limits the network is only as effective as its reach - still unbalanced signals like USB and RS-232 can reliably transmit only up to 15 feet, well balanced Ethernet signals are limited to 300 feet. With a growing range of connectivity platforms, modern data networks not only require compatibility and reliability, but also flexibility and expandability. There are many ideal solutions to meet the distance requirements of modern data networks' such as converting unbalanced signals to balanced ones, the distribution repeaters to boost the signal strength, and the hub for the Star-configured connections implementation, while leveraging fully cost-effective and readily available copper wire. For large systems that go far beyond what the copper wires can reach, fiber optic converters can be used to work both conventional point-to-point and daisy-chain configurations / redundant-ring advanced, giving your data network a push in the distance, ranging from 3 miles to hundreds of miles, and greater flexibility, reliability, and expandability. The use of a serial-TCP program is another ideal solution for combining serial communication protocols with modern TCP / IP communication, obtaining advantages such widely available infrastructure and greater distance, reliability and speed.
Point to Point
Mainly used for one-to-one unbalanced signal (RS-232 , TTL and USB, etc.) extension, it can also be used for the extension of the one-to-one optical fiber. It depends on the type of signal, the extended distance is 250 feet (70 m) to 4,000 feet (1.2 kilometers) of copper wire and 3 miles (5 km) to 40 miles (25 km) of optical fiber.
chain (Multi-Drop)
Typically used for multi-drop RS-485 / RS-422 networks, from Master addressable commands can be sent to all slaves , and the addressed slave can respond to the Master through the same cables, thus reducing the system costs. The typical distance of a daisy-chained RS-485 / RS-422 is 4000 feet (1.2 km), and / RS-422 repeater RS-485, this distance may be extended by 4,000 feet (1.2 km).
Stella harness
Due to the nature of the signals and the need for impedance matching, l '/ RS-422, RS-485 network must run on a linear , daisy chains (multi-drop) configuration; However, star-wiring is inevitable in many places. With hubs very well designed, the wiring in star configuration is not only possible; It makes much more robust and reliable system.
Redundant Ring
data networks are critical to the production, safety and the exchange of information, system downtime is very expensive - and even deadly in some situations. With a self-healing redundant additional connection, a system does not break down even if there is a breaking point in the system, as these redundant-ring networks work in both clockwise and counterclockwise. If the link is down in a clockwise direction, the connection counterclockwise will reset the system instantly.
Network
Legacy serial communication protocols such as Modbus merged quickly with the modern TCP communications / IP, obtaining advantages such as widely available infrastructure and a greater distance, reliability and speed. Proper serial-TCP program offers ideal solutions for bridging your serial port COM / existing and TCP / IP without the need to change the protocol. It works perfectly and transparently, just like a pair of passive repeaters; In addition, instead of requiring the installation of cables and converters with limited space, simply it makes use of computers and existing networks with unlimited transmission distance.
