Status LEDs
The LED labeled "EtherCAT Run" indicates the state of the EtherCAT ASIC. The "Out2" and "Out1" LEDs
indicate the physical state of the Ethernet ports to which they are allocated.

Function
The Extender Module changes the transmitting physics of LVDS (E-Bus) on a twisted pair. The Module is
usually arranged at the end of the block (but this not required). In addition, the Extender Module can be
used in an arbitrary place behind the bus coupler. Thus EtherCAT Slaves can also be connected in star
topology. Standard hubs and switches are not recommended to be used for the EtherCAT network. If you
need to have a star topology, it is recommended to use the Extender module.
CAUTION: Always use the appropriate XML file to review for the EtherCAT
configuration.
The Extender 2-port Module has four ports. The name 2-port Module was chosen because of the two
standard, 100 base TX (OUT1, OUT2) RJ45 connections. Another two ports are covered by the E-Bus.
