3 Technical Description
G PCIe 6281
17
For Automotive Ethernet the following transceiver is used:
•
88Q2112 (100/ 1000MBit/s)
To use the Automotive Ethernet interfaces an Ethernet activation is necessary. This can be obtained
through the

3.5.5 Digital IO
The
G PCIe 6281
Multibus Controller supports a total of eight interfaces for Digital I/O. Of these four interfaces
can be used as a digital input and four as a digital output. These are firmly installed on the board.
The following specifications apply to the interfaces:

3.5.6 SENT
Optionally, up to two SENT inputs and four SENT outputs according to the SAE J2716 standard are available.
The Datalink Layer of the SENT Transmitter is implemented as programmable FPGA logic. The digital inputs (for
SENT Rx) or outputs (for SENT Tx) of the base board serve as a physical layer. This means that two of the four dig-
ital inputs can be routed to SENT Rx. Equivalently two of the four digital outputs can be reconfigured to SENT Tx.
The commands for controlling the SENT functionality can be found in the
G-API
documentation in
section
IO-Function
.
The SENT Interfaces are a license option for each device. An
of already delivered devices is
done via an activation code.
The SENT interfaces belong to the I/O interface. Therefore, they do not appear as separate interfaces
