The PEAK-System PLIN-USB adapter connects a Windows® PC to LIN Network (ISO 17987) with 500V galvanic isolation. The adapter can be operated as a master or slave and complies to LIN (Local Interconnect Network) standards up to version 2.2. The adapter can be used with the free Windows PLIN-View Pro software, or by writing an application program using the supplied PLIN-API.

The PLIN-View PRO software allows for the viewing of incoming LIN messages, and with the use of LDF (LIN Description File), the messages can be displayed symbolically. LIN Messages can be sent out in either master or slave mode. The software accesses the LIN functionality of the PLIN-USB adapter, such as the on-board scheduler or automatic bit rate detection. Additional features include:

  • Administration and processing of schedule tables
  • Recording of LIN frames (trace)
  • Scripting to automate processing of messages


Multiple PLIN-USBs may be used on the same PC, in separate instances of the software. The PLIN-USBs are distinguished though the user assignment of a “hardware ID” that is permanently saved in adapter.
