LNX-003M is a LAN converter which makes it possible to use Modbus RTU/ASCII devices via Ethernet local area network. LNX-003Me is an economy model of LNX-003M which only PoE function is removed.
LNX-003M has obtained the CE marking.(except for PoE function)CE
LNX-003M

Overview

LNX-003M can convert protocols from Modbus TCP to Modbus RTU/ASCII. LNX-003M can connect Modbus devices over Ethernet by acting as masters or slaves. Although Modbus can be used for both serial and Ethernet devices, protocol conversions are also required to interconnect, because not only the physical connection of serial and Ethernet communications, but also the protocol is different. LNX-003M allows you to integrate Modbus TCP and Modbus RTU/ASCII networking.

You can use Lantronix Com Port Redirector (CPR) of the software that maps Virtual COM ports on a PC platform. It redirects application data destined to an attached device via the PC’s local serial (COM) port. Rather than going out the local port, the data is transmitted across the Ethernet network using TCP/IP. LNX-003e attached to the network receives the data and transfers it from its own serial port to the attached equipment.

LNX-003M 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. LNX-003Me is an economy model of LNX-003M from which only PoE function is removed. It requires AC adapter for power supply.
Network setting can be set by a microSD card. Restoring the setting information from a microSD card is very convenient when replacing LNX-003M.

Connection example

[LNX-003M Slave Mode]

LNX-003M
You can control remote Modbus RTU/ASCII slave devices via Ethernet.If the master is a PC, the IP address assigned to the LNX-003M can also be used by assigning it to the virtual COM port.

[LNX-003M Master Mode]

LNX-003M
Modbus RTU/ASCII master device can communicate with remote Modbus TCP slave device via Ethernet

[Tunneling mode between two LNX-003M]

LNX-003M
Direct communication between the two LNX-003M without PCs offers you to connect separated a RS-485 networks. By using cross cable, one to one connection is also available.
