ICP DAS USA I-7530A-MR User Manual page 38

The CAN ID in above figure is determined by the CAN specification
selected by users. If users select CAN 2.0A, the CAN ID is 11-bit ID. If
CAN 2.0B is used, the CAN ID is 29-bit ID. Here, assume users set the
Fixed Tx CAN ID field of I-7530A-MR#1 to be 0x001 ( "0x" is for
hexadecimal format) and CAN 2.0A is used, the CAN ID displayed in
above figure is 0x001.
If there are 9 bytes data, "123456789", transmitted from Device1, the
Device2 will also receive "123456789" from the COM port of the I-7530A-
MR#2.
Note1: If users use 115200bps for RS-232 port of I-7530A-MR, it is
recommended that the configuration of the I-7530A-MR CAN baud rate is
closed to the configuration of RS-232 baud rate, such as 125K bps. When
you use pair connection function of the I-7530A-MR, the baud rate under
125K bps is proper. (Max. 256 bytes data at the same time)
"CAN Timeout" and "UART Timeout" parameters are the timeout
Note2:
values for I-7530A-MR to check when to send message to the other side.
When receiving a message, the timeout will be refreshed. And when the
timeout reach to zero, message will be sent. The units of these two
values are micro-second.
