overview

　The LNX-203 is a LAN converter that can use two RS-232C ports via Ethernet. It can be used in tunneling mode (transparent mode/1:1 communication without going through a PC) when connected to
the LNX-002
. It can also be connected between LNX-203s. It is also possible to connect directly to the LNX-203 from a PC using TCP/UDP or Telnet.
　It comes standard with a PoE function, so it can be powered from a LAN cable. (A PoE-compatible HUB or similar is required.) It can also be operated using the included AC adapter.

• August 5,  2021LNX-203 will be discontinued after it is sold out.

Features

• Media converter function that converts 2-port RS-232C to LAN
• Two LNX-203 units can be used for 1:1 connection in tunneling mode (transparent mode).
• Automatically detects 10Base-T/100Base-TX
• Easy device setup with setting memory card (microSD)
  • When replacing equipment, you can easily migrate by replacing the setting memory card.
  • Setting data can be sent to remote locations via email attachments, etc.
  • There are no restrictions on the IP address that can be set (can be set outside the segment)
  • Easily back up and record settings by saving the settings file
• Device settings can also be configured via network (LAN) using the original setting tool.
• PoE compatible, so power can be supplied via LAN cable
• Virtual COM port support
• Industrial Design
• Free of 10 substances restricted by the RoHS Directive

Connection Topology

[Tunneling connection between LNX-203]

　LNX-203 can communicate directly with each other and connect RS-232 to each other without the need for a PC.

[Tunneling connection between LNX-203 and LNX-002 (2 units)]

　The LNX-203 and LNX-002 can communicate directly without the need for a PC, and can connect RS-232 devices together. This
is useful when the RS232C device on the LNX-002 side is far away.

[LNX-203 only]

 
 You can communicate with RS-232C devices in remote locations using Ethernet.

[Directly connect the LNX-203 to a LAN-compatible printer and output directly from a microcomputer or PLC]

　By connecting to the LNX-203 via an RS-232C interface such as a microcontroller or PLC, you can print to various remote network-compatible printers
. *Please check with the demo unit to see if you can actually achieve the desired results.

LNX series setting tool

　This is an application for creating setting data for the LNX series.

　The created setting data is automatically configured by inserting it into the setting memory card (microSD) and turning on the power.
At this time, a backup file of the setting data is created on the setting memory card (microSD).
The setting data is saved even when the power is turned off, so there is no need to insert the microSD card next time.
When replacing the main unit of the LNX series, you can easily set it to the same settings by using the setting memory card (microSD).
If the PC and product are connected in the same segment, you can also configure it via the network (LAN).
