Expected TCP traffic and LED indications

SEM3 Controller is intended to be used in a secured network, when external data is needed it is recommended to use a data logging device or to utilize a port forward inside of a secure network to prevent unwelcomed traffic to the SEM3 controller.

Data logging devices in a local network can be used to expose data to an external network. Typically, they are a read only device that allows one-way communications.

A Port forward is a function found in most routers that allows routing traffic with an external IP address and external port to an internal IP address and port. Please refer to your router’s user guide on how to perform a port forward.
