Long Distance Signal Extension with Multiple Technologies in the Home

The modern home is becoming a technology hub with devices in constant communication across multiple rooms. Centralised signal management has become a large part of the home technology experience. As more devices are added, further away from this central location, cost-efficient and versatile extenders become necessary. This scenario explores the use of four differing extension technologies from Lindy, including powerful fibre optic extenders, to distribute signals up to 300m in residential environments.

Modern residential buildings often feature multiple displays and media sources that use a variety of media signals to transmit audio and video across longer distances as annex or out-buildings become more popular.

In this example four sources are controlled and distributed by a central matrix around a home and to an out-building. The four sources are connected via HDMI cables to a local 4×4 Matrix Pro which then outputs the four signals using different transmission methods for signal extension over a variety of distances. This matrix supports 4K 18G inputs and outputs to ensure that, if the source permits, the entire solution can utilise the full 18G bandwidth capacity of the latest HDMI standards.

In this scenario the matrix outputs to four different transmission technologies. The first, and simplest, of these is a standard local HDMI cable that is provides the 4K connection directly over short distances to a local display. Using audio extraction, the audio signal is first routed to an amplifier before the TV so that a speaker system may be used inplace of the TV’s integrated speakers.

The second output from the matrix is transmitted via an 18G active HDMI cable to a room close to the location of the matrix. The third output passes through a 100m HDMI over CATX extender system. The transmitter unit is connected to the matrix by a simple HDMI cable before the signal is sent along inexpensive CATX cable to the receiver unit which is upstairs/some  distance from the matrix. This receiver is placed close to another 4K display which the signal is finally sent to via HDMI cable.

The fourth, and final, output from the matrix is sent to an out-building, annex, pool area etc. via a fibre optic extender system that features both transmitter and receiver units. By using fibre optic cables to make this connection, large distances up to 300m can be covered using cheap, efficient and easy-to-install duplex fibre optic cabling. This method of signal transmission benefits from EMI & RF resistance so that other electrical cables or equipment located nearby don’t cause artefacts or errors in the transmission. The fibre optic connection allows IR signals to be sent to the display for remote control of the source while also delivering the full 18G bandwidth with no compression, ensuring content arrives at the display exactly how it left the source.

LINDY USB 3.0 to VGA Adapter For The Connection That Just Keeps On Going

It’s been around since the late 80s, but VGA still shows no sign of disappearing

VGA connections might not be as common today as a few years ago, but there are enough old style monitors still hard at work in offices up and down the country to make the new USB 3.0 to VGA Adapter from LINDY Electronics an essential part of any road warrior’s connection kit.

Unlike previous adapters that carried out the processing inside the device, acting as an external graphics card, the LINDY USB 3.0 to VGA Adapter uses the computer’s processer to create the conversion. This not only makes it much more compact than before, but less expensive too.

Bus powered, all it needs to work is for the driver to be installed on the notebook and the adapter connected, making it a simple solution to unpredictable monitor connection situations and an easier alternative to installing a graphic card when a more permanent connection to a VGA screen is required.

“Despite the predicted demise of VGA as it is gradually replaced by HDMI and DisplayPort connections, there is still a vast number of screens in use that have VGA connection,” says Tony Jamieson, General Manager of LINDY Australia. “Whilst notebooks and ultrabooks have dropped the VGA connection, other newer products such as Intel’s half NUC has a VGA port. Whether it will eventually be manufactured with one is probably debatable, but the fact that it’s included at the moment shows the significant number of people that still use VGA.”

The LINDY USB 3.0 to VGA Adapter enables screens to be used as primary, mirrored or extended desktop, enabling a more flexible and productive work environment. Compatible with Windows 7 and 8, the adapter requires an Intel i series 3rd Generation (or higher) processor and supports resolutions up to 1080p.

Adapter converts legacy equipment to work with HDMI displays

We announced today our latest adapter that brings new life to older computers and audio-visual equipment by enabling them to be easily and cost effectively connected to HDMI displays.

The LINDY VGA and Audio to HDMI Converter Adapter comprises of individual VGA, 3.5mm audio and USB (for power only) input cables that integrated into the main housing, which contains the HDMI port.  The adapter converts and combines the VGA and analogue audio signals into a single HDMI output. All the user needs to do is connect it to the legacy equipment and use an HDMI cable to connect the adapter to the newer display.

“In the past VGA and audio to HDMI converters have not only consisted of a bulky box that requires a separate power supply, but they have cost considerably more too,” says Tony Jamieson, General Manager of LINDY Australia. “Our latest adapter offers users a quick and relatively inexpensive way to make use of older equipment such as watching Netflix on their HDMI screen through an old laptop.”

The adapter is a simple plug and play installation and no configuration is required, the output resolution will match the input resolution and supports up to 1080p.
