# Connect to Rover

This tab configures the method upon which differential corrections are forwarded to rover. The following options and parameters must be configured to ensure that SpatialLightHouse properly connects to the rover.

## Connect to rover as a TCP client (Wi-Fi or ethernet)

This option allows you to connect SpatialLightHouse to the rover via TCP/IP by providing either the hostname or IP address of the rover. A connection can be established via an ethernet cable (using the hostname rover-wire) or by connecting to the rover via Wi-Fi (using the hostname rover-wifi).

## Provide differential corrections using a TCP server

This option allows rovers to connect to SpatialLightHouse via TCP/IP and have differential corrections transmitted to them. Rovers must connect to SpatialLightHouse via a user-specified TCP port (default port number is 1000) and wait for incoming connections. Once connected, SpatialLightHouse will transmit differential corrections to clients.

## Provide differential corrections on a serial port

In this configuration, SpatialLightHouse will send the differential corrections out on a (virtual) serial port. For example, data could be sent via a USB/serial converter to an external, high-power UHF modem.

## Connect to rover via Phoenix LiDAR Systems connection service

SpatialLightHouse will send differential corrections to the server defined in the settings dialog. This requires an internet connection, which is typically a cellular modem attached to the PC. If the rover also uses a cellular modem, it will connect to the same server and retrieve the corrections. The license key must be entered for the server to correctly associate reference station and rover.
