What is the purpose of the distribution box (connection block) added to some instruments that communicate with Sitrad, available for purchase?

The connection block, also known as the distribution box, has internal protection that reduces the noise coming from engines, electrical cabling, power oscillations, and others, apart from linking the controllers to create the communications network.  The connection block is added, for example, to the following models: MT512E Log, TC900E Log, PCT410E plus, VX1025E, VX1050E e RCK862. It can also be purchased as an independent unit in your preferred retailer.
