overview

　The LNX-503W is a converter that can communicate with 2-wire (half-duplex) RS-485 devices located at a distance via Wi-Fi.
For communication with 4-wire (full-duplex) RS-485/422 devices, the LNX-504W is available.
It supports dual-band (2.4GHz/5GHz) IEEE 802.11a/b/g/n wireless standards and can be used in various Wi-Fi environments.
　It supports multiple connections for up to four devices at the same time, allowing communication with RS-485 devices from multiple PCs or tablets. The baud rate on the RS-485 side can be set to a custom (arbitrary) baud rate within the range of 9,600 to 4M bps. It is possible to
　install multiple LNX-503Ws and connect them in tunneling mode without going through a PC. It can also be used to wirelessly connect RS-485 devices to each other via Wi-Fi and extend the signal.
　Various settings such as Wi-Fi and serial communication can be easily written via USB using our original setting tool (LNX SETTING TOOL). Setting data can also be backed up and imported, allowing multiple devices to be set up quickly and sequentially.

*Cannot be used overseas as it requires certification according to the radio laws of each country.

Connection Topology

[LNX-503W only (terminal mode)]

    Wifi   

You can communicate with RS-485 devices located far away from your PC via an access point such as a Wi-Fi router.

[LNX-503W alone (Access Point Mode)]

  Wifi  

The built-in access point function of the product allows communication with RS-485 devices in remote locations.

[Tunneling connection between LNX-503W]

   Wifi  

LNX-503W can communicate directly with each other without the need for a PC, and RS-485 can be made wireless and extended.

[Connect LNX-011W and LNX-503W via tunneling and use RS-485]

   Wifi 

You can communicate with RS-485 devices in remote locations via Wi-Fi from the USB interface. For communication with
the LNX-011W,
you can use FTDI's virtual COM port or D2XX-API. No network knowledge is required for programming.
