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.
Figure 3-23: The diagram of Application 2.
Configurations:
To apply this application, user need to configure the I-7530A-MR-
FD#1 and I-7530A-MR-FD#2 as follows. The RS-232 configurations of
the I-7530A-MR-FD#1 and I-7530A-MR-FD#2 are decided by the Device1
and Device2 RS-232 parameters.
I-7530A-MR-FD#1 Configuration
Communication Descriptions:
The communication of this condition is similar with the communication
of condition 1. The difference is that the I-7530A-MR-FD#2 of the
application 1 will transfer the RS-232 commands to Device2 immediately
if it receives any CAN message from the I-7530A-MR-FD#1. The I-7530A-
MR-FD#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 the Device1 sends 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. 256 bytes data at the same time).
