WRMnano

WRMnano is a wireless m-bus receiver, intended to collect data from various devices, working in modes T, S or C, according to the wireless m-bus standard (EN13757-4).

This device has a simple function – collect data from every wireless meter which is told to, and convert this data to a normal M-Bus telegram. WRMnano has the capability to gather data from up to 64 metres. It can work in automatic mode, where it finds and activates all meters in range. In this mode each meter is saved with an ID and primary address 0 and a maximum of 64 meters can be found. Or the user can set exact ID numbers for readout with our software. The device is powered from wired M-Bus and is 5 standard M-Bus loads (7.5 mA). Powering from standard M-Bus is the main advantage of our concentrator in mixed networks. AES-128 encryption individual keys can be saved for each meter/primary address.
