3.3.1.3.1.3. IOLITE-GATE: RJ45: Pinout 
 The   IOLITE-GATE   module   includes   four   RJ45  connectors  that  enable  data  transfer  and  synchronization 
 via dual EtherCAT bus. 
 The  same  connectors  are  used  on  Primary  bus  (BUS  1)  for  buffered  data  and  on  Secondary  bus  (BUS  2) 
 for unbuffered data. 
 Each RJ45 connector has two LEDs: 
 -  GREEN  LED  indicates  that  IOLITE  is  connected  to  another  device  (Dewesoft  EtherCAT  device,  PC  or  3rd 
 party control master). 
 -  YELLOW  LED is active only when the data transfer  is active. 
 Connector used on the device is a standard Ethernet connector (RJ45). 
 Standard ethernet cable with standard connector can be used to connect IOLITE-GATE with a PC.
