GSM Outdoors 100BASE-T1 to 100BASE-TX Media Converter 2 in 1 Accessory

SKU CH-GXNQ-K313K

Converts automotive 100BASE-T1 BroadR-Reach to standard 100BASE-TX Fast Ethernet with plug-and-play operation and no latency or packet loss

  • Converts automotive 100BASE-T1 to standard 100BASE-TX Fast Ethernet
  • Includes UTP cable and 12 V power adapter for immediate use
  • BCM89811 PHY delivers zero-latency, loss-free signal conversion
  • Master/Slave configuration with link LED simplifies diagnostics
  • Driver-free plug-and-play operation saves setup time

Automotive Ethernet Media Converter

This converter bridges automotive ECUs running 100BASE-T1 BroadR-Reach at 100 Mbit/s full duplex to standard Fast Ethernet 100BASE-TX devices with RJ45 connectors. It targets engineers and technicians who need a direct point-to-point link for testing or integration without driver installation.

Check Power and Cable Requirements

Verify that your setup can accept a 12 V power adapter and that the single unshielded twisted pair cable included matches your 100BASE-T1 wiring. The unit operates as a plug-and-play device with no software drivers required for the conversion.

Replaces Custom Test Harnesses

It replaces ad-hoc converter boards or prototype harnesses used to connect automotive Ethernet to lab equipment. The jump is worth it when you need a reliable, latency-free bridge with master or slave configuration and link LED status for repeatable validation.

Questions about this item

What cables and power supply are included with the 100BASE-T1 to 100BASE-TX converter?

The package includes one unshielded twisted pair cable and one 12 V power adapter so the unit works immediately.

Which mode should I select on the 100BASE-T1 side, Master or Slave?

Use Master when the converter connects directly to an ECU that expects a Slave, and choose Slave when linking to a Master device; the link LED confirms the handshake.

What does the 100 Mbit/s full-duplex rating mean for latency when the converter is installed in a test bench?

The BCM89811 PHY processes frames without buffering delays, so the link adds no measurable latency and drops no packets during automotive Ethernet validation.
