Designed for forming CPS branches, as well as for maintaining the parameters of data exchange signals between counting points and counting and solving equipment within specified limits. Byte-by-byte translation (reception-transmission) of information via RS-485 protocol from one communication line (LS) to another and back.
In this case, the data LS form a single channel, in the "gap" of which the NRT repeater is included. The product restores the electrical characteristics of the signal to the values sufficient for further transmission over the LS in accordance with the specified protocol.
The device performs the described broadcasting through two separate channels in both directions.
The device is placed in a cable socket, track box or transformer box. When receiving a data byte from one LS, the product transmits it to the other LS of the same channel.
No data processing is performed. Communication lines and power supply lines from an external source are connected to the NRT by means of the "Line" connector on the NRT housing.
