  • I/O leads for 2 Digital inputs and one1 Digital output for sensors such as PTO
  • Long life, replaceable backup battery pack. How to replace EAT battery pack
  • Optimised internal antenna design for improved signal reception
  • Status button that wakes the device, initiates the status test and prompts the device to send a report.
  • LED status indicators for Battery, Network, and GPS
  • 2-wire or 3-wire installation options

 

Identifying the EAT device

EAT_product_shot.png

Before getting started, be aware that there are two Verizon Connect devices that look alike, EAT and EAT-B. This installation guide deals with the EAT device.

The EAT device is powered by the equipment, that is, the asset, and therefore has a power cable attached to it. If the device you are installing does not have the cable, then it is the EAT-B device, not the EAT device. If you are installing the EAT-B device, refer instead to the Verizon Connect Equipment Asset Tracker- Battery installation guide.

 

Status button

EAT_status_button.png

  • For a new device out of the box or a device that has had the battery replaced, the status button turns the device on.
  • For a device already in operation, the button wakes up the device.
  • Whenever the status button is pressed, the device:
    • Performs status checks for device battery level, network connection and GPS.
    • When connected to both the network and GPS, the device then sends a location update (check-in) to Reveal, in addition to its usual check-in schedule.

The status button does not turn the device off, which is why we don’t call it a power button. Should there be a reason to take the device out of operation, the device’s back cover can be removed, and the battery pack disconnected.

 

Device label

EAT_device_label.png

The label with S/N and IMEI barcodes is found on the side of the device, which allows it to be read even after mounting. You will scan the label when instructed in the Reveal Hardware Installer app, or if the scan should fail, enter the IMEI. The text on the device label is small, so if difficult to read, you can refer to the enlarged label found on the box that came with the device. The box label is also scannable.

Status LEDs
EAT_status_LEDs.png

The device runs a status test for Battery, Network, and GPS whenever the status button is pressed. Status test results are displayed on the status LEDs as described below. The LEDs stay lit only for a brief duration. However, the test can be repeated by pressing the status button again, which is useful for determining the best place on the asset to mount the device.

Icon Name Status Notes
Battery_LED.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.

During the first phase of beta testing, battery status will not function as described.

Network_LED.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__LED.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__LED.png Bluetooth At this time, the device does not support any Bluetooth features. 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.

  • The 1-Wire I/O wire will not be used at launch but is planned for a later phase.
  • The three black ground wires are commoned together at the exposed end, giving the appearance of being one wire.
  • The colours shown are for Phase 1 Beta. For Phase 2 Beta, the colours for Digital Input 1 and Digital Input 2 Low wires will be changed. (This information will be updated once confirmed for Phase 2 Beta).

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

To prevent chafing, run the harness cable through a pass-through hole, using existing holes to pass the cable through rather than drilling a new one. If drilling is necessary, always check before you drill to verify 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.

EAT_grommet.png

Because the device and its wires will usually be exposed to the elements, heat-shrink butt connectors and ring terminals should be used instead of splicing wires. These connectors are preferred instead of splicing, even when wires will not be exposed to the elements, as being much better at preventing air and moisture from reaching wires and causing corrosion.

Heat-shrink butt connector:

Heat_shrink_butt_connector.png

Heat-shrink ring terminal:

Heat-shrink_ring_terminal.png

In addition, create a drip loop to prevent moisture from running down the length of the wire toward devices and connections.

 

Wire splicing

If for some reason using butt connectors and ring connectors is not practical, and if wires will not be exposed to the elements (for example, wires lying internally 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.
    Split_the_wire.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.

2-wire versus 3-wire installation

Determine whether you are doing a 2-wire or 3-wire installation. The Reveal Hardware Installer app will ask you to select one or the other. The 2-wire method is typically used on trailers while the 3-wire method is typically used on heavy equipment “yellow iron” assets such as backhoes and bulldozers.

2-Wire installation steps

  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/centre 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 colours and pin layout for a tractor-trailer 7-way connector.)
    Wire_colours.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.

3-Wire Installation Steps

  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.

 

3-Wire Installation 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 completing the installation as instructed in the Reveal Hardware Installer app.

Sensor inputs, for functions such as PTO, boom, rear door, or lights are an optional part of the installation. If the installation does not call for inputs, proceed to complete the installation as instructed in the Reveal Hardware Installer app.

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 energise a relay coil, or functions such as buzzer or 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.

Mounting the device

Mounting_the_device.png

This section provides information about where to mount the device and how to mount it.

 

Where to mount the device

Where the device is mounted depends partly on the type of asset, but the device’s long harness enables a variety of options.

The most important thing to remember is to first hold the device where you intend to mount it and test for Network and GPS before you start drilling holes. You perform the test by pressing the device’s status button and reading the LED status lights. If the LEDs do not indicate successful connection to Network and a GPS location fix, repeat the test elsewhere on the asset until network connection and GPS fix are successful.

  • Make sure the asset itself is not located where the network or GPS signals may be diminished during installation, for example, under a metal shed.
  • Even though the device is IP67 rated, 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.
  • Good spots for mounting on trailers include on top of the trailer’s tongue or the hitch rail, side rails or front bulkhead.
    • Use the included mounting hardware. Do not use rivets or countersink screws. Do not over torque. Over torqueing or using the wrong mounting hardware can cause the plastic surrounding the mounting hole to crack.
  • Installation requiring the use of a ladder is not advised. However, if working at height, it is your responsibility to ensure use of safety equipment and proper safety procedures are followed.
  • The device’s omnidirectional antennas allow the device to be mounted facing up or sideways, facing out.
  • Do not mount the device facing down, underneath the asset because ground reflections will impair signal reception and reporting accuracy.
  • Be aware that mounting the device under the floor, especially if it is an enclosed metal trailer or container, as opposed to an open flatbed, can limit connectivity and data. transmission. As already mentioned, always confirm the status of network signal and GPS by using the device’s status button and status LEDs at the precise mounting location before mounting the device.

 

How to mount the device

After a successful Network and GPS test, and after completing the device setup and activation in the Reveal Hardware Installer app.

  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 over torque. Do not use rivets or countersink screws. Over torqueing or using the wrong mounting hardware can cause the plastic surrounding the mounting hole to crack.
