It has an optical remote control of the STB set-top box.

Specifications, appearance

The IPTV signal set-top box is made in a plastic case with a square side of 150 mm and a height of 55 mm. The front front rectangular side contains an on-state indicator and a photosensor for remote control. The opposite rear panel contains connectors for connecting devices. The remote control uses 2 AAA batteries. The system reset button to factory settings is located on the side rectangular side. It is protected from accidental pressing by the plastic side of the panel with a small hole for the pusher, with which you can act on the button. SML 282 has the following characteristics:

• Processor – STi7105;
• Operational memory – 256 MB, ROM (Flash) – 128 MB;
• The maximum video resolution is 1080p, at a frame rate of 60 fps;
• Supports common audio and video codecs used by providers;
• Power supply voltage +12 V, current consumption 1.2 A.

Interface ports

The SML 282 set-top box uses the following ports of wired communication channels:

• RJ45 connector – LAN port (Ethernet);
• Optical S/PDIF port;
• USB 2.0;
• HDMI;
• RCA connectors 6 pcs (audio, stereo – 2 pcs.), (RGB video – 3 pcs.), (CVBS video – 1 pcs.);
• Power plug.

Equipment

The accessory set includes:

• Device SML 282;
• Remote control with 2 AAA elements;
• Power adapter AC/DC +12V;
• HDMI cable, 3xRCA, 5xRCA, Ethernet;
• Instruction in Russian, packaging.

Connection and setup

First you need to connect the set-top box to your TV or monitor. To do this, depending on the TV model, it is proposed to use one of 3 options:

1. HDMI – the connectors of the set-top box and the TV are connected by a cable;
2. 3xRCA – 2 audio outputs (red and white or black), 1 video (yellow);
3. 5xRCA – 2 stereo audio and 3 video (RGB).

When properly connected and the corresponding mode is activated on the TV, a high-quality splash screen should appear on the screen. Next, connect the Internet through the LAN connector to the router. When authorizing, they use the login and password received from the provider when concluding the contract.

Set up according to the algorithm from the instructions, then you will need to enter an individual network device code. The MAC address is indicated on the console panel. It can also be found in the “System Information” section after the system is turned on and booted.
 Setting up the SML 282 remote control is carried out according to the instructions. DU from different providers differ.

Official and alternative firmware for Smartlabs SML 282 HD Base

It will not be possible to change the software in Smartlabs SML 282 HD Base using the presented control interface. The system itself requests an update and, if a new version is available, it is updated. However, the printed circuit board of the device contains an RS-232 port, through which the microcontroller program can be flashed in the service center. For this purpose, matching equipment and appropriate software are required.

Please note that the instructions for the firmware cannot be universal. For each brand of device there is a strictly individual algorithm. The firmware process cannot be interrupted, otherwise the device will become inoperable. The firmware of the Rostelecom set-top box SML 282 has an already configured service package from the provider. The Smartlabs SML 282 HD Base set-top box contains firmware with the ability to connect to MTS, Rostelecom or other operators. There are SML 282 HD Base consoles that contain alternative firmware. With such software, it is possible to choose a provider. Do-it-yourself alternative firmware for the Rostelecom set-top box Sml 282 – video instruction: https://youtu.be/I7QNTJ_Chcw

Set-top box cooling

The operation of the processor of the IPTV signal processing device causes the chip chip on which the air cooler is installed to heat up. Therefore, during the operation of the product, it is necessary that the body of the attachment has free access to air, is not wrapped up and the ventilation is not closed.

Problems during operation and their solution

During operation of the set-top box, failures and errors may occur. To solve problems with their appearance, you must first turn off the device and allow time for the microprocessor chip of the product to cool down. If after restarting the failures have not disappeared, then:

1. It is necessary to check the correctness of the connection and the reliability of the contacts on the wired interfaces;
2. Do a factory reset and reconfigure the device.

If the services provided by the provider are not satisfied or the user decides to increase the number of channels or add other features, then to solve such problems, they change the software. At the same time, an alternative android firmware is installed on the SML282 HD Base, for example. It should also be noted that changing the program does not guarantee the operability of the device in the amount provided by the manufacturer of the equipment.

Pros and cons

The Smartlabs SML 282 HD Base has access to the digital resources of the servers. Can be powered by fiber optic cable or wired Ethernet. Its main advantage is interactivity – the ability to manage content with high quality playback. The disadvantage of such devices is the dependence of the owner of the device on the service provider and the subscription fee. But the user is provided with wide possibilities of the device with high confidentiality. Set-top boxes like SML-282 have the ability to turn almost any, even archaic, TV into a Smart TV. An inexpensive device can implement many functions that only computer technology has.
