The communication unit CU-Bx is used to supplement the ZxDxxxAT/CT meters. It contains an RS485 and an RS232 interface depending on version for remote scanning of the meter and two signal inputs (S0 interfaces) for connecting external signal transmitters.

The RS485 interface can be used for simple remote reading (e.g. together with several meters). The RS232 interface remains free for local use or serves for the connection of an external communication device (e.g. modem).

With version CU-Bx/+ the RS232 interface provides additional functions, such as time-window or initializing of the external modem.
