2.2 Overview of ND-6510
The ND-6510 is the RS-422/RS-485 signal repeater which is used to extend or
to lengthen the network distance. A NuDAM bus can connect up to 128 modules.
The repeater should be used when the numbers of the modules exceed 128. In
addition, the repeater should also be used when the length of a signal bus is
more than 4000 feet.
