FlexWash sends wash codes to a Laguna Remote Tunnel Controller (r-TC) over Ethernet. The controller keeps running the tunnel. Complete the steps below. FlexWash handles the rest.
These settings apply to the Laguna r-TC only. Other r-TC variants use different network parameters.

​
Before you start

  • The FlexWash switch and coordinator are installed and online. See On-Prem Installation.
  • A contact at Laguna, they normally set the WAN parameters and enables Ethernet on your packages. An experienced technician can do both instead, with the router and r-TC web interface passwords from Laguna.
  • Access to the r-TC network if you are performing these steps yourself, either a laptop connected to it or the HMI.

​
Step 1. Connect the r-TC router to the FlexWash switch

Run an Ethernet cable from port 23 on the FlexWash switch to Laguna’s router, which sits inside the controller enclosure.
The cable must go into the router’s WAN port. A LAN port will not work for Laguna’s r-TC.

Step 2. Set the WAN parameters on the r-TC router

1

Open the router interface

Navigate to 192.168.1.91.

Log in

Credentials vary by site. Factory credentials sometimes work. If they do not, contact Laguna for the password.

Apply these settings

The router brand varies between sites. Asus, Cudy, Linksys, and others all appear, so your screens may not match the screenshots below, which come from a Cudy router. The settings and values are the same regardless of brand.

Step 3. Enable Ethernet in the r-TC web interface

Laguna normally performs this step. An experienced technician can do it instead. The r-TC web interface is at 192.168.1.80, the Ethernet option must be enabled on every one of your wash packages and retracts. FlexWash cannot trigger anything without it. Ethernet enabled on a wash package

Step 4. Provide your wash codes

Each wash package carries a numerical wash code. Send the codes to your onboarding specialist or to Customer Support. FlexWash maps them to your packages. Wash codes

What happens next

FlexWash completes the integration on our side, which includes registering the controller and mapping your wash codes. When that is done, we test a wash and a retract with you before the site goes live. Once the controller is live, see Retracts to configure which equipment can be pulled back per vehicle.
