Appendix E. Pair Connection
The pair connection function usually needs two the same CAN Converter modules. For example,
when these two I-7530s are in pair connection mode, all RS-232 commands transmitted from
one of these two I-7530s will be put in the data field of CAN message. This CAN message will be
transferred to RS-232 commands by another I-7530. 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 large to communicate by using RS-232.
Note:
All of CAN Converter modules, such as I-7530, I-7530-FT, I-7530A, I-7565, tM-7530,
tM-7530A ,and tM-7565, have pair connection function.
Using I-7565 with pair connection mode, it just supports RS-232 baud rate 115200 bps or less.
Configurations:
To apply this application, user need to configure the CAN Converter modules #1 and #2 as
follows. The RS-232 configurations of CAN Converter modules #1 and #2 are decided by the
Device1 and Device2 RS-232 parameters.
module #1 Configuration
module #2 Configuration
Communication Descriptions:
For example, if there are 7 bytes data, “1234567”, transmitted from Device1 which is sent CAN
