Note
The device's serial number (SN) and IMEI number are also on the box label.
Note
Pressing the status button does not power off the device.
Record the device's serial number (SN). You will need it later when confirming the device has connected to Reveal.
Note
The device's serial number is on the device label (see Step 3 above).
Note
If using the Reveal Hardware Installer app, the app will instruct you to scan the label. Both the device label and the box label are scannable.
In the Reveal Hardware Installer app, as you go through the installation steps, you will be instructed to press the device's status button before mounting the device. This will activate and test the device.
-
Hold the device in the mounting location.
-
Press the status button firmly for 1-3 seconds to wake the device.*
-
Avoid pressing the status button for too long because this can put the device in Bluetooth pairing mode. Bluetooth features are not currently supported in the device. If you put the device in Bluetooth pairing mode, wait about 30 seconds until the Bluetooth LED stops flashing and then press the status button for 1-3 seconds to restart the network check.
-
-
Press the status button again to start the status check.
-
Check the status LEDs. (See table in the Status LEDs section below.)
If your tracker's HW Rev is "A.1.1" or lower on the device label, you need to apply additional force to press the status button.
Instead of using only your finger, use a capped pen at an angle to press the bottom edge of the button for 1-3 seconds to wake the device.
If powering up the device for the first time, two presses may be needed. The first press to wake the device, and the second press to start the network status check.
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.

Warning
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.
Where the device is mounted depends partly on the type of asset.
Caution
Network and GPS connections are required at the mounting location.
-
Hold the device where you intend to mount it.
-
Test for Network and GPS by pressing the device's status button and reading the LED status lights.
-
If the LEDs do not indicate successful connection to the network, and a GPS location fix; choose another location and test again 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.
-
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.
-
We do not recommend mounting the device facing down, underneath the asset, because ground reflections can impair reporting accuracy.
Possible locations include:
-
Top of the trailer’s tongue
-
Hitch rail
-
Side rails
-
Front bulkhead
Note
The device is mounted in a later step.
If the EAT device is installed using a 2-wire connection, set it to a 2-wire configuration as follows:
-
Get the device Serial Number (see Step 4: Record the device serial number).
-
Contact the Technician Support Line and supply the device Serial Number.
-
Request that the device be set to a 2-wire configuration.
At this time, an EAT device 2-wire or 3-wire configuration setting can only be set through Technician Support.
Using the Reveal Hardware Installer App, prior to mounting the device on the asset, you will:
-
Select the work order and then scan the device barcode or enter the device ESN.
-
Select Multi PWRD Asset Devices from the list. (Note that the selection applies to all asset trackers, for powered or non-powered assets.)
-
Test the device for network connectivity and GPS location fix. (See Step 5: Activate and test the device and section Status LEDs).
-
Select the wiring method (2-wire or 3-wire). (See Wiring the device.)
-
Enter the asset information.
-
Wire and mount the device to the asset (see Step 9: Mount the device). After wiring and before mounting, press the status button again to confirm the Network and GPS LEDs light up when the device is wired.
-
Complete device setup and activation.
Note
At this time, the EAT device's configuration (2-wire or 3-wire) can only be set through Technician Support.
In this step:
-
Connecting to digital input/output sensors
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 Reveal Hardware Installer app will ask you to select one or the other.
-
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.
The EAT device is capable of sensing voltage transitions of at least 6 volts on 12/24-volt systems and requires 3 mA current when voltage is present in the on phase. 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.
Note
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.
The device uses a trigger wire/reference wire setup method for each sensor input. Therefore, each sensor input requires both wires be connected to complete each input.
How to wire sensor inputs
Use the methods below to make trigger wire and reference wire colour connections. If you require monitoring 2 sensors and both have the same polarity simply wire both inputs identically.
For positive sensor triggers, Use the solid colour input wire for the positive trigger. Use the striped colour input wire for the reference wire/input ground.
For negative sensor triggers, use the striped colour input wire for the negative trigger. Use the solid colour input wire for the reference wire/+VDC reference voltage.
The EAT device has a molded 15.4 ft (4.7 m) long power and I/O harness terminating with these colour-coded wires with bare leads:

One-Wire I/O is not available at this time 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.
Do not separate the ground wires and attempt to use them as individual ground wires.
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.
-
Connect the device’s red wire to the asset’s +12/24V constant power source.
-
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.
-
Coil up and zip tie any extra length of the device harness.
Caution
Don't cut the harness to shorten it unless the customer requests this. Shortening the harness limits the device’s usability if transferred to another asset in future, and it makes wiring errors more likely.
2-Wire installation for nose-mounted semi-trailers using a 7-way connector
-
Remove the 7-pin connector’s mounting plate.
-
Mount the unit to the trailer using the provided mounting hardware.
-
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.
-
Push the harness end down the interior side of the 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.
-
-
Pull the wiring harness through at the 7-pin connector.
-
Reattach the fused links using heat shrink butt connectors, and verify a 3-5-amp fuse is present.
-
Separate the black and red wires from the harness.
-
Tape any unused harness wires to the harness sheath (do not cut to custom length).
-
-
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.
-
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 or the poke-and-wrap method.
Caution
Do not connect the red power wire to the marker or running lights unless it is specifically requested by Verizon Connect.
7-pin connector diagram for semi-trailers
This semi-trailer 7-pin connector diagram is SAE J560 compliant and shows typical wiring colours and pin layout.
Warning
The EAT's red wire must be connected to battery positive power via the semi trailer's AUX/ABS circuit which is colour coded blue by the J560 spec and corresponds to pin #7 in the centre when facing the 7-pin connector.
-
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.
-
Remount the 7-pin cover plate.
Refer to the typical wiring colours and pin layout above.
Connect the device’s red power wire to the trailer’s blue auxiliary wire.
Connect the device’s black ground wire to the trailer’s white ground wire.
Caution
Do not connect the red power wire to the marker or running lights unless it is specifically requested by Verizon Connect.
-
Connect the device’s Red VDC power wire to the asset’s +12/24 VDC constant battery power source. If installing on a semi-trailer, use the AUX/ABS wire (located on the 7-pin) for power.
-
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.
-
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.
-
Coil up and zip tie any extra length of the device harness.
Caution
Don't cut the harness to shorten it unless the customer requests this. Shortening the harness limits the device’s usability if transferred to another asset in future, and it makes wiring errors more likely.
3-Wire Installation for refrigeration (reefer) trailers
Most trailers require 2-wire installation but refrigeration (reefer) trailers usually require 3-wire installation. In addition to the primary three wires, a digital input wire should be used to enable monitoring of the reefer’s engine hours via the reefer’s ignition circuit.
Warning
Installations that require the use of a ladder are not advised. However, if working at height, it is your responsibility to ensure proper safety procedures are followed.
Note
Before drilling, always check to ensure you will not damage any adjacent equipment or ROPS structures.
-
Ensure the asset is in a location that has a good GPS and network signal. Avoid locations that are likely to have poor signals (for example, inside buildings or beneath metal sheds).
-
Move the device to where you plan to mount it, and activate and test it as follows.
-
Press the status button once to wake the device.
-
Press the status button a second time to initiate the device status checks.
A solid cell network LED light indicates a successful network connection.
A slow blinking GPS LED indicates the device is searching for a GPS signal (it does not indicate successful GPS signal lock).
-
-
Holding the device firmly in the location where it will be mounted, carefully mark the positions of the four mounting holes.
-
When satisfied with the mounting location, drill the mounting holes.
Note
Pre-drilling mounting holes makes it easier to insert mounting screws.
-
Secure the device to the asset using the included screws or bolts.
Caution
Don't use rivets or countersunk screws to secure the device. Don't over-torque the screws or bolts. (This could crack or break the plastic around the mounting holes.)
Refer to EAT mounting and orientation tips for examples of install locations on semi-trailers, flatbeds and lowboy trailers; and details of Verizon Connect's preferred mounting orientation guidance.
Caution
How you mount or orient the device can affect how well it performs.
Mounting the device beneath floorboards, inside enclosed metal trailers or inside containers can limit signal acquisition and data transmission. We do not recommend mounting the device facing down beneath an asset, because doing so can impair reporting accuracy.
Even though the EAT is IP67 rated, it is still recommended to keep it clear of high-pressure water spray. You should also avoid sources of high heat (+180°F / 82°C), moving parts and areas that will expose it to damage by debris.
When mounting the device vertically on a vertical surface, the preferred orientation is with the Verizon check mark right side up. This puts the status button at the bottom where it is less exposed to the elements.
When mounting the device horizontally on a vertical surface, the preferred orientation is with the device label (label not shown in the picture) facing down. This will help keep the label from getting worn by the elements.
