GPX Stream - System Overview
Welcome to your GPX Stream system!
The following article will describe the GPX Stream system in detail.
This article is available as a video guide by clicking here or at the bottom of this page.
7GX Cube
The 7GX unit is the brains of the system. Also known as a video encoder, it receives video data over HDMI. Once the video is received, it prepares it for transmission over cellular networks.
Encoders work by taking raw video feeds from an HDMI or SDI cable, and converting them into what is known as packets.
During the conversion process, the encoder analyzes each of the 30 images per second of the video.
Based on its analysis, unnecessary image data is discarded (such as repeated pixels from one picture to the next), and only the most important information is kept in order to ensure the quickest and most efficient transmission possible over cellular networks.
Packets are then created to be of equal size, and depending of the video complexity, each packet can contain more or less images. These packets are then sent to the cellular modem, which transmits all of the information through LTE or 5G networks to our cloud servers.
Device description
The front of the 7GX provides information to the users to ensure the proper functioning of the device, such as status lights, and buttons to access the device menu and settings.
Generally, when you receive your GPX Stream system, there are rarely any actions required. The devices are shipped pre-configured, and ready to use.
However, you'll want to be aware of these features in case you need to change APN settings when travelling to a different region, or if our support team instructs you do navigate the menus to perform resets or other operations.
Front of 7GX
| On the left side of the screen - status lights | On the right side of the screen - buttons |
| Video - blue when an HDMI source is connected | Red - "Go Live" button, not used by GPX Stream as streams start automatically |
| Encoder - blue when receiving video and currently operating | Black - Menu and navigation button, can be used to scroll left, right, up, down, and pressed to select. |
| Cloud - blue when having an active connection and active stream | |
| Warning - red when there is a hardware problem with the device | |
| SD Card slot - not used by GPX Stream, as SD card recordings do not start automatically |

Node Modem
The Node modem is exclusively responsible for providing an internet connection to the system. It receives data and power through the single 4-pin LEMO to USB cable, and transmits the encoded video through the antenna (connected to the two antenna terminals) over cellular networks.
On the left side of the Node is a 4-pin LEMO connector. The power and data cable connects here, while the other end of the cable connects via USB to the top of the 7GX.
The right side of the Node is where you'll find the SIM Card slot.
The Node uses a full size SIM card, or a mini/nano SIM card with adapters.
To install a SIM card, simply unscrew the phillips-head screw and remove the small protection panel.
Exercise extreme caution when remove the screw and panel while the system is mounted inside a vehicle. Neither elements are magnetic, thus very easy to drop and lose within the vehicle. We recommend removing the Node from the vehicle before opening the SIM card slot.
The top of the Node has two antenna terminals.
If you have a single remote antenna with two cables, be mindful of the correct terminal connections. For all other antennas, the leads can be connected to either terminal
For the best possible network connection:
• The cable labeled LTE1 should be connected to the left side terminal, closest to the power light and the power terminal.
• The cable labeled LTE2 should be connected on the right side terminal, closest to the SIM card slot.
