1. Introduction
CAN (Controller Area Network) bus is a serial communication interface, which is
highly fault-tolerant even in harsh environments with noise. Therefore, there is often a
need in the industry to convert interfaces such as RS-232, RS-485, RS-422 or USB to
CAN interface for communication, so CAN converters are developed. For example,
when the original equipment with RS-232, RS-485, RS-422 or USB interface (referred to
as UART side, such as PC, I-8000, WinPAC-8000…etc) needs to control or monitor
other new CAN interface equipment (referred to as CAN side), the electrical signal and
data can be converted through the CAN converter, the data of the UART side device
can be transferred to the CAN side device, or the data of the CAN side device can be
transferred to the UART side device.
In addition, the CAN converter supports three communication modes with normal
mode, pair connection mode and listen only mode. Among them, the pair connection
mode has a function similar to transparent transmission, which can transparently
transmit the data from one side to the other side.
The application architecture of the communication mode is shown in the below
figure. For details, please refer to Section 1.2.

1.2 Communication Mode Description
The CAN converter supports three communication modes with Normal mode, Pair
connection mode and Listen only mode as below descripption. In addition, please refer
to section 3.4 for the setting method of the communication mode. If you need to use the
COM port software during the test, please refer to section 5.7.
1.2.1 Normal mode
After inputting a fixed-format "UART command string" from the UART side of the
CAN converter, the CAN converter will respond whether the command is valid. If the
command is valid, it will output the data to the CAN side, but if the command is invalid,
it will not act. Conversely, when data be inputed from the CAN side of the CAN
converter, the CAN converter will also output a fixed-format "UART command string" to
the UART side as below figure. For the detailed command format, please refer to the
UART command string table in chapter 4.

In addition, if the customer only needs to exchange CAN messages with the CAN
device through the CAN converter (for example: I-7530), and does not need to know the
UART command string on the UART side, the VxCAN Utility can be used to achieve this
requirement.
The test interface of VxCAN Utility can convert UART command strings into CAN
messages as below figure, and the used mathod of test interface in VxCAN Utility,
please refer to section 3.6.

1.2.2 Pair Connection mode
As the name suggests, this mode is designed to use two CAN converters for pair
connection. The main purpose will transfer the interface from UART to CAN, and then
transfer again the interface from CAN to UART, so that the interface conversion effect
can be achieved without modifying the program of the field device as below figure .
In addition, if only one CAN converter (for example: I-7530) uses this mode, the
effect will be similar to the function of transparent transmission. The data be inputed
from the UART side of the CAN converter will be directly output to the CAN message as
below figure.

1.2.3 Listen only mode
This mode only supports tM-7530, tM-7530A and tM-7565, and be used to monitor
the messages of the CAN network without converting the message, so it will not send
any CAN messages to the CAN network, such as Error Frame or ACK signal.
For example, there are two CAN devices (such as I-7530 and I-7565-H2) in the
communicating, and the user want to obtain CAN messages between CAN devices, the
user can set the tM-7565 to listen only modee, and then connect the CAN side into the
CAN network, and connect the UART side to the PC for monitoring.
If the user uses a common communication port (COM port) testing software to
monitor in the PC as shown in figure 1.2.3.1, and will get the UART command string.
If the user uses the testing interface of VxCAN Utility to monitor in the PC as
shown in figure 1.2.3.2, and will get CAN messages.
Among them, if the user need to use the COM port testing software, please refer to
section 5.7. If the user need to use the testing interface of VxCAN Utility, please refer to
section 3.6.
