Quick Start User Guide
1. Introduction
This manual introduces the user to the methods used to implement
the I-7530 module into their applications in a quick and easy way. This will
only provide with the basic instructions. For more detailed information,
please refer to the I-7530 user manual located on the ICPDAS CD-ROM
or download it from the ICPDAS web site:
http://www.icpdas.com/products/Remote_IO/can_bus/i-7530.htm
The goal of this manual is focused on helping users to quickly
familiarize themselves with the I-7530 module and the RS-232/CAN
communication converter. Here, we use two I-7530 modules (called the I-
7530 A and the I-7530 B) as the example will demonstrate how to use the
I-7530 modules. The architecture of this example is depicted below.
When the I-7530 receives a valid RS-232 message with the ASCII
strings format, it converts this RS-232 message into a CAN message and
transmits it into the CAN network. Based on the same reasoning, when a
CAN message is received via the I-7530, the message will be transferred
to a RS-232 message by using the ASCII strings format through the RS-
232 port.

2. Hardware Installation
Users need to make a hardware connection between the CAN
devices before the application. The details of this are illustrated below:
Step1: Set-up the 120Ωterminator resistor of module A and B.
Before you continue, if you have changed the settings from default
then it is necessary to open the cover for each I-7530 and re-configure
their JP3 jumpers to enable them again, as shown in below figure.
However if the I-7530’s still have their default settings then it is not
necessary to open and reset them because the default configuration is
enabled.

Step2: Power connection for the I-7530 A and B
Connect the (R)+Vs and (B)GND pins of the I-7530 module to the DC
power supply (10~30VDC).

Step3: RS-232 connection
Connect the RS-232 ports of the I-7530 A and I-7530 B to the RS-232
COM1 and COM2 on the PC respectively.
Step4: CAN bus connection
Connect the CAN ports of these two I-7530 modules using the
following structure.
3. The I-7530 Parameters Configuration
Before starting the I-7530 converter tests, users need to configure the
RS-232 & CAN parameters via the I-7530 Utility tool. The details of this
procedure are shown below.
Step1: Turn off the DC power connected with these two I-7530 modules.
Step2: Set the Init/Normal switches on the back of the I-7530 A to the
“Init” position. Then, turn on the DC power. The ON LED of the I-
7530 A will be flash approximately once per second. That means
that the I-7530 is in the configuration mode.
Step3: Run the I-7530 Utility. The “I7530.exe” is located in the

I-7530 RS-232/CAN Converter Quick Start User Guide (Version 2.0, Sep/2007, I-7530) ------ 4
can_cd\can\converter\i-7530\ folder on the companion CD-ROM or
can be downloaded from the web site:
http://www.icpdas.com/download/can/index.htm
Step4: Click the “Connect” icon to select the PC COM port and Baud rate,
which are used to connect with the I-7530 A. The default setting of
the PC COM port is configured at 115200bps, 8 Data Bits, 1 Stop
bit, no parity and no Checksum automatically. The steps are
shown in the following figure.

Step5: Click the “Ok” button. If this process is successful, the I-7530 Utility
shows the I-7530 A communication information as below.

Step6: In order to match the RS-232 parameters on the PC COM port,
please configure the RS-232 parameters of the I-7530 A as follows:
Baud rate : 115200bps
Data bits : 8
Stop bits : 1
Parity : None
Checksum : No
Step7: Set the CAN baud rate of the I-7530 A. Here, use 125K bps for
CAN baud, and uncheck the pair connection (For more information
about pair connection, please refer to user manual section 3.4).
Step8: Click the “Setting” button to save these CAN/RS-232 parameters
into the EEPROM of the I-7530 A.
Step9: Repeat Steps 1 to 8 to configure the I-7530 B converter with the
same parameter settings as the I-7530 A.

4. Testing the I-7530s by using the I-7530 Utility
Step1: Turn off the DC power connected with these two I-7530 modules.
Step2: Set the Init/Normal switches on the back of the I-7530 A and I-
7530 B to the “Normal” position. Then, turn on the DC power. The
ON LED of the I-7530 A and B will always be turned on. It means
these two I-7530 converters are working in the operation mode.
Step3: Run the I-7530 Utility, I7530.exe, two times. Then duplicate I-7530
windows will be displayed on the screen. One is named as Utility A
and the other is called Utility B.
Step4: Select the “Test” tab and click the “Connect” icon on the tool bar of
Utility A and Utility B to configure the RS-232 COM1 and the RS-
232 COM2 on the PC. The COM1 and COM2 ports on the PC will
be used for connecting with the I-7530 A and B converters,
respectively.
Step5: After selecting the necessary Com port and baud rate, click the
“Ok” button on Utility A and B, respectively. Then, Utility A is
shown in the below figure and Utility B will be similar to Utility A.
Step8: Check the “Use CAN Message” checkbox and input the value to
the “CAN Message” frame on Utility A. Click the “Send” button.

Then, the Utility will automatically transfer these CAN messages to
the RS-232 command string with ASCII 0x0d, and send it out
through the PC RS-232 COM1 port. After the I-7530 A receives
this command. It will transfer the RS-232 message to the CAN
message. So, the I-7530 B will receive the CAN message
transmitted from I-7530 A. Then, convert this CAN message to the
RS-232 message and send it out to the COM2 port on the PC.
Detailed steps of this are shown in the following figure.
