Part Number:M L120 USB-RETAIL
  • L120 Enclosed Logger USB (Part #L120 USB): Supplied with internal logging and USB logging already enabled.


Both L120 variants can be utilized in the following ways:

D Series Display Controller

An L120 can be used as a controller for a MoTeC D series Color Display. The L120 can forward all required channels for the driver to the D153 or D175 display, including lap timing, CAN/RS232 channels and much more.

CAN Bus Bridge

As standard, both L120 variants can be used to take messages from one CAN bus and pass it onto another. This is very useful when information needs to be shared but the two CAN buses are incompatible, such as different bus speeds.

T2 Telemetry Box

  • Requires optional T2 Telemetry upgrade 

With the T2 option enabled, the L120 can be used as a Telemetry box that receives information from other CAN devices, such as ECUs and Display Loggers. It converts this data to a T2 Telemetry stream and transmits it via radio to the corresponding T2 system in the pits. A T2 Telemetry box is particularly useful if there is no MoTeC Color Display in the vehicle to perform this task.

CAN and RS232 Logger

The L120 can be placed anywhere in the vehicle and used to log channels from both L120 CAN buses, as well as the RS232 bus. With only Power, CAN and RS232 connections, this is a simple, user-friendly logging solution.

Fully Featured Logger

  • #L120 requires optional upgrades I/O Enable and 120MB Logging
  • L120 USB #18045 requires optional upgrade I/O Enable

With the Input/Output (I/O) and Logging upgrades enabled as required, L120 Enclosed Loggers can log data from any CAN and RS232 bus, as well as inputs wired directly to the box. In this form, the L120 is a powerful logger that can be placed anywhere in the vehicle, ensuring weight and wiring is kept to a minimum.
