### Assemble Base Station

Setup the tripod. 

Then insert the power bank in the base station, then mount the base station to the tripod.

{% endstep %}

{% step %}

### Place Tripod/Base Station Assembly (Self Survey ONLY)

Place the tripod & base station assembly in the location that it will be positioned at for the duration of operation.&#x20;

The base station will perform a self survey to determine its location before transmitting corrections data.&#x20;

{% hint style="info" %}
Moving the base station after it has been powered on will affect the geolocation accuracy.&#x20;
{% endhint %}
{% endstep %}

{% step %}

### Power On Base Station

Use the USB-A to USB-C cable to connect the power bank to the RTK base station. The base station will power on once connected.   &#x20;

## Software Setup

The Sentera base station is pre-configured to perform a self survey after power up to determine its geolocation.&#x20;

The self survey period is 120 samples (or 120 seconds) after achieving a 3D fix. For the survey to be valid an average accuracy threshold of 5m  must be achieved.&#x20;

This setup can be modified from the base station user interface.&#x20;

### Set Up & Power On Base Station

Use the directions above to set up and power on the base station.&#x20;
{% endstep %}

### Power on & Connect the PHX CommsBox

{% hint style="warning" %}
Look if you made it this far, this is where I got lazy and made life a little easier for us all. In the base station box there is a PHX commsbox. This is useful because it runs a DHCP server and allows us to skip setting up static IP ports/addresses. This is something I wouldn't do for customers because it's a ton of extra cost for something relatively silly and could be accomplished more elegantly and cost effectively.&#x20;
{% endhint %}

Power the PHX commsbox on using the USB-A to USB-B cable provided in the case. The commsbox uses the same kind of battery bank as a power source.&#x20;

Then connect the commsbox to the base station using an RJ45 to RJ45 Ethernet cable.&#x20;

{% endstep %}

{% step %}

### Connect To the Commsbox

Connect to the Comms Box WIFI network. It is named "PhoenixCommsBox\_SerialNumber", the network name for your Comms Box will include the serial number found on the comms box (ie PhoenixCommsBox\_0074).&#x20;

<figure><img src="/files/m15rSqoFWEa08N3g6RCI" alt="" width="282"><figcaption></figcaption></figure>

The CommsBox password is the serial number twice. In this example the CommsBox was serial number 0074, so the password is 00740074.
{% endstep %}

### Access Base Station Webpage

Access the base station web page by navigating to <http://192.168.143.31> in a web browser (no internet required)

## Sentera Base Station Radio

There is an integrated radio in the Sentera base station. This radio is not field programmable. This means that the radio needs to be programmed to match the radio in the module before hand.&#x20;
