Signal Converters
-
On one hand, there are signal converters which transform an input frequency range into an analog signal. These signal converters are very easy to program and control. Other signal converters can transform analog input signals into analog normalized signals with galvanic insulation. Due to the fact that these signal converters can be freely graduated, they offer endless possibilities and 110 combinations can be selected by means of a DIP switch. Other kinds of signal converters can be connected to devices with RS-232, RS-485 or RS-422 protocols.

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
