We were an “Internet of Things” (IoT) company before there was an acronym for it. We speak Modbus, DNP3, and a multitude of other weird and off-the-wall protocols. The point is that we can get your old-school serial-protocol-speaking device all cloud-enabled and Big Data-ready.
There’s no secret and it does take a small bit of hardware to help. But it is wayyyy cheaper than buying Ethernet-enabled versions of all your old hardware. In some cases, it may be millions of dollars cheaper.
