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.

Node: If users would like to run the CAN converter in the transparent or pair connection
application. Set the CAN converter to the Pair Connection Mode. Please refer to the
section 3.1 for the details of the Mode configuration.

interface at the same time. That is to say that the full-duplex communication mode of
RS-232 devices is not supported.

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/tM-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/tM-7530A also has
isolator on the CAN side.

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

The pin assignments of the CAN port (DB9 male) on the I-7530 series including I-7530, I-7530T,
I-7530-FT, I-7530A, and I-7565 follows both the CANopen DS102 profile and the appendix C of
the DeviceNet specifications. The wire connections are as follows.

The tM-7530 uses spring type connector on the CAN interface. The wire connection to the
tM-7530 is below.

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.
