HWg-WLD Relay detects a water leak anywhere along the length of the connected sensing cable (2+2m – 6.5+6.5ft). Water leak or cable disconnection is indicated by activating a relay (NO/NC). The sensor can be connected to a Poseidon unit over the 1-Wire UNI bus (RJ11).
HWg-Juno is an I/O device for IP CCTV integration. You can simply connect digital inputs & relay outputs to your current central IP video management system. HWg-Juno support protocols for seamless integration with most IP Video software packages.
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.
Why you should use the Java for Embedded Systems? Java is a modern object-oriented programming language. Java allows for direct implementation of the analysis and design models. Here is a few Java devlopment tools for Embedded systems.
A full-featured simulator for serious analog designers. Sophisticated, internal models allow you to simulate everything from high-frequency systems to low-power IC designs. Draw on the expansive library of models to create off-the-shelf parts, or create models for new devices. Fully explore the relationships in your design with "what if" scenarios before committing to final implementation.
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.
This article describe how to create programmes working with hardware under Windows one should use API's funntions. Here is a few indispensable functions which you need to establish communication. For example funtions to open and close connection, set the connection parameters and functions used to read or write the information from/into the port.
This article is intended to help the designers sort through the various features available in RS-232 interface products. The main features described are the regulated charge pump, Autoshutdown, RS-232 compatible versus compliant operation, ESD protection, and data rates including Megabaud operation
