[LNX-204/LNX-204e] LAN Multiplexer 4:1
Enable to switch multi ports from a distant place via
Ethernet or an external contact point.
Overview
LNX-204/LNX-204e is a LAN multiplexer to switch 4 channel LAN port. The function of switching PoE ON/OFF is not supported. All 8-wires are switched physically by the following three ways: send simple command from PC via LAN, input control signal from an external contact point or change switches on the product itself.
A multiplexer IC specialized for LAN is used in the switching circuit. This is very useful to switch external network to internal network, and to connect with the network only when required. It can promote labor-saving for inspection process and auto-inspection system of LAN devices.
LNX-204 supports PoE. That makes it possible to be powered via a LAN cable (PoE compatible HUB or other is required). It can also be powered by the AC adapter.
Network setting can be saved to and restored from a microSD card. Restoring the setting information from a microSD card is very convenient when replacing LNX-204.
LNX-204e is an economy edition of LNX-204 that removes PoE function and an external contact connector.

Features
- Switch Ethernet wires by multiplexer IC
no need to insert and pull out the cable - Switch a port from a distance via Ethernet and or an external contact point
Swich a port via a virtual COM port is also available by using our original application, LNX-VCP - Switch a port manually by changing switch of the product body
- Because unconnected port is not connected, it's possible to use it as a simple firewall
- Easy configuration by microSD
- Easy to restore the setting data at the time of replacement
- Easy to send the setting data by e-mail
- No restriction for IP address setting, out of the network segment
- Easy to backup the setting data
- Configuration via Ethernet is also available by using original setting tool
- Power for the main body supports PoE, powered via LAN cable
switching port does not support PoE

LNX Setting Tool
Using this application, you can easily to make a configuration data of the LNX series.
After saving the configuration data to the microSD card, please insert it to the product. Then the setting data, WR_DATA.TXT, will be read automatically when the product is powered on. At that time, the read data is backup in the microSD card as RD_DATA.TXT.
The setting data is stored in the product. No need to indsert the microSD card next time.
When replacing LNX series, just insert the same microSD card then you could restore the same setting.
When your PC is in the same segment as LNX series, you can also control the setting via ethernet.
