Hardware Use Cases for the Gateway

The N2E hardware has two different Network Interface options, Independent and Switch Mode. Below,
you can find the different use cases that each interface option allows for.

Independent Mode

•

Two Ethernet based protocols on the same IP Network

Ethernet Port 1 Used OR

Ethernet Port 2 Used OR

Ethernet Port 1 & 2 Used

•

Two Ethernet based protocols on different IP Networks

Ethernet Port 1 Used AND

Ethernet Port 2 Used

Switch Mode

–

Only Ethernet Port 1 is used for protocol communication

•

One Ethernet based protocol on the IP Network (layer-2 switch)

Ethernet Port 1 Used for direct protocol communication

Ethernet Port 2 available for Daisy-Chaining devices together

A Ring topology is NOT supported

•

Two Ethernet based protocols on same IP Network

Ethernet Port 1 Used for direct protocol communication with another switch, hub, or
router

Ethernet Port 2 available for a Daisy-Chaining devices together

A Ring topology is NOT supported

•

Two Ethernet based protocol on different IP Networks

Not Possible
