ISM-usb/m

General information
The IBRit-rf1 and ISM radio module series allow the wireless transmission of measurement data from gauges to a PC with USB interface or to an IMB-rf1 / IMB-ISM module (as the case may be).
On the PC side the wireless communication with the gauges occurs via the ISM-usb PC - Radio station. The ISM-usb PC - Radio station is connected to the PC via a USB port and allows the communication in an address range from 1 ... 500. The differentiation of the data from the individual radio modules is achieved by address numbers. The address number and other individual radio module settings concerning the particular application can be transmitted from the PC to the radio modules and are stored there. The corresponding PC software IBR_SimKey is included in the delivery of the ISM-usb PC - Radio station.
