The MDS SD Series are industrial wireless solutions that provide long distance communications over licensed radio bands, allowing users to interface to both Ethernet and serial devices such PLCs, RTUs and meters with host monitoring and control systems. The SD’s Media Access Control (MAC) is optimized to reduce Ethernet overhead and preserve bandwidth for higher usable data speed. The IP Payload feature removes unneeded Ethernet frames to shrink messages and improve throughput. MDS SD Series radios can be directly added to existing MDS x710 and x790 systems, providing both "drop-in" compatibility for expansions and replacements, and adding Ethernet support.
