Serial communication solutions

Did you know that the RD-48 is a problem solving device for old RS-485/422 communications?

Old bus technologies using RS-485 and RS-422 have strict rules on how the network can be built and used. For instance, a bus network cannot have greater distance than 1200 meters and not more than 32 devices connected to it, or proper functionality is not guaranteed. A bus network also requires the start and the end devices to be terminated correctly, making it impossible to create star topologies.

The Westermo RD-48 repeater is a problem solving device for this type of serial communication as it will allow for greater distances as well as increasing the number of devices that can be connected to the bus. The RD-48 also makes it possible to create star topologies as it can properly terminate multiple bus connections. Using the RD-48 will also add to the overall network robustness as it provides galvanic isolation for each copper cable connection, resulting in a more reliable exchange of data even in environments with high levels of electromagnetic interference.
