2. Introduction and Overview

2.1. Introduction

Thank you for purchasing a RAD-Moon Duo from Intrepid Control Systems (ICS). The RAD-Moon Duo is a Dual media converter for connecting to two port of 100BASE-T1 physical layer to two port of a 4-wire 10/100 Ethernet (100BaseTX). With its low cost, compact size and high performance, the RAD-Moon Duo is ideal for monitoring, analysis, diagnostics and other applications in an Automotive Ethernet environment.

Here are some of the noteworthy features of the RAD-Moon Duo:

2.1.1. Primary Features

  • Dual 100BASE-T1/TX media converters using the Marvell 88Q1010 PHY

  • Full-duplex support for simultaneous data transmission and reception across both PHY pairs

  • Automatic or static master/slave PHY configuration

  • Configure and monitor PHY registers via USB 2 (480 Mbp/s)

  • Network Interface Mode for logging with precision time stamps, scripting, and simulation.

  • Status LEDs show PHY and network status

  • Membrane buttons allow changing PHY operational modes

  • Isolated USB connection protects PC from potential damage.

  • Compact design: ~100 x ~65 x ~35 mm

  • Light weight: < 5 oz. (140g)

  • Rugged aluminum enclosure with rubber bumpers for durability

  • NanoMQS connection systems for Automotive Ethernet connection

2.2. Operational Overview

As you can see from the block diagram below, the RAD-Moon Duo can be configured for different modes of operation.

2.2.1. Dual Media Converter

In this mode, each of the 100BASE-T1 PHYs are connected to a 100BASE-TX PHY creating two independent media converters. Whenever any data is received on one PHY, it is automatically sent out on the other connected PHY, creating a seamless link between the two attached devices. Each of these media converters support full duplex, so data can be sent in both directions simultaneously.

2.2.2. 100BASE-T1 Network Interface

The primary function of this device is a dual media converter, but in this mode the 100BASE-T1 PHY connected to physical port “AE2” is connected to the CoreMini Processor which connects to a PC over USB. This allows the PC to monitor live network activity as well as transmit Ethernet frames. The received network traffic arrives to the PC with a precision time stamp for data acquisition. Transmit and receive functions can be accessed using Vehicle Spy software our the Open Source API. For more information on how to use Vehicle Spy with this feature, reference Core Features

In this mode, the function of the PHYs between AE1 and ETH1 remains unchanged.

Note

In this mode, the RAD-Moon Duo will not enumerate as a network adapter in the host PC’s operating system. Vehicle Spy or the Intrepid’s Open Source API must be used to access the 100BASE-T1 network. Reference Software Setup for more information.

2.2.3. PHY Register access

In any mode, each PHY can be accessed by the embedded processor over MDIO in order to read and write configurations registers. More infomation can be found in PHY Dashboard

2.2.4. Simulation and Scripting

Using Vehicle Spy you can define transmit messages with custom data and send them manually or on a schedule of your choosing. You can also write intelligent scripts that implement arbitrary logic and compile them into embedded scripts which can run within the device itself. This functionality allows you to create specialized test scenarios, and to simulate ECUs and gateways. More information can be found in CoreMini Scripting

2.3. Package Contents

Your RAD-Moon Duo package includes both hardware and software. Upon receipt, please remove, unwrap and inspect all its contents. If anything is missing or damaged, please contact Intrepid for prompt assistance, using the information at the end of this guide.

2.3.1. Hardware

Your RAD-Moon Duo package includes the following:

  • The RAD-Moon Duo Device

  • 2x standard 8-wire Ethernet cable (CAT5e)

  • Nano-MQS Connector and Terminal kit

  • A standard USB Type B to Type C SuperSpeed cable

2.3.2. Software

Unless physical media was specifically requested, your box should contain a reference card with instructions on where to download the device drivers and any other purchased software. If your media or reference card cannot be located, please contact Customer Support.

2.4. Hardware Requirements

2.4.1. Device Power

The RAD-Moon Duo is powered via the USB Type C connector. While this is typically a 5V supply, the RAD-Moon Duo is designed to withstand the automotive voltage range and electrical environment.

2.4.2. Computer Interface

As a hardware device, there are no specific requirements on the computer aside from the proper USB interface and the proper device driver installed. Instructions on installing the device driver are covered later with the installation of software.

Connection to a computer is needed both for configuration of the tool as well as to communicate with the device if you intend to use Vehicle Spy or Intrepid’s available API.
