NE-4120S, NE-4120A, NE-4120-ST
The NE-4120S is an RS-232-to-Ethernet server, and the NE-4120A is an RS-422/485-to-Ethernet
server. Both models use pin headers instead of RJ45 connectors. The NE-4120-ST is the
evaluation board for testing NE-4120S and NE-4120A modules and developing your own
applications.
ATTENTION
The NE-4120-ST is the same board as the NE-4110-ST but with an RJ45 jack and pin headers. If
your evaluation board has “NE-4110-ST” printed on the board but has the RJ45 jack and pin
headers, you have the NE-4120-ST board.
