The LIN is a new bus technology which brings a more possibilities. The main field of usability is the vehicle industry. It should be considered as the low-cost alternative to a CAN (Controlled Area Network) bus. The both - CAN and LIN - are usable in several industries not only in the car industry. The low-cost and wide applicability has been the main reason for the LIN development. The LIN bus seems like a good solution and we can expect a big advancement of the technology.

Industrial plants comprise many devices interconnected in different ways: simple data collection units without any built-in intelligence, more intelligent devices such as sensors with built-in intelligence, single-loop controllers or programmable controllers and supervisory systems. Bluetooth wireless technology is potentially useful for all of these.

Power Over Ethernet (PoE) also called Power Over Lan (PoL), is one of existing possibilities how to transport data and supply voltage to Ethernet device by already existing net of cabling CAT5 for computer networks (10 Mbit/s and 100 Mbit/s).This standard, which will probably define the future development of Ethernet devices, was finished and authorized in last year’s June as a standard IEEE802.3af.

ISDN is replacing our old analog phones and offers a lot of new services. It is the easy way how to transmit voice and data simultaneously at the same time using an andvantages of a digital communication. Now I want to explain you, how does it really work.

PS2 connector is in these day present almost in every computer. It is used to connect keyboard or mouse (or some else pointing device). This article contains information about connection, communication (host-to-device and device-to-host) over ps2 port and also about coding of keyboard

Asymmetric digital subscriber line (ADSL) uses existing twisted pair telephone lines to create access paths for high-speed data communications and transmits at speeds up to 8.1Mbps to a subscriber. This article explains the basic function of ADSL transceivers and their modulation scheme.

This document provides an introduction to intelligent modems, the AT command set and the concepts behind many of the commands. The AT commands are used to configure the modem to your preferred operating mode and to instruct the modem to do what you want it to do.

Description of IrDA standards, explanation of MODULATION of infra-red devices (the Pulse Code Modulation, the Frequency Shift Keying-FSK, the Bi- Phase Modulation, The Pulse Width Modulation-PWM) and TRANSFER PROTOCOLS (the RC-5 protocol, the NEC protocol, IrDA). See for more information...

Power-over-Ethernet (PoE) is an emerging new technology that enables delivery of data and power to internet appliances over existing CAT-5 Ethernet cables. PoE is rapidly gaining in popularity with manufacturers and end users of devices such as VoIP phones, wireless access points, security cameras and point-of-sale terminals. PoE is governed by the standards defined in the recently ratified IEEE802.3af standard.

This article describe how USB device indicate its speed. You can find here solutions some vendors and circuits devices with pull up resistor.
