Its network is as effective as its reach - yet unbalanced signals such as USB and RS-232 can reliably transmit only up to 15 feet, and even Ethernet balanced signals are limited to 300 feet. With a growing range of connectivity platforms, modern data networks just do not require compatibility and reliability, but also the flexibility and expandability. There are many ideal solutions to meet the needs distance networks modern data 'as the conversion of signals not balanced, deploying repeaters to increase signal strength, and implementation center wye-configured, while to make the most cost effective and readily available copper wire. For large systems that go far beyond what copper cables can reach the fiber optic converters can be used to work on both conventional point to point and configurations / redundant ring connection in advanced chain, giving its data network a boost in the distance, ranging from 3 miles to hundreds of miles, and greater flexibility, reliability and expandability. Using a series-TCP program is another ideal for melting serial communication protocols with modern communication TCP / IP solution, producing benefits such as infrastructure widely available and greater distance, reliability and speed.
Point by point It is primarily used for one-to-one extension of the unbalanced signal (RS-232, TTL and USB, etc.), also it can be used for one-to-one fiber optic extension. It depends on the types of signal, the extended distance between 250 feet (70 m) to 4000 ft (1.2 km) in the copper wire and 3 miles (5 km) to 40 miles (25 km) into the optical fiber . Daisy Chain (multi-point) Typically used for multipoint RS-485 / RS-422 networks, addressable commands from the Master can be sent to all slaves and the addressed slave can respond to the Master through the same wires, which reduces system costs. The typical distance for a network in RS-485 / RS-422 chain is 4000 feet (1.2 km), and the RS-485 / RS-422 repeater, this distance can be extended by another 4,000 feet (1, 2 km). Star wiring Due to the nature of the signals and impedance matching requirements, the RS-422 / RS-485 network must run in a linear fashion, daisy chain (multi-drop) configuration; However, star-wiring is inevitable in many places. With the axes of good engineering, star-wired configuration is more than possible; which it makes much more robust and reliable system. redundant ring Data networks are critical to production, security and exchange of information, system downtime is very costly - and even deadly in some situations. With a self-healing redundant additional bond, a system will not break, even if there is a breaking point in the system, since these redundant ring networks operate in both clockwise and counterclockwise. If the link clockwise is down, the link anticlockwise the system will recover instantly. Network Legacy serial communication protocols such as Modbus quickly have merged TCP / IP modern communications, producing benefits such as infrastructure widely available and greater distance, reliability and speed. A serial-TCP program suitable offers ideal solutions for bridging the COM / existing and TCP / IP serial port without the need to change the protocol. It works seamlessly and transparently, like a pair of passive repeaters; Moreover, instead of requiring the installation of cables and converters with limited distance, simply it makes use of computers and existing networks with unlimited distance transmission. To achieve any of the 5 Ways up for your travel unlimited data, CommFront has the full range of converters, repeaters, hubs, fiber optics and software solutions to make everything possible.
