2. Product Summary
LNX-205 is a LAN multiplexer to switch 2 LAN ports of 2 individual channels.
LNX-205 can change the LAN port by three ways: send simple command from PC
via LAN, input control signal from an external no-voltage contact (dry contact) or
change switches of the product body. 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-205 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-
205.

with GND, the LAN port is switched.
e.g. Short LAN B1 (pin no. 3) with GND (pin no.5): channel B common port (B
COM) and channel B switching port (B1) is connected.
* #4-40 UNC screws are mounted by factory setting. You can change them to attached
M2.6 screws.
* COM A (pin No.7), COM B (pin No.9) is an option for DC 5V to 24V power input.
If you need to change LAN port directly from open collector or transistor, please

Pack control
Enable/Disable
Select to enable pack control.
Two packing algorithms define how and when packets are sent to
the network. The standard algorithm is optimized for applications in
which the unit is used in a local environment, allowing for very
small delays for single characters, while keeping the packet count
low. The alternate packing algorithm minimizes the packet count on
the network and is especially useful in applications in a routed Wide
Area Network (WAN). Adjusting parameters in this mode can
economize the network data stream.
The default setting is disable.
Idle gap time
Select idle gap time from 12, 52, 250 or 5000 msec.
After this idle gap time with no response from a serial device, data
is packetized and transmitted to the target. The default setting is
12.
Trigger character
Select packet size and set trigger character (hexadecimal digits).
Check sum
Select check sum size.

16
LNX-205 (Ver.1.0)
TCP keepalive
TCP keepalive time defines how many seconds LNX-205 waits
during an inactive connection before checking its status. If the unit
does not receive a response 7 consecutive times, it drops that
connection. Enter a value between 0 and 65 seconds. 0 disables
keepalive.
The default setting is 5.
Telnet Com port
control (RFC2217)
Set to enable when control COM port using Telnet.
The product enables a RFC2217 function to use a control signal used
in a serial port on a network. When it is not used this function, set
to disable.
I/O buffer clear
setting
Set it whether input/output buffer clear at the time of network
connection or disconnection.
Password setting
If you set a password for TCP connection, you must enter the
password before connecting. If you set a configuration password, you
can restrict access to the setting screen that is displayed by entering
the IP address from the browser.
TCP connection: half-width characters (up to 15 characters)
Configuration: half-width characters (up to 16 characters)
*Password is not read even if [Reading Data] or [Read from
Network] is performed with this tool.
* Password setting supported in product version 1.2 or later.
