LocoNet WiFi Interface

LNWI or LocoNet Wifi Interface is a device that allows you to connect WiFi devices to LocoNet.

  • Wi-Fi interface to a Digitrax LocoNet
  • Connect four compatible mobile Wi-Fi devices and Apps.
    • Compatible with most Android and Apple devices running supported throttle apps
  • Works ‘out of the box’, with no additional configuration required.
  • Provides up to 32 LocoNet Throttle functionality per LNWI, with compatible apps and Command Station.
  • Up to a maximum of 8 LNWI can be supported per LocoNet, allowing up to 32 wireless devices
  • Multiple LNWI units automatically resolve SSID with no additional configuration when track power is turned on.
  • Optional Wi-Fi WPA security. This prevents unauthorized throttles from connecting (such as at a show).
  • Customize all device settings
  • LocoNet Compatible

When using the LNWI your devices will not be connected to the internet. Maximum of 4 connections, additional attempts will fail.

Connection Issues

The channel used by the LNWI must match that of the UR92.

  • The UR92 only supports channels 11 – 26 for duplex throttle operation.
  • The LNWI can only connect to channels 11 – 21.
  • The LocoNet Group Name must match between the UR92 and LNWI
  • It is possible to alter the IP address if necessary
  • Port number is 12090
  • When a device connects to the LNWI, all internet-based features will be lost.


The LNWI supports WPA2 to prevent unauthorized access to the network. A password is required to access the network from a wireless device. See Option Switches below.
