SMARTKOM INSTALLATION

Install the receiving antennas and point them towards the transmitters to be received.
The receiving antennas must operate in the frequency bands of the television signals used by the local broadcasters in your area.
Consult with your local TV stations or use online resources such as www.rabbitears.info or www.antennaweb.org to check what channels the local TV stations are broadcasting on to determine which frequencies VHF Hi/Low and/or UHF in order to choose the proper antennas.

Example of channel searching using a web application.

Connect antennas to the inputs of SmartKom
It is recommended to install the antennas at the highest possible position on the mast to optimize signal reception, avoiding obstructions, fading or reflections. It is recommended that the coax cable between the output of the antennas and the SmartKom inputs be as short as possible to avoid signal loss to obtain the optimum CNR (signal quality) at the output. SmartKom can be located outdoors (on the mast or other mounting options) using the weatherproof enclosure provided with the device, or indoors keeping in mind the coax cable length. For outdoor use, protect the “F” connectors of the amplifier using the supplied watertight cover to prevent water from entering.

Connect the output of SmartKom to the power supply.
The output of the SmartKom will be connected to the power supply located indoors near a 120V household power outlet. The power supply provides the necessary power for the operation of SmartKom as well as its configuration and control commands via the Bluetooth enabled interface. (See section: ASuite configuration).

SMARTKOM PROGRAMMING

(Note): The inputs and the outputs must be charged for the correct unit adjusting. 5.1 Automatic programming

SmartKom incorporates a channel search, adjustment and balance button.

• Search and Balance: Activated by a long press (>5 seconds, either on the amplifier or on the power supply) and is signaled by a slow flashing of the green LED. SmartKom searches for all existing channels in the inputs and bands in use (VHF low, VHF high and UHF). RF channels below a predetermined signal level are dismissed, preventing unwanted or destructive signals. Subsequently, SmartKom equalizes the output levels of selected channels resulting in a balanced system.
• Adjustment and Balance: Activated by a short press (<3 seconds, both on SmartKom and on the source) and is signaled by a rapid flashing of the green LED. In this case, SmartKom does not carry out a channel search but instead a balancing of the channels that a previous search would have found or that the user had programmed through the ASuite App.
• (Note): The user may have previously programmed the channels (for example, after consulting a database) and later, in the location where the SmartKom is going to be installed, adjusting and balancing after the antenna or antennas are connected to SmartKom.
• (Note): The user may occasionally need to adjust the signals due to changes in propagation conditions, vegetation, seasonal changes, etc.
• This function can also be activated using a smartphone or tablet, with the ASuite app. This app connects via Bluetooth to the device and offers the facility and the comfort of programming the installation from the palm of your hand, without having to physically go up to the SmartKom location.

Advanced programming
SmartKom has the ability to manually adjust and balance channels, through a smartphone or tablet, using the ASuite app (iOS or Android). In order to access the device settings, the smartphone/tablet connects to the power supply via Bluetooth.

ASUITE CONFIGURATION

The use of the ASuite App is recommended for the following reasons:

• Provides a visual confirmation of the output level of all scanned channels.
• User is able to adjust the level of SmartKom to compensate for distribution losses of the coaxial network to avoid excessively strong or weak signal at the TV sets.
• A final fine adjustment can be performed on individual channels as needed.

In addition, the App enables other options, such as reading and loading configurations, importing and exporting configurations, and antenna power control (AUTO/ON/OFF). Once the reference of the device selection is complete the main screen is displayed to enable SmartKom’s Configuration. The screens for iOS and Android are shown as follows:

Figure 8: Main screen Android once the connection with the Smartkom is established
Both in Android or in iOS, the control and configuration of the device is done by using the following interfaces:

1	Connection ASuite- SmartKom	10	Press or scroll to open screen of channel balancing
2	Read SmartKom Configuration	11	Channels found in input 3
3	Send configuration to SmartKom	12	Channels found in input 2
4	Adjusting and balancing of channels	13	Channels found in input 1
5	Activate the autoprogramming function	14	Output level adjusting (dBmV)
6	Save configuration	15	Input 3
7	Open stored configuration	16	Input 2
8	Option menu	17	Input 1
9	Antennas power control

1. Connection ASuite – SmartKom: The connection between ASuite and SmartKom is achieved via the Bluetooth interface enabled in the power supply.
   (Note). Bluetooth interface is enabled once the Power supply is turned on. By default, it is always on but can be disabled to minimize power consumption after a certain time (Settings menu). To re-enable it, it is necessary to power-cycle the unit.
2. Read SmartKom Configuration: ASuite reads the configuration (channels, power, programmed output level) of SmartKom.
3. Send configuration to SmartKom: ASuite sends the configuration chosen by the user (channels, power, programmed output level) to SmartKom.
   (Note). The ASuite configuration changes do not mirror automatically in the SmartKom. The user must send the selected configuration to the device using this button.
4. Adjusting and balancing of channels: The adjustment and balancing of the SmartKom channels is activated. This is equivalent to the “short press (< 3 sec) which is done either in the SmartKom or in the PSU.
5. Activate the Autoprogramming function: SmartKom searches the most prominent channels in each input and filters them. Then adjust and balance the levels of the filtered channels. The entire process takes less than a minute.
6. Save configuration: SmarKom configuration is stored in the memory of the device (Smartphone or similar) which was used to programs it.
7. Open stored configuration: A previously stored configuration may be retrieved from memory.
8. Option menu: Shows all available options in the App.
9. Antennas power control: 3 different power modes can be selected on each input: AUTO/ON/OFF (Note): SmartKom stores the configuration chosen by the user: channels, input power supply, programmed output voltage.
   Please Note; if the user performs a channel search, the configuration will be overidden by the SmartKom, according to the search algorithm, discarding the user’s changes.
   Every time a channel scan is done, the unit will discard the existing configuration. Notice that the algorithm search is optimized and governs three input preamplifiers individually, and automatically makes its decisions about the power control of the antenna or antennas to find the best signal. Therefore, it is recommended to combine the SmartKom with High Dynamic Range Antennas (Such as Televes’ Ellipse or DAT LR series of high performance antennas) for search optimization in any reception scenario
10. Scroll to open screen of channel balancing: When the channel adjust visualization screen is open, the user can double check the final result and fine tune if needed.

(Note): If a programmed channel with a level lower than the SCHEDULED OUTPUT LEVEL is shown on the channel visualization screen, it is most likely that its input level to the SmartKom is less than the input threshold level (-28 dBmV). If the user makes the decision to include it in the channel list manually and makes an adjustment, SmartKom would not be able to adjust it to the scheduled output level and it would be displayed with a lower level.
Such a channel would not be displayed after the user performs an automatic channel search (search and balance button on the SmartKom or on the power supply), since it would be discarded by the search and balance algorithm. In short, once the adjustment and balancing of the unit is completed, any channels that appear in the adjustment screen with a level less than the programmed output level, are indicative of being below the input level required by the unit, and its operation can be potentially marginal. On those weaker channels the user can try additional manual tuning to improve performance or try to optimize the antenna aiming. (adjust antenna left to right and/or up/down)
10,11,12. Channels found in input: Visualization (selection) of channels on different inputs.

In the channel visualization, selected channels (in the figure, input 1) are highlighted in the same color as the input. Those highlighted in gray correspond to channels that are selected in other inputs, while the rest of the channels (in white) are not selected on any input.
Output level adjusting (dBmV): Output level is adjusted starting (maximum 25 dBmV).

Note: Maximum output level is 25 dBmV regardless of the number of channels that are amplified.
14, 15, 16. SmartKom inputs: Reference to the SmartKom connections and controls section.
