Note:
In the Slave mode, the 100BASET1_SPY will answer to a request, that has been sent by a
Master, without logging the information through the selected Gigabit Port in
Output to.
The payload,
length and ID for the slave response will be set through the Fast Ethernet Port in 100BASET1_SPY.
Lin Version
:
Allows to select LIN Version 1.3 or LIN Version 2.0. The difference between both modes
is the Checksum calculation method.
Bit Rate
:
Allows to select the LIN Bit Rate. Available options: 1200bps, 2400bps, 4800bps, 9600bps,
19200bps.
Note:
The device which is connected to this port must have the same Bit Rate and Version.
5.4.6.1
LIN Master Mode
In the LIN Master Mode, the 100BASET1_SPY LIN port acts as the Master in the LIN protocol commu-
nication. In this case, a specific Ethernet frame received from any of the Gigabit ports will be sent
through the LIN port. The following table shows the structure of the Ethernet LIN Master frame used
for this purpose:
Note:
In this mode, the devices connected to the 100BASET1_SPY LIN port must be configured as
Slave, with the same Bit rate and LIN version.
Note:
If the Length field is set to 0x00, the frame will be sent without data, corresponding in this case
with a LIN Master Request, according to LIN specification.
