1.2 MULTIPOINT DIGITAL LINKS (MDL)
The Mimomax MDL is a highly reliable and robust point-to-multipoint wireless linking solution designed for mission-
critical Supervisory Control and Data Acquisition (SCADA) and Telemetry applications. It consists of one or more
Base Radio Units (BRUs) where each BRU supports up to 354 active Remote Radio Units (RRUs) with largest
settable RRU ID of 356. An exception to it is 4.6.x series which were limited to support up to 135 RRUs while still
maintaining IDs settable between 3 and 356.
The Mimomax MDL supports both native IP and legacy Asynchronous Serial RS232 Remote Terminal Units (RTUs)
by means of optional embedded Terminal Server software. A number of interfaces are available to support various
applications. Additionally, the system is capable of supporting remote outstations simultaneously on different
modulation schemes to accommodate various data rates and link paths.
Very high system gains and good receiver sensitivities mean that it is possible to achieve paths in excess of 100kms
from high radio sites at full speed. Furthermore, any branch of MDL can be extended by using the Mimomax point-
to-point Network Digital Link (NDL) radio communications solution.
