Introduction
Thank you very much for purchasing our product LNX-204.
LNX-204 is a LAN multiplexer to switch 4 channel LAN port. LNX-204 can change
the port physically by three ways: send simple command from PC via LAN, input
control signal from an external contact point or change switches of the product
body.

2. Product Summary
LNX-204 is a LAN multiplexer to switch 4 channel LAN port. LNX-204 can change
the port physically by three ways: send simple command from PC via LAN, input
control signal from an external contact point 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-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.

GND, the LAN port is switched.
e.g. Short SEL3 (pin no. 3) with GND (pin no.5): Common LAN port and LAN3 port
is connected.
* #4-40 UNC screws are mounted by factory setting. You can change them to attached
M2.6 screws.
* COM (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
contact us.

Subnet mask
A subnet mask defines the number of bits taken from the IP
address that are assigned for the host part.
Default gateway

other LAN segments. This address should be an IP address of the
router which is in the same LAN segment.
Port number
Enter the local port number. The default setting is 10001.

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-204 (Ver.1.1)
TCP keepalive
TCP keepalive time defines how many seconds LNX-204 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.
