Device family
The 500FSD series out of the EDS500 product family is a product series of ruggedized FSK-
based analog modems. It is especially designed to support critical infrastructure companies
by enabling communication for traditional serial devices like RTUs or IEDs. The 500FSD
product series interoperates with any standard FSK-based technology but is also capable
to achieve higher data rates by enhanced technology. The devices are used in a variety of
markets which require the need for cost-efficient reliable communication.
The following table shows the technical features of the FSK modems.
