2. Product Summary
LNX-203 is a 2 channel RS-232C LAN converter which makes it possible to use 2
channels of RS-232C port from single LAN port via Ethernet local area network.
Tunneling mode (transparent mode: connected on one-to-one connection without
PC) is available with LNX-203 using LAN. By using TCP/UDP or Telnet, direct
control from PC is also available.
LNX-203 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-203.

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
30704 Reserved for remote control of user I/Os
30718

LNX-203 (Ver.1.0)
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.
Baudrate
LNX-203 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.

Contents
TCP keepalive
TCP keepalive time defines how many seconds LNX-203 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 65 seconds. 0 disables keepalive.
The default setting is 5.
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.
