3.3.7. Specific interfaces to Serial-Port Models (eWON Flexy 102 & 202)
1 x RJ45 ports switch LAN Ethernet 10/100.
SubD 9 male RS232/422/485 port.
1500V functional galvanic isolation through the power supply isolation from ground.
3.3.7.1. LAN Port
The LAN interface consists of one auto-sense Ethernet port (10/100 Mbps). Auto-sense meaning that
you can use both UTP Class 5 direct and crossed cables with RJ45 terminations at both ends. Default
parameters see §
5.1 Factory Default IP settings.
