Set up a Rexroth Controller

Ensure you have the correct Rexroth telematics cable.

The Rexroth GPS cable plugs into the AUX port on the bottom left of the display unit. If there isn’t a cable there, you will need to contact your Rexroth dealer to purchase either:

Connect the Samsara spreader cable to the Rexroth GPS cable.

Each cable model requires a specific male-to-male serial adapter. You can identify the correct adapter by the cable's serial number, which is printed on a white tape label near the point where the Rexroth cable connects to the spreader controller’s ACC port.

• Cable serial number R987400008: Use a null adapter (orange male-to-male serial adapter) and connect it to the female side of the Rexroth telematics cable. The other side of the Samsara cable plugs into the Samsara Vehicle Gateway.

• Cable serial number R987376776: Use a straight-through adapter (yellow male-to-male serial adapter) and connect it to the female side of the Rexroth telematics cable. The adapter is not included with the Samsara RS232 cable and must be purchased separately. The other side of the Samsara cable plugs into the Samsara Vehicle Gateway.

Configure the controller.

1. Use the USB configuration key to open the Rexroth configuration menu.

2. Press the padlock symbol to enter programming mode.

3. Access the menu via the gear icon on the upper right-hand corner of the display.

4. Verify the configuration settings.

   • Select avl to enable the Active Vehicle Locating Interface.

   • Clear GPS, if enabled.

5. Exit program mode to save changes.

6. Restart the Rexroth CS controller.

   The AVL symbol should appear over the gear on the home screen.

   If the AVL symbol is not active on the home screen, ensure that the Samsara RS-232 cable is securely connected to the Rexroth GPS cable with the correct adapter.

Verify that Samsara is receiving the spreader data.

1. Turn on the vehicle and turn the spreader controller dial to any amount.

2. From the Overview page on your Samsara dashboard, search for and then select the vehicle in the list that you want to test.

3. From the Graph Data drop down, select Spreader and ensure the date selector is set to display data for Today.

4. Verify that the graph displays material data reported by your spreader controller.
