The advantage of the rayleighconnect™ EX20 is that when it is connected to any device with a pulse output or RS485 Modbus, it will then transmit the collected data directly to our servers via an Ethernet connection. This is done at a selectable frequency that ranges from once per minute to once per month. The EX20 allows 16 concurrent Modbus/RS485 devices.

The rayleighconnect™ software has been designed to work with any brand of meter, by simply reading the meters registers we can ensure other meters are added to our expanding list and make them compatible with our software.
