# Setup

This chapter describes the setup procedure for the UX401 contactless reader.

## Selecting Reader Location

Use the following guidelines when selecting a location for your reader:

* Select a location convenient for the customer.
* Select a location near the controlling device for the contactless unit.

{% hint style="danger" %}
For safety, do not string cables or cords across a walkway.
{% endhint %}

{% hint style="warning" %}
Avoid placing metallic objects at the front of the card reader.
{% endhint %}

### Environmental Factors

The front panel of the device is dustproof and fade-proof. The UX401 is also water-resistant, in accordance with its IP65 ratings.

## Unpacking the Shipping Carton

Open the shipping carton and carefully inspect its contents for possible tampering or shipping damage.

1. Remove the items from the shipping carton. The standard package contains:

   * The UX401 contactless reader
   * One SMA (RF) coaxial cable
   * One RJ45 communication cable for connecting with the UX301 card reader.

   Refer to [Accessories and Documentation](/hardware-products/hardware/engage-devices/ux1-3-4xx-series/ux4xx/ux401-installation-guide/service-and-support.md#accessories-and-documentation) for more information about related accessories.
2. Remove any protective wrap before mounting the unit.

3. Save the shipping carton and packing material for future repacking or moving of the device.

   <div data-gb-custom-block data-tag="hint" data-style="danger" class="hint hint-danger"><p>Do not use a unit that has been damaged.</p><p>If a label or component appears damaged, please notify the shipping company and your Verifone service provider immediately.</p></div>

### Back Functions

The rear of the contactless device shows the following connectors:

* **RJ-45** host communication connector
* **SMA** (RF) antenna connector

## Connecting Unit to a Controlling Device

Use the following cables to connect the UX401 to the UX301 controlling device:

* 8-pin RJ45 to RJ45 (VPN CBL159-313-02-A)
* SMA cable, 0.8 m (VPN CBL159-302-03-A).

{% hint style="info" %}
For EMVCo L1 compliance, please use the provided cables.
{% endhint %}

**To connect to the
&#x20;UX301:**

Both connections are necessary for using the UX401 contactless unit.

1. Connect the RJ-45 plug to the rear of the UX401.

<figure><img src="/files/2Vc6M13ox7nhEBvOAecy" alt="" width="563"><figcaption><p>Figure 3: Connecting the UX401 to a Controlling Device</p></figcaption></figure>

2. Connect the 8-pin connector to the UX401 and the other to the UX301 port labeled "Ux401".
3. Screw in the SMA connector to the ports of the UX401 and UX301.

{% hint style="info" %}
To disconnect cables, use the same steps described above in reverse. If exchanging cables, use a Verifone-approved cable. See [Accessories and Documentation](/hardware-products/hardware/engage-devices/ux1-3-4xx-series/ux4xx/ux401-installation-guide/service-and-support.md#accessories-and-documentation) for cable ordering information.
{% endhint %}

## Contactless Support

This device supports the global contactless program specifications from American Express, MasterCard, Visa, Discover, ISIS SmartTap, and Google Wallet with virtually no changes to existing payment hardware or software.

## Mounting the Reader

The UX401 is designed to be flush-mounted to the mounting surface, without further need for any external mounting devices.

{% hint style="warning" %}
Ensure that your mounting frame has a thickness of 2 mm.
{% endhint %}

{% hint style="info" %}
Your mounting surface may have different installation instructions. Refer to your mounting device's user guide for further instructions.
{% endhint %}

**To mount the UX401:**

1. Peel off the plastic liner from the front of the unit.

<figure><img src="/files/thGOO6DsAbTdvctBBAeG" alt=""><figcaption><p>Figure 4: Mounting the UX401</p></figcaption></figure>

2. Align the unit's stud holes with the stud holes of your mounting surface.
3. Flush-mount the reader and secure the unit with M5 nuts.

{% hint style="warning" %}
Avoid placing metallic objects at the front of the card reader.
{% endhint %}

{% hint style="info" %}
Use M5 mounting studs with a minimum length of 12 mm.

Tighten the nuts using a recommended tightening torque of 7.0 kgfcm.
{% endhint %}

## Using the Reader

The contactless reader is only active when signaled by an application for the start of a contactless card transaction.

When active, the UX401's contactless logo lights up.

### Conducting a Contactless Transaction

To conduct a contactless transaction, hold the card (within 4 cm) or gently tap against the surface of the contactless antenna, marked by the logo.

<figure><img src="/files/AfUaKtb52O3DgJEkw2Ka" alt="" width="375"><figcaption><p>Figure 5: Conducting a Contactless Transaction</p></figcaption></figure>

The contactless unit uses various audible and visual confirmations to confirm transactions.

{% hint style="info" %}
The actual audible and visual confirmations may vary depending on regional and customer requirements.
{% endhint %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.verifone.com/hardware-products/hardware/engage-devices/ux1-3-4xx-series/ux4xx/ux401-installation-guide/setup.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
