What Should I Do If I Have Not Received the Whitelist? How Can I Obtain and Import It?
Please refer to the “Upload Whitelist” section under V2Xcast SDK in the Unex Software Development Guide (SDG) for full details
Have Unex Products Obtained Any Certifications or Participated in Interoperability Testing?
For detailed certification information, please consult the Product Development Department.
- OA Certification: Please refer to the official Unex OA certificate. Additional details are available on the OA official website.
- Interoperability Testing: Unex participated in DSRC testing in earlier years and has more recently joined TPF testing. European standard (EU) testing has not yet been conducted.
How to Find Your MAC Address
A MAC Address (Media Access Control Address) is a unique identifier for every V2X device, required for add-on purchases, technical support, repair services, and warranty inquiries.
This 12-character alphanumeric code is typically printed on the device label, with location varying by product.
You can also use software to look up the MAC address, a method applicable to all of Unex's connected vehicle (V2X) products.
V2X Indoor Testing
With DSRC radio, the POTI service provides a configured position for testing without the GNSS signal. You can upload the POTI configuration file through v2xcast_manager.
Due to the CV2X PC5 radio being based on 3GPP RF requirements which need highly accurate timing synchronization, the CV2X devices cannot send and receive messages without any GNSS signal. In our experience, most of our customers including ourselves use GNSS repeaters for indoor testing.
V2X for video streaming
Video streaming based on V2X technology is possible, but not very feasible in the open field.
The V2X protocol is mainly designed for sharing the status of vehicles and emergency road events; basically, there should not be any station that bursts packets or occupies most of the bandwidth.

Trade Information for Unex’s V2X system
Understanding the ECCN, CCATS, and HS Code is essential for managing import procedures and tariff regulations for Unex's V2X wireless devices.
Use these codes as a reference to ensure smooth compliance with international trade and customs requirements for Unex V2X products.
V2X Deployment
Utilizing an ecosystem is critical to accelerating V2X innovations and fostering long-term mutual success. Unlike closed turnkey solutions, the V2Xcast® ecosystem provides a jump-start and open V2X experience, allowing you to customize and enhance your V2X applications as requirements evolve.
OBU: in-vehicle network through Ethernet(e.g., CAN)
To effectively collect data from the in-vehicle network after connecting the OBU to the Vehicle PC through Ethernet, you will rely on the current CAN interface and the SDK provided by your main system.

OBU series: Power Input Compliance
The power input of the OBU series is designed to comply with both ISO 7637-2 and ISO 16750-2 standards. These standards ensure the proper functioning and performance of the power input for the OBU series.
Consequently, product specifications may be subject to change over time. To obtain the most accurate and current information regarding compliance with ISO 7637-2 and ISO 16750-2 standards, it is advisable to contact our sales team for confirmation.
Inter-subsystem: Latency Cause (Ethernet or USB/mPCIe)
The latency caused by connecting subsystems via Ethernet or USB/mPCIe can vary depending on the hardware, network, and software used.
These latency figures are generalizations and can vary based on the specific hardware, software, and network configurations in a given system. Additionally, network congestion, packet loss, and other factors can also impact latency. It's recommended to test and benchmark the latency in your specific setup to obtain accurate measurements.

Relating V2Xcast® Fee
V2Xcast® is a comprehensive solution embedded in Unex's V2X devices and offered as a bundled package for Proof of Concept (PoC) projects or market deployments.
The package includes: Usage rights for Unex's Workshop Communication Stack, V2Xcast® technology, Software development tools, Software usage agreement.
12-month hardware warranty, Free software updates, Technical support.
Security: Certificates, Encryption, and Signature
In the current V2X environment, many applications are designed with the purpose of sharing status messages with nearby vehicles, such as vehicle position, speed, direction, and more. Encrypting these messages may prevent the receiving party from accessing the necessary critical information, thus impacting the normal operation of the entire V2X system.

Proprietary Message Usage in the SAE J2735
To achieve seamless integration of your proprietary message encoder and decoder with the V2Xcast® SDK, you need to ensure that the proprietary messages and standard ones are assigned different PSIDs (Provider Service Identifiers). PSIDs serve as unique identifiers for different message types within a specific channel.
By assigning different PSIDs to your proprietary messages, you ensure that they are distinguishable from the standard messages in the V2X communication. This way, when receiving or decoding messages, the V2Xcast® SDK can properly handle and route them based on their PSIDs.
