CANFDNET-400U
High-performance Four-channel CANFD Bus-to-Ethernet Converter User Manual
the frame information of CAN (CANFD) will not be converted.
Allow CAN frame flags to be forwarded into serial frames:
This parameter is
selected, the converter will add the frame ID of the CAN (CANFD) message before the
frame data of the serial frame and after the frame information (if frame information
conversion is allowed). When this parameter is not selected, the frame ID of CAN (CANFD)
is not converted.
Position of the CAN frame identifier in the serial frame:
This parameter is only used in transparent conversion with flags. When the serial port
data is converted into CAN (CANFD) messages, the offset address of the start byte of the
frame ID of the CAN (CANFD) message in the serial frame and the length of the frame ID
(see 4.2 Transparent Conversion with Flags).
[Note]: The frame ID length can be filled with 1 to 2 bytes in the standard frame,
corresponding to ID1 and ID0 of the CAN (CANFD) message respectively. When
extending the frame, 1 to 4 bytes of ID3, ID2, ID1 and ID0 can be filled.
The ID of the standard frame is 11 bits, and the ID of the extended frame is 29 bits.
Time interval (ms) between serial frames:
This parameter is used
with
flags. This parameter is the minimum time interval between two serial frames when
the user sends serial frames to the converter. The interval is in "milliseconds". The value is
0-500 ms.
[Note]: This time cannot be less than the time to transmit a single character;
otherwise, the repeater will be automatically set to an appropriate value (two characters of
time). The frame interval time sent by the user is preferably greater than the set time;
otherwise, the frame conversion may be incomplete.
The meaning of "time to transmit a single character" is: at the corresponding baud
rate, the time required for the serial port to transmit one character (10 bits); that is, divide
10 by the corresponding baud rate.
For example: at a baud rate of 9,600 bps, the "number of characters in the serial
frame interval" is 4, and the "time to transmit a single character (10 bits per character)" is
(10/9600)s,
the
obtained
(10/9600)*4=4.17(ms); that is, the time interval between two serial frames is at least 4.17
ms.
CAN frame forwarding interval (ms):
This parameter is valid in all modes. This parameter is the delay time between
forwarding CAN (CANFD) messages from the repeater.If this parameter is greater than 0,
