WRM-TS

WRM-TS

WRM-TS 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. This telegram can be read through both the PC interface and/or the M-Bus interface by an external controller. It is ideal for mixed-type networks (wired and wireless M-Bus) because it can read wireless devices and send needed data through the standard M-Bus interface. Supports Primary addressing of attached devices from 1 to 250 (defined by user), but a total of 450/480 devices. Devices above address 250 can be read only by secondary addressing. AES-128 encryption individual keys can be saved for each meter separately, or one key for all.
