1. Introduction
CAN (Controller Area Network) is a serial bus control protocol
especially suited to structure intelligent industry devices networks and
build smart automatic control systems. By using the CAN Bus converters,
some programmable RS-232/RS-485/RS-422 or USB devices such as PC,
PAC or PLC, can be the master of a CAN network, and can control or
monitor the CAN devices via the CAN Bus converters.
In order to fit the market requirements, there are some functionalities
of the converters are expanded for some special applications. The
transparent mode is useful when the UART sensors or actuators need to
be a device of the CAN network. The pair connection mode helps the PC
to connect with other RS-232/RS-485/RS-422/USB devices via CAN Bus
for prompting the communication speeds or extending the communication
distance. The application architecture may be as follows.

2.3 Block Diagram
The I-7530/I-7530T and tM-7530 provide CAN and RS-232
communication interfaces. The isolator is on the CAN side. The connector
of the CAN port to the I-7530/I-7530T and tM-7530 are the D-Sub 9-pin
male connector and the spring type connector respectively.
Figure: The block diagram of the I-7530/I-7530T and tM-7530
The hardware profile of the I-7530-FT is the same as the I-7530/I-
7530T. The main difference between I-7530-FT and I-7530/I-7530T is
followed CAN specification. The I-7530-FT is ISO 11898-3 device, which
is also called low speed fault tolerance (LSFT) CAN device. There is no
isolator on the I-7530-FT.
Figure: The block diagram of the I-7530-FT
The I-7530A provides four communication interfaces in one module.
They are CAN, RS-232, RS-485 and RS-422 interfaces. Because the RS-
232, RS-485 and RS-422 are the same UART port, users can’t use them
at the same time. The I-7530A also has isolator on the CAN side.

The I-7565 provides CAN and USB slave communication interfaces.
On the USB interface, the I-7565 provides the virtual COM driver. Users
can use the I-7565 instead of the I-7530 if the device only have USB host
interface. The I-7565 is powered by the USB interface, it doesn’t need
external power. The isolator of the I-7565 is on the CAN side.

2.4 Wire Connection
The I-7530/I-7530T, I-7530-FT, and tM-7530 are RS-232 DCE devices,
and uses the D-sub 9 pins female connector for the RS-232 interface. The
following figure describes the wire connection between the PC and the
modules.
Figure: Connects the I-7530/I-7530T, I-7530-FT, or tM-7530 to the PC
The I-7530A has one UART port with three kinds of interfaces. The
following figure is the wire connection of the I-7530A to other UART
device. When users use the RS-485 or RS-422 interface, it is strongly
recommend to use twisted pair cable for the communication media.

2.5 Terminator resistor
According to the ISO 11898 specifications, the ISO 11898-2 CAN Bus
network must be terminated by two terminator resistors (120Ω) for proper
operation, as shown in the below figure. If there are not only two
terminator resistors or only have one terminator resistor on the CAN bus,
the CAN network may be malfunction. About the terminator resistor of the
I-7530-FT (follows the ISO 11898-3 specification), each I-7530-FT has its
own terminator resistor. Users don’t need to take care about that.
Figure: Terminator resistor for the ISO 11898-2 CAN network
If users would like to enable or disable the terminator resistor inside
the CAN converters, it is necessary to open the cover of the CAN
converters and use jumper to do that. Here are the descriptions of how to
enable or disable the terminator resistor of the CAN converters.

2.5.1 Init/Normal DIP-Switch
The Init/Normal DIP-Switch is used to set the module run in the
configuration mode or the operation mode. After users get the module, the
configuration generally needs to be done first. Here is the description
about the Configuration mode and the Operation mode.
Configuration mode: This mode is used to set the UART or CAN
communication parameters for baud rate, data format, filter, etc. After
finishing the configuration, all of the parameters will be stored in the
EEPROM of the CAN converters.
Operation mode: This mode is used to convert the UART data and
CAN messages with each other. Users can also use the UART
commands to get module information or change some configuration of
the UART or CAN parameters. Some of UART commands like “P2”
and “P3”for changing the configuration in the normal mode will not be
stored in the EEPROM. About the detail description, please refer to
chapter 4 Command List.
The DIP-switch position for different modules may be different. The
DIP-switch of the I-7530/I-7530T, I-7530-FT, I-7530A, and I-7565 are on
the back of the module, as following figure.
The DIP-switch of the tM-7530 is in the bottom of the module.

2.5.2 LED Indication
Except the I-7530A-MR, all of the CAN converters provide 2 LED
indicators. The ON LED is turned on when the module is running in
Operation mode. If the module is in Configuration mode, the ON LED is
flashed once per second. The ERR LED is used for indicating if the
module is going wrong or not. If there is no error happened, the ERR LED
is always turned off. If some error occurs, different CAN converters may
have different behavior of the ERR LED. When the ERR LED is turned on
or flashed, users can use the UART command string “S[CHK]<CR>” to get
the details about the error. If the error is happened due to the overflow of
the CAN or RS-232 software FIFO, users can use the UART command
string “C[CHK]<CR>” to clear the error, or users may need to reboot the
CAN converter for recovery.
The position and behavior of the LED indicators to the I-7530/I-7530T,
I-7530A, and I-7565 is as following figure.

3. Software Utility
This section guide you how to configure the CAN converters and test
them by using the VxCAN Utility. Users can free download the VxCAN
Utility from the ICP DAS web site or get it from the ICP DAS fieldbus CD
in the product package.
Download & CD-ROM path:
http://ftp.icpdas.com/pub/cd/fieldbus_cd/can/virtual_can/vxcan_utility/
CD:\fieldbus_cd\can\virtual_can\vxcan_utility\
The VxCAN Utility is based on the Virtual CAN technology which is
developed by the ICP DAS and is used to integrate the CAN interfaces of
the different CAN converters from the ICP DAS. All of the CAN interfaces
found by the PC will be sequentially mapping to the virtual CAN ports by
the Virtual CAN driver. Users just use the virtual CAN ports to develop
their application, and don’t need to know what kind of CAN converter they
use. It is very useful for transplanting the application to other platform with
different CAN devices. Besides, the VxCAN Utility also provides the
configuration interface for UART to CAN converters. Users can use this
tool to configure the CAN converter, test the CAN devices, monitor the
CAN network and analysis the CAN messages. For more information
about the VxCAN Utility, please refer to the website or the VxCAN Utility’s
manual :
http://www.icpdas.com/root/product/solutions/industrial_communicatio
n/fieldbus/can_bus/other/vxcan_driver.html
