100Base-T1 Media Converter

MA-100BASET1-MC-ETH
New
$299.00

A bi-directional physical layer converter between 100BASE-T1 (OPEN Alliance BroadR-Reach – OABR) and 100BASE-TX (Fast Ethernet), enabling the user to easily connect automotive cameras or ECUs with OABR / Automotive Ethernet media link to a standard computer network.

The interface establishes a point-to-point link between an unshielded twisted-pair Automotive Ethernet (IEEE 100BASE-T1) port and a Fast Ethernet port. The converter features one DSUB9 (BroadR-Reach, CAN bus), one Fast Ethernet port with RJ-45 connector, and a Micro-USB connector. The BroadR-Reach channel is configurable as either Master or Slave by a switch button or programmatically, and the device can be powered either via DSUB connector or via USB.

The converter offers a possibility to access SMI registers of both transreceivers (PHYs) via a CAN bus or a USB’s virtual serial port. This enables the user to evaluate signal strength, detect polarity of the T1 port, carry out a BroadR-Reach media test to diagnose cable errors, fine-tune the PHYs parameters, and generally to read and write the registers.

A free-of-charge PC utility for our 100BASE-T1 Media Converter is available for download (in Download Links). The application shows the user the Media Converter’s status information including a signal quality of the 100BASE-T1 port. The utility can also start a 100BASE-T1 network cable test on converter and show the result (OK / Open-circuit / Shorted) to the user.

The 100BASE-T1 Media Converter is available as a serial port (COM port) when it is connected to a PC over USB. The PC application reads the following information out of the converter:

  • T1 port status
  • T1 port signal quality
  • Master/Slave configuration
  • T1 port polarity detection
  • RX and TX error counters
  • a result of T1 cable test (OK / Open-circuit / Shorted)
  • 100BASE-T1 (IEEE 802.3bw) to 100BASE-TX media conversion
  • Master/Slave configuration for BroadR-Reach
  • DSUB9 connector for T1, RJ-45 connector for Ethernet
  • Power 9-30 V DC over DSUB or Micro-USB connector
  • 6 status LEDs
  • 2 DIP switches
  • Automatic polarity detection for OABR Slave
  • Media test for T1 cable – can detect a shortage, cut-off and impedance mismatch
  • Table top or DIN-rail mount
