The Display Module is shipped with a 3-meter (10 ft) long, shielded
4-pair cable that provides power and serial communications between
the Master Module and the Display Module. The Display Module fits
into a standard ANSI four inch analog meter cutout for panel
mounting. Only one Display Module may be connected to a Master
Module, although you may use one Display Module to configure and
monitor any number of Master Modules; one at a time.
