Configurations:

In order to apply this application, user need to configure the three CAN Converter modules #1,

#2 and #3, like I-7530 as above figure. The RS-232 configurations of these three CAN Converter

modules are decided by the RS-232 device they connect with.

module #1 Configuration

module #2 Configuration

module #3 Configuration

Communication Descriptions:

When Device1 would like to transmit RS-232 commands "1234567" to Device2, the commands

written to I-7530#1 by Device1 need to be "0021234567" because the Device1 is set to dynamic

Tx CAN ID (Fixed Tx CAN ID is not checked). The first three bytes of "0021234567" is "002", it

means that the CAN ID is 0x002 when the I-7530#1 receives the RS-232 commands from

Device1 and transfers it to CAN message. Afterwards, this CAN message is only accepted by

Device2 because the configurations of acceptance code and acceptance mask of Device2.

Similarly, if Device1 wants to send RS-232 commands "1234567" to Device3, it needs to send

"0031234567" RS-232 commands to I-7530#1. When the Device2 or Device3 respond the

RS-232 commands "456789", the CAN message will have CAN ID "0x002" and "0x003" because

of the configurations of Fixed Tx CAN ID of I-7530#2 and I-7530#3. Because the I-7530#1 is

set to Response with CAN ID, the Device1 will receive the RS-232 commands "002456789" or
