PXI/ PCI 61xx – User Manual
The
PXI/ PCI 61xx
controller board has two extension sockets on the
top side prepared to take on a FlexRay plug-in Extension board
(see Figure 3-3, Figure 3-4). Each board has an independent FlexRay
controller and two FlexRay transceivers, providing full dual channel
functionality.
For a
PXI/ PCI 61xx
Controller board with
CAN Extension Board
,
only one FlexRay Extension board can be plugged in.
Each FlexRay plug-in module provides the following features:
♦
FlexRay controller (Freescale MFR4310)
♦
FlexRay 2.1 protocol compliant
♦
supports FlexRay transmission rates of 10, 8, 5 and 2.5Mbit/s
♦
2 FlexRay transceivers (NXP TJA 1080)
♦
wake-up detection
♦
switchable termination resistors
♦
full galvanic isolation
♦
isolated power supply of transceivers
The following table shows the main characteristics of the FlexRay
module:

Notes on R

:
The 100Ω bus terminating resistor can be deactivated by software
(G-API command
G_FlexRay_Node_BusTermination_Disable
,
activation anew by
G_FlexRay_Node_BusTermination_Enable
).
When configured with two FlexRay modules, both FlexRay modules
can be used jointly to startup a FlexRay cluster. In this case one node
will be the leading cold starter and the other one the following cold
starter.
In cases where the ECU under test is a cold start node itself a single
module could start up the cluster. This way the second module could
be used to operate a second FlexRay cluster independently.
