3.4 Pair-connection Mode Description

The pair connection function usually needs two I-7530A-MR-FDs.
When these two I-7530A-MR-FDs are in pair connection mode, all RS-
232/485/422 commands transmitted from one of these two I-7530A-MR-
FDs will be put in the data field of CAN message. This CAN message will
be transferred to RS-232/485/422 commands by another I-7530A-MR-FD.
The following section will show each condition for different pair
connection configuration.
Application 1:
This application may be used in two general RS-232 devices which
need to connect with each other, but the distance between is too long to
communicate by using RS-232.
Figure 3-22: The diagram of Application 1.
Configurations:
To apply this application, users 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.
