Free Serial-TCP (More Than Just A Device Server)
-
In the past two decades, legacy serial communication protocols such as Modbus have merged rapidly with modern TCP/IP communication, yielding benefits including widely available infrastructures and greater distance, reliability, and speed. The Serial-TCP program (more than just a Device Server) bridges your existing Serial COM port and TCP/IP without the need for changing existing protocol. It works seamlessly and transparently, just like passive RS232 / RS485 / RS422 converters, repeaters, and hubs, while the difference is that one requires installation of cables and converters with limited distance; and the other simply makes use of the existing computers and networks with an unlimited transmission distance

MACC

When designing or upgrading avionics systems we are often faced with the task of integrating components that were not originally designed to work together.A control computer that communicates using RS-232 may need to control component that expects MIL-STD-1553 messages or an INS may put out ARINC-429 labels, which are needed by Multi function Display designed around RS-422.Faced with problems like these, integrators must choose between two poor options. They must either give up on one of the units in favor of another unit that may be less suitable but uses the appropriate communications spec; or they must add a computer system – often PC104 – which can translate from one unit to the other. These computers are generally large, heavy, hot, and require substantial power.
