LIN Interface and Gateway
In many applications (in particular automotive) LIN is used as a low
cost, low performance, local data collection or control bus. This module
acts as a gateway between a CAN bus and a LIN bus.
A
software package is provided that can set up the PCAN-LIN in one of
a number of modes ( CAN to LIN, Serial to CAN, Serial to LIN).
The most useful of these is the CAN to LIN mode. Using it the
module acts as a LIN master and sends incoming CAN packets to LIN
and LIN to CAN ( with configurable offsets).
- PCAN-LIN is compliant with
the LIN
Protocol Specification Rev. 1.3 (power management functions such
as Sleep Mode and Wake Up Signal are however NOT implemented)
- LIN speed range 1000 Bits/sec to 20000
Bits/sec
- A user-definable LIN-ID list provides a simple
mechanism for scheduling a limited number of LIN messages to take
place cyclically.
- It may be used as a
general-purpose gateway
(or router when using Acceptance Code/Acceptance Mask feature)
- It may be used as LIN
slave or master/slave (no data conditioning takes place when handling a
scheduler list in LIN master mode)
- An option is available to
provide electrical decoupling between the RS232 and CAN/LIN (maximum 1
kV)
If you simply need an interface between
a PC and a LIN bus we recommend that one of the many PCAN interfaces
( parallel or USB) be used with the PCAN-LIN as a bus
converter. In this way full advantage may be taken of the free
software included with the interface to view the contents of the
bus and to control it from the PC.

There are 3 versions of the LIN gateway available......
- 2025 for which the CAN port operates as a standard 2.0B Full CAN using
the Philips 82C251 transceiver
- 2028 for which the CAN port uses the "slow CAN" and the
TJA1054 transceiver.
- 2029 with the Full CAN interface and an opto-isolator in the serial
port
