How to Configure Ethernet to Serial Converter MOXA NPORT Operation Mode as REVERSE TELNET 

I am using nport 5150 but can't read data binmaster level radar. Can u help how to setting the moxa nport 5150?

I am working on moxa mb3480 coverter, there are 4 devices whose rs 485 terminal are looped and connected to 1 port of moxa converter. It outs data in modbus tcp ip. The problem is that the data after moxa converter is not continuous, its flickering. Whats the solution to make it continuous?
