USB-T1L

Technologies
  • USB 2.0
  • Linux 5.19
  • 10 Base-T1L Ethernet

The USB-T1L is a development tool for the relatively recent 10Base-T1l ethernet standard, which is intended to become a major building block in upcoming industrial ethernet products.

10Base-T1L has a couple of benefits, among which are the reduced wiring complexity, due to T1L only requiring a single pair of twisted wires, low power requirements and the possibility of very long cable runs of up to 2km. The tradeoff 10Base-T1L does for these great benefits is the relatively low maxium data rate of 10Mbit/s.

Features
  • Firmware free
  • Fault detection
  • Cable diagnostics
  • Up to 2 km cable reach
  • Linux Mainline Kernel Support
  • Low-Level Phy Register Access

There are currently two competing standards when it comes to industrial ethernet T1L connectors. In order to be neutral, the T1L comes with a screw terminal to connect the 10Base-T1L cable pair to.

The USB-T1L is built in a way, that gives the Linux kernel complete and native access to the registers of the 10Base-T1L phy. This means that the USB-T1L does not require any firmware on the device or vendor software on the host. All aspects of the phy can be controlled using standard Linux tools.
