5.2.4 Extender 2 Port
Kuhnke's FIO Extender lets you extend a Kuhnke FIO block or a Kuhnke FIO Control
(Embedded PC) by EtherCAT slaves equipped with a standard 100 Base Tx connection.
The extender converts the physical transfer technology from LVDS (E-bus) to twisted pair.
The module is normally located at the end of the block.
You may also place the extender at any point after the bus coupler or the FIO Control
module, though,
to design a star topology of EtherCAT slaves, for example.
