Installing the device

Step 1: Make note of the SN (serial number) located on the device.

You need this number later when confirming that the device has connected to Reveal. You can find the serial number on the label on the side of the device.

Step 2: Find a good location to mount the device.

Where the device is mounted depends partly on the type of powered asset.

When choosing a mounting location, consider the following:

  • Keep the device clear of moving parts or areas that will expose the device to road debris or high-pressure water spray. Also, 
  • Do not mount the device next to any heat-generating machinery.
  • The device’s omnidirectional antennas allow the device to be mounted facing up or sideways, facing out.
  • Mounting the device under the floor, especially if it is an enclosed metal trailer or container and especially if the device is facing down, can limit connection to the network. 

Possible locations include:

  • Top of the trailer’s tongue
  • Hitch rail
  • Side rails
  • Front bulkhead

Do not mount the device until you have activated and tested the device.

Step 3: Activate and test the device.

  1. Hold the device in the mounting location.
  2. Press the status button for 1-3 seconds to wake the device.*
  3.  Press the status button again to start the status check.
  4. Check the status LEDs.

* Designed to prevent accidental activation when shipping, the status button requires a firm, short press ( and release. Rather than using your finger, it is easier to use a blunt tool to press the button.

Status LEDs

Icon Name Status Notes
Battery_EAT.png Battery
  • 1 flash = 10-25% full
  • 2 flashes = 25 - 50% full
  • 3 flashes  =  50 - 75% full
  • 4 flashes = 75 - 100% full
After pressing the power button, battery status is given almost immediately.
Network_EAT.png Network
  • Slow flash: device is seeking network.
  • Solid: network connection acquired
  • Fast flash: network connection failed.
After pressing the power button, network status (success or failure) is given within about 10 seconds and stays on for about 15 seconds.
GPS__EAT.png GPS
  • Slow flash: device is seeking GPS.
  • Solid: GPS location acquired.
  • Fast flash: GPS location failed.
After pressing the power button, GPS status (success or failure) is given within about 30 seconds and stays on for about 15 seconds.
BlueTooth__EAT.png Bluetooth The Bluetooth LED will flash when the device is powered on, but it has no use to the installer and does not have any test/status function. It can be disregarded. At this time, the device does not support any Bluetooth features.

The device runs a status test for battery, network, and GPS.

It can take up to 30 seconds for the LEDs to light up and they stay on for 5 seconds. To recheck the status, press the status button again. Pressing the Status button does not power off the device.

Step 4: Connect the device to a power source

The EAT device is powered by the asset you are installing the device into. You can connect to the asset’s power source using a 2-wire or 3-wire connection. 

The 2-wire method is typically used on trailers.

The 3-wire method, where the third wire is connected to ignition, is typically used on heavy equipment (yellow iron) assets such as backhoes and bulldozers.

Before you begin, familiarize yourself with the wiring harness.

Device harness wiring layout

The EAT device has a molded 15.4’ long power and I/O harness terminating with these color-coded wires with bare leads:

One-Wire I/O (not used)*

26 AWG

  • One-Wire I/O will not be used at launch but is planned for a later phase.  
  • The ground wire is actually three ground wires joined together at the exposed end, giving the appearance of being a single wire.

About the sensor wiring connections (digital inputs)

The EAT device is capable of sensing voltage transitions of at least 6 volts on 12/24 volt systems and requires 3mA current when voltage is present in the on phase. 

The device uses a trigger wire/reference wire setup method for each sensor input. Therefore, each input requires two connections to complete each input. 

The signal to be monitored should have two voltage states. One with no voltage (that is, zero volts when referenced to ground) and another that falls in the range from 6 to 24 volts. 

For sensor inputs, use one of the methods below for trigger wire and reference wire color connections.  

If you are wiring for a positive trigger:

  • Use the solid color input wire for the positive trigger.
  • Use the striped color input wire for the reference wire/input ground.

If you are wiring for a negative trigger:

  • Use the striped color input wire for the negative trigger.
  • Use the solid color input wire for the reference wire/+VDC reference voltage.

It is important that the voltage signal is tested to ensure it is continuously providing the necessary voltage and current when in the on or active position.

Fuses

EAT_Fuse_Holders.png

The device harness includes two weather-proof fuse holders, each holding a 3A mini-blade replaceable fuse. Therefore, there is no need to splice in any fuses during installation. Replacement fuses, if needed, can be purchased from any auto parts store. The fuses are located on the device’s red VDC power wire and white ignition wire.

Wiring Best Practices

  • Run the harness cable through a pass-through hole, using existing holes to pass the cable through rather than drilling new ones.  This prevents the wire chafing
  • If drilling is necessary, check that you are not drilling into anything unintended behind the drilling surface. Insert a grommet, that is the right size and type for the hole, into the newly drilled hole to protect the wire and seal with all-weather silicone as necessary.

  • Use heat-shrink butt connectors and ring terminals rather than splicing wires, as the device and its wires are usually exposed to the elements. These connectors are also better at preventing air and moisture from reaching the wires and causing corrosion.

Heat-shrink butt connector:

Heat-shrink ring terminal:

  • Create a drip loop to prevent moisture from running down the length of the wire toward devices and connections.

Wire splicing

If using butt connectors and ring connectors is not practical, and if wires will not be exposed to the elements (for example, the wires are  within the asset’s cab) any splicing should be done by using the standard poke and wrap technique.

  1. Remove approximately one inch of wire insulation.
  2. Split the wire in half making an oval and push the wire to be terminated through that hole.Splice_wire_poke_and_wrap.png
  3. Press the wire back together then wrap the excess newly inserted wire tightly around it.
  4. Wrap the new splice with Super 33 or better electrical tape.
  5. Apply two wire ties to the splice. The first goes over the splice and the other approximately one inch down the line of splice.

Connect to the power source using the two-wire method

  1. Connect the device’s red wire to the asset’s +12/24V constant power source. 
  2. Use a ring terminal to connect the device’s black ground wire to the asset’s negative battery terminal or use a self-tapping screw and a ring terminal to connect the device’s black ground wire to a chassis ground.
  3. Coil up and zip tie any extra length of the device harness. Do not cut the harness to shorten it, as doing so limits the device’s usability if transferred to another asset in the future and also increases the chance of making an error with wiring.

2-Wire installation for nose-mounted semi-trailers using a 7-way connector

  1. Remove the 7-pin connector’s mounting plate.

  2. Mount the unit to the trailer using provided mounting hardware.

  3. Use an existing pass-through hole or, if one is not available to use, drill a new pass-through hole into the trailer skin. If it’s a new hole, pull the harness through a grommet.

  4. Push harness end down interior side of trailer wall toward the 7 way connector.

    • If it will be necessary for the harness to pass through, clip off the preinstalled fused links from the device harness.

    • Make a drip loop in the harness to prevent condensation from running towards electrical connections.

    • If a grommet is used, insert it into the pass-through hole. Apply a bead of silicone around the grommet to seal the pass-through.

  5. Pull the wiring harness through at the 7 pin connector.

  6. Reattach the fused links using heat shrink butt connectors, and verify a 3-5 amp fuse is present.

  7. Separate the black and red wires from the harness.

    • Tape any unused harness wires to the harness sheath (do not cut to custom length).

  8. Connect the device’s black ground wire to the trailer’s white wire/top pin on the 7-way trailer stud using a heat shrink ring terminal or poke-and-wrap method.

  9. Connect the device’s red VDC power wire to the trailer’s blue “aux” wire/center pin on the 7-way trailer wire stud using a heat shrink ring terminal poke-and-wrap method. Alternatively, the marker or running lights wire can be used instead of the aux wire. Shown below are the typical wiring colors and pin layout for a tractor-trailer 7-way connector.
    7-Way_Connector.png

  10. Coat both newly installed ring terminal connections with dielectric grease or terminal protecting anti corrosion spray as necessary, and use a wire loom to protect any remaining exposed wiring portions not protected by the device’s wire harness jacket.

  11. Remount the 7-pin cover plate.

Connect to the power source using the 3-wire method

  1. Connect the device’s Red VDC power wire to the asset’s +12/24 VDC constant battery power source.
  2. Connect the device’s Black Ground wire to the asset's negative battery terminal. If that is not practical, connect instead to a chassis ground on the asset by using a ring terminal and self-tapping screw or factory bolt.
  3. Connect the device’s white Ignition wire to the asset’s +12/24 VDC ignition/switched power. The asset’s ignition source will vary depending on the type of asset; it could be located at the asset’s ignition switch or at the asset’s  fuse box.
  4. Coil up and zip tie any extra length of the device harness. Do not cut the harness to shorten it, as doing so limits the device’s usability if transferred to another asset in the future and also increases the chance of making an error with wiring.

Additional connections for reefer trailers

While most trailers require 2-wire installation, Reefer trailers are an exception, usually requiring 3-wire installation. In addition to the primary three wires, a digital input wire should be used to enable monitoring the reefer’s engine hours via the reefer’s ignition circuit.

Connecting to digital input/output sensors

After installing the primary device wiring, you can proceed to the I/O wiring for sensors, if called for in the work order. Sensor functions such as PTO, boom, rear door, or lights are an optional part of the installation. If installation does not include I/O wiring, disregard this section and proceed to the Mounting the Device section of this article

As shown in the device harness wiring layout, the EAT device has these I/O options: 

  • Two digital inputs. These inputs can switch between either positive or negative polarity, so no relays are required. As shown in the Device Harness Wiring Layout section, each of the two inputs has two wire leads, for high (positive) and low (negative). With each input used, both wires must be connected.
  • One digital output. Digital output provides a negative 200 mA output. Digital output is typically used to energize a relay coil, or functions such as a buzzer or an  LED.
  • One-Wire input and output (one wire for both). One-Wire I/O is not yet supported by this device; therefore, the device’s grey One-Wire lead is not used at this time, but is planned for a later phase of the product.

Step 5: Check that the device is reporting to Verizon Connect.

The asset should be listed in Reveal and Spotlight with the serial number as the asset name. You can search for the asset to confirm that it is successfully connected to Verizon Connect.

To check for the device in Spotlight:

  1. In Spotlight, go to the Map screen.
    Asset_in_Spotlight.png
  2. In the Search field, enter the device serial number and tap Search.

To check for the device in Reveal:

  1. In Reveal, go to Admin > Asset List.
    Asset_List.png
  2. In the Search field, type the device serial number and press Enter.
    If the asset is connected, it shows in the list.

Step 6: Mount the device

Once you have activated and tested the device, you can mount it to the asset.

To mount the device:

  1. Hold the device where it will be mounted mark the positions of the four mounting holes where you will drill.
  2.  If using the screws, pre-drilling the holes is recommended.
  3. Secure the device to the asset using the included screws or bolts.
    Do not use rivets or countersink screws. Do not over torque. Over torquing or using the wrong mounting hardware can cause the plastic surrounding the mounting hole to crack.

Step 7: Rename the asset in Reveal

The asset is listed in Reveal with the serial number as the asset name. We recommend that you rename the asset so that it’s easier to identify on Live Map and in your reports.

To rename the asset:

  1. In Reveal, go to Admin > Asset List.
    Edit_the_asset_name.png
  2. In the Search field, type the device serial number and press Enter.
  3. Choose the Edit icon next to the asset.
  4. Enter a unique asset name and asset number.
  5. Choose SAVE CHANGES.
