2 Self-reception. A frame transmitted from
the SDM-CAN that was acknowledged
by an external node will also be received
by the SDM-CAN but no retransmission
will occur in the event of loss of
arbitration or error. Frames received
correctly from an external node are
acknowledged.
3 Normal, retransmission will occur in the
event of loss of arbitration or error.
Frames received correctly from an
external node are acknowledged. This is
the typical setting to use if the SDM-
CAN is to be used to transmit data.
4 Transmit once; self-test. The SDM-CAN
will perform a successful transmission
even if there is no acknowledgement
from an external CAN node. Frames
received correctly from an external node
are acknowledged.
5 Self-reception; self -test. The SDM-CAN
will perform a successful transmission
even if there is no acknowledgement
from an external CAN node. Frames
received correctly from an external node
are acknowledged. SDM-CAN will
receive its own transmission.
6 Normal; self-test. The SDM-CAN will
perform a successful transmission even if
there is no acknowledgement from an
external CAN node. Frames received
correctly from an external node are
acknowledged.
7 Not defined.
8 Not defined.
9 Leave switch setting unchanged.
33 Read SDM-CAN's internal switches. Place results in the array
specified in the Dest parameter.
StartBit
The StartBit parameter is used to identify the least significant bit of the data
value within the CAN data frame to which the instruction relates. The bit
number can range from 1 to 64 (there are 64 bits in a CAN data frame). The
SDM-CAN adheres to the ISO standard where the least significant bit is
referenced to the right most bit of the data frame. If a negative value is
entered, the least significant bit is referenced to the left most bit of the data
frame.
