

4. INSTRUCTIONS
4.1 - App installation
The HDMOD-5L can be programmed on the field using the following simple steps:
Step 1
Power up the HDMOD-5L, connecting the external power supply. The HDMOD-5L will
need 20-30 seconds to initialize and the status indicator will blink between red and
green until the procedure is finished. After the status indicator remains constantly
green, you will be able to connect to the HDMOD-5L.
Step 2
Download the “Lemco” app from Google play or App Store:
This step is not necessary, if you already have installed the app on your phone / tablet.
Step 3
The app has the following icon:
Upon execution, the app will ask you to turn on Bluetooth. Depending on your phone
/ tablet OS version, you may be prompted also to turn on GPS / Location / Position.
The app does NOT record or use your location. Location services are necessary on
specific Android OS versions for Bluetooth Low Energy (BLE) access.
The HDMOD-5L utilizes BLE (Bluetooth Low Energy) and does NOT need to be “paired”
with your phone / tablet. If you have paired the device with your phone / tablet, please
unpair it.The factory default PIN is 1234.

4.2 - App usage
The app will scan for any available devices that
are within range (Picture No1). The list shows all
detected devices within range, with the device
closest to your phone / tablet at the top of the
list. If your phone / tablet is moved closer to
another device, that device will move at the top
of the list in a few seconds.
Choose the device that you want to connect to,
by tapping on the appropriate “box”. As soon as
the connection between the phone / tablet and
the HDMOD-5L is established, the status indi-
cator on the HDMOD-5L will become red and
you may proceed to 4.4.1.
You may also “connect” to virtual devices shown
as “OFFLINE MODE” to get acquainted with the
menus and features of the app and the devices.
4.3 - App settings
The app has its own settings and features, inde-
pendent of any device. The app features menu
shows up when tapping on the icon at
the top right corner of the screen while scanning
(Picture No2).
You may select the app language, you may read
the app information, terms & conditions, access
the app help, backup or restore all stored cus-
tom profiles (4.3.1).
To close the app settings menu, swipe the scan-
ning page to the right or tap on the icon
again.

4.3.1 - Backup & Restore
The app is capable of backing up and/or restor-
ing all the stored custom profiles (4.4.4) for all
the supported device models. This feature is use-
ful in the following cases:
zx w Reinstalling the app
zx w Lost your phone / tablet
zx w Migrating to another phone / tablet
zx w Sharing your custom profiles with another
phone / tablet.
Your phone / tablet has a hardware-embedded
unchangeable unique code. This code is used to
identify the phone / tablet. It cannot be used to
identify the phone / tablet’s owner, phone
number or extract any other personal infor-
mation.
The backup data are stored on Lemco’s servers.
You may backup your data several times. Each
backup has its own timestamp. When restoring
you may select which backup you want to re-
store by its timestamp.
You may also delete all backups. In such case,
all the backup data corresponding to your
phone / tablet’s unique code will be irrevocably
deleted from Lemco’s servers.
4.4 – Device settings
While connected to an HDMOD-5L, the app
constantly observes the Bluetooth signal level
and displays it on the appropriate on-screen in-
dicator. If the level is critically low, the app will
prompt you to move closer to the device.
If the device is powered down or the Bluetooth
connection gets severed, the app will show a
warning and return to scanning for devices.

4.4.1 - PIN
Before accessing the connected device’s set-
tings, you will need to enter a PIN (Picture No4).
This PIN is specific to the HDMOD-5L you have
connected and is not associated with your
phone / tablet.
The factory default PIN is 1234
You may change this PIN using the “ Security
PIN ” menu option (4.4.12). If you change this PIN,
please keep it somewhere safe, preferably
written on a piece of paper or the “9. Notes” sec-
tion on this leaflet.
4.4.2 - Menu
When the app is connected to a device and the
correct PIN is entered, the device’s main menu
will be displayed (Picture No5).
The main menu consists of the following options:
zx w Quick Settings (4.4.3)
zx w Custom profiles (4.4.4)
zx w Device name (4.4.5)
zx w DVB-T (4.4.6)
zx w Output attenuator (4.4.7)
zx w Encoder (4.4.8)
zx w Transport Stream (4.4.9)
zx w Other settings
w Factory defaults (4.4.10)
w Security PIN (4.4.11)
w Update firmware (4.4.12)
zx w System info (4.4.13)
zx w Help (4.4.14)
By tapping on the “Back” icon labeled “ Scan ”,
the app disconnects from the HDMOD-5L and
returns to scanning for all devices.

4.4.3 - Quick Settings
With this feature you are able to setup several
HDMOD-5L modulators easily and quickly, one
at a time. All you need is to enter the following
parameters, for each of your modulators:
zx w The output RF channel
zx w Set the output level by adjusting the mod-
ulator’s attenuator
zx w Set the Profile No.
The app applies a suitable predefined profile to
the connected device.
The settings are applied to the connected
HDMOD-5L by tapping on the “ Apply ” button.
This feature may be used with different mod-
ulator models.
Picture No6
How the quick settings profile works
In an installation all the modulators (or Mux in general) need to have different values
of the following settings to avoid conflict in the automated scan of the TV sets:
Program Nam Service ID TS ID
For that reason, the user must always select a unique Profile number in every mod-
ulator starting from Number #1.
E.g. If we want to install three modulators in a CATV network, in the profile option we
will select:
zx w Profile Νο 1for the 1st modulator
m meaning: Program Name = DTV 1
m meaning: Service ID = 1
m meaning: TS ID = 2240
zx w Profile Νο 2for the 2nd modulator
m meaning: Program Name = DTV 2
m meaning: Service ID = 2
m meaning: TS ID = 2241
zx w Profile Νο 3for the 3rd modulator
m meaning: Program Name = DTV 3
m meaning: Service ID = 3
m meaning: TS ID = 2242
As a result, all the above modulators have different values in the above settings.

clone it, rename it or delete it. By tapping on the
“ Apply ” button, all the selected profile’s settings
are applied to the connected HDMOD-5L.
Note: The app supports multiple device models.
Each model has its own custom profile list. You
may not apply a custom profile of a device to a
different device model.
