＊ Add Checksum: Set the CAN converters to enable or
disable
communication. If enable the checksum function, all UART
strings from / to the tM-7530 must append two bytes of the
checksum information. For checksum algorithm,
refer to the Node in the page 33.
＊ Error Response: Set the CAN converters to enable or
disable the error response mechanism in the UART
communication. If enable the error response, the error
code will be replied when users use the wrong UART
command string to communicate with the CAN converters.
＊ Timestamp Response: Set the CAN converters to enable
or disable the timestamp response mechanism. If enable
the timestamp response, the timestamp of each CAN
message will be appended in the UART string when the
CAN message are output from the UART interface of the
CAN converter. This function may be invisible because it
is not supported by the selected CAN converters.
 CAN Configuration:
＊ CAN specification: Decide which CAN specification, CAN
2.0A (11-bits CAN ID) or CAN 2.0B (29-bits CAN ID), will
be implemented.
＊ CAN baud rate: Set the CAN baud rate. The CAN
converters support several kinds of standard baud, such as
10K, 20K, 50K, 125K, 250K, 500K, 800K, 1000K, and
83.3K bps. If these baud rates don't fit the users'
application, use user-defined CAN baud rate to configure
the special CAN bauds.
＊ User-defined CAN baud rate: If the user-defined CAN
baud rate is used, users need to fill the value of the baud
rate in the "Required Baud Rate" field and click the
"Calculated" button to calculate the real value. If the real
baud rate is not the same as the value in the "Required
Baud Rate" filed, it means that the required baud rate can't
be reached because of the hardware limitation. The closest
baud value will be implemented for instead.
