# Preparing the System

Follow this checklist to make the system ready for a successful mapping mission.

For all steps below, make sure the system is **NOT connected to a power supply**.

## GPS and WiFi Cables

* [ ] GPS antenna is connected to ANT1 port (for single antenna setups)
* [ ] GPS antennas are connected to both ANT1 and ANT2 (for dual antenna setups)
* [ ] WiFi antenna (if required) is connected to the WLAN port

{% hint style="info" %}
If you are not going to use Wi-Fi to connect to rover, you must install a Wi-Fi terminator on the Wi-Fi (WLAN) antenna port. Failure to install the Wi-Fi terminator on the Wi-Fi antenna port of the Nav Box when Wi-Fi is in use could destroy the Wi-Fi transmitter/receiver.
{% endhint %}

### Camera Cable

* [ ] Camera cable is securely connected to the 37-pin NavBox I/O connector (thumbscrews on the cable are properly tightened). This step is only required when your system makes use of a camera.

{% hint style="danger" %}
Never connect or disconnect the I/O cable or any attached sensors/cameras from the I/O connector while the unit is supplied with power. This can lead to substantial damages to both NavBox and attached sensors/cameras. Always shut down the unit completely and unplug the power supply before disconnecting the I/O connector. 
{% endhint %}

### Power Cable

* [ ] Power Splitter Cable is secured to the NavBox front panel via the safety thumbscrew
* [ ] Always first connect the Power Splitter Cable to the NavBox first, before connecting the battery/power supply. This will prevent sparking on the MR30 input connector of the NavBox.

### General

* [ ] Fan ventilation openings on the NavBox are not covered by objects or tape

Once all the points mentioned above have been verified, it is safe to proceed to the next section [Recording Data](https://docs.phoenixlidar.com/hardware-and-interfaces/navbox/scout/recording-data).
