Application 2:
This application architecture is the same as the one of application1.
The application architecture is show below. The difference will be
discussed in the following paragraph.
Configurations:
To apply this application, user need to configure the I-7530#1 and I-
7530#2 as follows. The RS-232 configurations of I-7530#1 and I-7530#2
are decided by the Device1 and Device2 RS-232 parameters.
I-7530#1 Configuration
Communication Descriptions:
The communication of this condition is similar with the communication
of condition 1. The difference is that the I-7530#2 of the application 1 will
transfer the RS-232 commands to Device2 immediately if it receives any
CAN message from the I-7530#1. The I-7530#2 of application 2 will not
transfer the RS-232 commands to Device2 until it has checked the end
character of RS-232 command (The end of RS-232 command is 'CR'). For
example, if Device1 send RS-232 commands "123456789", the Device2 in
application 1 will receive the data "12345678" immediately, and receive
the data "9" with a little delay. But, Device2 in application 2 will receive the
data "123456789" at the same time (Max. 72 bytes data at the same time).
