お客様の RDDRONE-T1ADAPT: Ethernet media converter
1. Out of the Box
The NXP analog product development boards provide an easy-to-use platform for evaluating NXP products. The boards support a range of analog, mixed-signal and power solutions. They incorporate monolithic integrated circuits and system-in-package devices that use proven high-volume technology. NXP products offer longer battery life, a smaller form factor, reduced component counts, lower cost, and improved performance in powering state-of-the-art systems.
This page will guide you through the process of setting up and using the RDDRONET1ADAPT evaluation board.
1.1 Kit Contents/Packing List
The RDDRONE-T1ADAPT contents include:
- Assembled and tested media converter
- 1 x 2-wire T1 Ethernet cable with JST-GH connector
- 1 x 3-pin (2-wire) power cord with JST-GH connector
- Quick Start Guide
1.2 Additional Hardware
In order to function, the T1ADAPT media converter needs to be powered from 5.0 V via USB or 3 pin input connector, and that the Ethernet interfaces are connected. The polarity of the T1 cables is automatically detected and corrected if applicable.
1.3 Software
The board is preprogrammed and designed for plug-and-play operation. The binary file is provided on nxp.com and the source code is available on request.
1.4 User Manual
Refer to UM11602, RDDRONE-T1ADAPT evaluation board for additional details on the featured components and board configuration.

- DroneCode JST-GH connector or pin header
- Supports simple connector schemes
2.2 Board Description
The RDDRONE-T1ADAPT Ethernet adapter board is an evaluation platform for automotive 100BASE-T1 Ethernet. It can be used to connect a standard 100BASE-TX Ethernet device, such as a PC or single-board computer, to a peripheral device with a T1 Ethernet interface. Two RDDRONE-T1ADAPT boards can be used to connect two standard Ethernet devices together via a T1 network.
Software source code is available on request if the user wants to modify the configuration. However, the board is designed for plug-and-play out of the box with no additional software needed.
2.3 Board Components
| Label | Name | Description |
|---|---|---|
| 1 | TJA1101 | The TJA1101 100BAE-T1 automotive Ethernet PHY from NXP Semiconductors is used to support the T1 side of the media converter |
| 2 | 100BASE-TX PHY | The third party 10/100BASE-TX Ethernet PHY supports the standard Ethernet side of the media converter |
| 3 | LPC812 | The ARM Cortex-M0 micro is used to configure the two back-to-back PHYs and to control the master/slave behavior of the TJA1101 |
| 4 | Debug connector | This debug interface can be used to program the device. Since a physical connector is not mounted on the board, a cable such as the TC2050-ID-NL can be used to interface with the board via the debug interface. |
3. Configure Hardware
The RDDRONE-T1ADAPT board is designed to interface between standard 100BASETX Ethernet and two-wire automotive Ethernet in order to evaluate T1 performance. A number of configuration options are possible.
3.1 Evaluate T1 Between Two 100BASE-TX Devices
A pair of RDDRONE-T1 boards are used to connect two standard PCs with RJ45 connectors together over a 2-wire T1 network. The adaptors communicate with each other via T1 and the power is supplied by the PCs over USB cables.
3.2 Evaluate Communication Between a TX and a T1 Device
An RDDRONE-T1ADAPT is used to connect a PC or single-board computer to a T1 peripheral. In this configuration, the power may be supplied through the 3-pin JST-GH connector with 5.0 V power coming from a pin header or matching connector on the single-board computer.
3.3 Connect a 100BASE-TX Device to a T1 Network Switch
Connect a 100BASE-TX device to a T1 network switch.
