E-Max (Air-Weigh) Smart OBM Setup Guide

Your Guide to Getting Started with Smart OBM and E-Max.

Welcome to Smart OBM with E-Max. This guide takes you through each step, from getting your E-Max on-board mass (OBM) system installed to receiving your Certificate of Enrolment. Work through the steps in order, and we'll keep you updated along the way.

Here's what's involved:



Step 1 — Set up your Smart OBM service

When you sign up for Smart OBM, your V-DAQ Account Manager or a member of our Sales team will set up your service and record E-Max (Air-Weigh) as your OBM supplier.

We'll then let E-Max (Air-Weigh) know you've chosen V-DAQ as your Smart OBM provider. You don't need to do anything else for this step.



Step 2 — Install and calibrate your E-Max system

Your E-Max system needs to be installed and calibrated by E-Max or one of their authorised installers. Contact E-Max to book a time.

When you book, ask E-Max to complete the following:

  1. Supply the gauges for each vehicle and asset (trailer or dolly) in the combination, plus the E-Max data cable, if they're not already fitted.
  2. Install and calibrate every part of the OBM system.
  3. Set up the system so each axle group reports its own weight.
  4. Turn on OBM streaming in the in-cab reader. The bottom row of the reader shows (OBM) when it's on.
  5. Complete the installation and calibration records and send them to E-Max at [E-MAX EMAIL ADDRESS].
  6. Check that a weight shows for every axle group on the in-cab reader.
  7. Let V-DAQ know once installation, calibration and setup are complete, so we can connect the system to your V-DAQ TAG.

Contact E-Max

E-Max provides installation and calibration guides with your system. Contact E-Max to request them.



Step 3 — Install the V-DAQ TAG

The V-DAQ TAG is the device that sends your weight data to the V-DAQ Platform. Install the TAG and power adaptor using the guides below. If a TAG is already installed in your prime mover, go straight to the next part of this step.

Connect the Bluetooth adaptor

We'll send you a Bluetooth adaptor that's already set up for your E-Max system, along with a security seal. The adaptor lets your E-Max system talk to the V-DAQ TAG. The E-Max data cable is purchased from E-Max.

  1. Connect the E-Max data cable to both ECU ports: the Printer / RS-232 port (data) and the Inclin port (power).
  2. Attach the Bluetooth adaptor to the 9-pin (DB9) plug on the data cable.
  3. Tighten the thumb screws.
  4. Place the V-DAQ security seal over the connection.
  5. Turn on the ECU, then check the blue Link light is on and the red Data light is flashing.

Note: The security seal shows us if the adaptor has been unplugged. It doesn't hold the adaptor in place. If no lights come on, the adaptor isn't getting power, so check the cable is connected to both ECU ports. If the red Data light doesn't flash, check OBM streaming is on: the bottom row of the in-cab reader shows (OBM) when it is.



Step 4 — Send your prime mover details to V-DAQ

To connect the TAG to your E-Max system and prepare your Installation Declaration, we need a few details about your prime mover:

  1. Prime mover Comlink ID. It's on the sticker on the back of the Comlink. If you can't read the sticker, go to ESC > SETUP > DIAGNOSTICS > COMLINKS > COMLINK ID on the in-cab reader.
  2. Prime mover registration and VIN. If it's easier, E-Max can send these to us for you.

Email these details to support@v-daq.com.au.

You don't need to send us your installation and calibration records. E-Max keeps these and reports them as part of your installation.

Important: Please send the Comlink ID exactly as it appears on the unit. We use it to pair your TAG, and it appears on your Installation Declaration.



Step 5 — Review and sign your Installation Declaration

We'll send you an Installation Declaration through the V-DAQ Platform. It confirms which TAG and OBM system are fitted to each vehicle.

  1. Check the details are correct: registration number, registered state, VIN (or non-VIN identifier), TAG serial number and OBM system serial number (the prime mover serial number).
  2. Sign the declaration in the V-DAQ Platform or the V-DAQ mobile app.

If anything is wrong, reply to the email with the correct details before you sign, and we'll update it for you.



Step 6 — Data verification

Next, we check the data coming from your vehicle to make sure everything is working correctly. Before we start, please make sure:

  • The in-cab reader shows a weight for every axle group.
  • The V-DAQ TAG and OBM system are powered on.
  • The vehicle has been driven for at least 30 minutes.

Once that's done, email support@v-daq.com.au with your vehicle registration to let us know you're ready.

Important: We need to verify your data before we can enrol your vehicle. We check that weight records arrive every 5 minutes, that every axle group reports a weight, and that the combination matches your installation records.



Step 7 — Enrolment

Once your data is verified, we'll enrol your vehicle in all applicable schemes. You'll then receive a notification from the V-DAQ Platform with your Certificate of Enrolment.

Each prime mover gets its own certificate, named with its registration. We recommend you:

  1. View and save each certificate.
  2. Check the vehicle and company details are correct.
  3. Print a copy and keep it in the vehicle.
