Communication Descriptions:
If there are 7 bytes data, "1234567", transmitted from Device1, the
Device2 will also receive "1234567" from the COM port of I-7530A-MR-
FD#2.
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-FD#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-FD#2.
Note1:
If users use 115200bps for RS-232 port of I-7530A-MR-FD, it is
recommended that the configuration of the I-7530A-MR-FD 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-FD, 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-FD 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.
