2. Product Summary
LNX-003 is a LAN converter which makes it possible to use RS-485/422 devices via
Ethernet local area network. RS-485/422 side is isolated and the LAN interface is also
isolated, so LNX-003 consists of double isolation.
Tunneling mode is available by connecting with LNX-001 (USB to LAN converter) or
LNX-003. In that case, connecting with devices in other RS-485/422 network is possible.
And by using TCP/UDP or Telnet, direct control from PC is also available.
LNX-003 supports PoE function as a standard model, making it possible to be powered via
LAN cable (PoE compatible HUB or other is required). It can also be operated from AC
adapter.
Network setting can be set by a microSD card. Restoring the setting information from a
microSD card is very convenient when replacing LNX-003.

7. Connection examples
[Tunneling mode between two LNX-003]
Direct communication between two LNX-003 without PCs offers you to connect separated a
RS-485/422 networks. By using cross cable, one to one connection is also available.
[Tunneling mode between LNX-001 and LNX-003]
LNX-001 offers you to control as USB interface via the LAN. By connecting this with LNX-003
in tunneling mode, virtual COM port and D2XX-API by FTDI is available.
Technical knowledge about the network is not needed.
[LNX-003 single operation]
Communication with RS-485/422 devices via Ethernet local area network is available.
* Please use a cross cable to connect LNX-003 without using a hub.
(LNX-003 does not have a function for AutoMDI/MDI-X.)
