IP has to be within the Start IP – End IP range.
Shaping*
List box: On, Off
Default = Off
Ethernet interface could easily overload the Radio channel. Because of that, it is possible to shape
traffic received from the ETH interface.
If
On , specified volume of Data [Bytes] in specified Period [s] is allowed to enter the RipEX from ETH
interface. The first packet which exceeds the limit is stored in the buffer and transmitted when new
Period starts. Further over-limit packets are discarded.
Speed
List box: Auto, 100baseTX/Full, 100baseTX/Half, 10baseT/Full, 10baseT/Half
Default = Auto
Communication speed on the Ethernet interface.
Modbus TCP*
Use this setttings only for Modbus TCP Master when it communicates with both types of Modbus
slaves using either Modbus RTU or Modbus TCP protocols. Or when TCP/IP communication should
run locally between Modbus Master and RipEX in Modbus TCP network. Read Help and Application
note Modbus in RipEX.
For more information refer to the manual Application note / Modbus TCP

.
** - denotes items to be used only when either all or some RTUs (Remote Telemetry Unit) on remote
