2. Product Summary
LNX-002 is a LAN converter which makes it possible to use a RS-232C device via Ethernet
local area network.
Tunneling mode is available with a LNX-001 (USB to LAN converter) or one more LNX-002.
By using TCP/UDP or Telnet, direct control from PC is also available.
LNX-002 supports PoE function as a standard model, making 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-002.

Contents
IP address
If DHCP is not used to assign an IP address, enter it manually.
Unique IP address must be used in the network. The default
setting is 0.0.0.0 (DHCP is enabled)
Subnet mask
A subnet mask defines the number of bits taken from the IP
address that are assigned for the host part.
Default gateway
A gateway address of a router which is allowed to communicate to
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.
If you change the value, please avoid the following numbers. They
are allocated to other function.
1-1024
Reserved for well-known ports
9999 Reserved for telnet setup
14000-14009 Reserved for old redirector

Protocol
From the drop-down menu, select TCP or UDP.
Normally TCP is used, but when one-to-multiple communication
like broadcast or sensitive-responsiveness is needed, please select
UDP. The default setting is TCP.
Remote Setting
(Tunneling mode)
Enable/Disable
Select to enable remote connection (tunneling).
The default setting is disable.
Remote IP address
Enter the remote IP address of tunneling target.
Remote Port number
Enter the remote port number of tunneling target.
Connection method
Select connection method to the target.
Baudrate
LNX-002 and an attached serial device must agree on the baud
rate to use for the serial connection. Valid baud rates are 300, 600,
1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200, 230400,
460800 or 921600. The default setting is 9600.
Flow control
Flow control manages data flow between devices in a network to
ensure it is processed efficiently. Too much data arriving before a
device is prepared to receive it causes lost or retransmitted data.
Select from None, Xon/Xoff, Xon/Xoff Pass Chars to Host or
RTS/CTS (hardware). The default setting is none.
Stop bits
Select from 1 or 2 bit. The default setting is 1.
Parity
Select from Even, Odd or None. The default setting is none.
Data bits
Select from 7 or 8 bit. The default setting is 8.

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.

Contents
TCP keepalive
TCP keepalive time defines how many seconds LNX-002 waits
during an inactive connection before checking its status. If the unit
does not receive a response, it drops that connection. Enter a value
between 0
and 60 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 enable 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.
