I-7530A-MR Modbus RTU to CAN Converter Quick Start User Guide (Version 1.0, May/2011) ------ 6
Baud rate
: 115200bps
Data bits
: 8
Stop bits
: 1
Parity
: None
Checksum : No
Step8: Set the CAN baud rate of the I-7530A-MR_A. Here, use 125 kbps
for CAN baud, and uncheck the “Enable CAN Filter” item (For
more information about CAN Filter configuration, please refer to
the section 3.4 of the user manual).
Step9: Set the Device ID of the I-7530A-MR_A and I-7530A-MR_B as 1
and 2 respectively. Here the “Specific CAN ID” field does not be
used (For more information about Modbus RTU configuration,
please refer to the section 5 of the user manual)
Step10: Click the “Setting” button to save these CAN/COM parameters
into the EEPROM of the I-7530A-MR_A.
Step11: Repeat Step 1 ~ Step 9 to configure the I-7530A-MR_B converter
with the same configurations as the I-7530A-MR_A.
4. Testing the I-7530A-MRs
Step1: Turn off the DC power connected with these two I-7530A-MR
modules.
Step2: Set the Init/Normal switches on the back of the I-7530A-MR A and
I-7530A-MR_B to the “Normal” position. Then, turn on the DC
power. The CAN LED and UART LED of the I-7530A-MR_A and B
will be turned off. It means these two I-7530A-MR converters are
working in the operation mode.
Step3: Run the UART2CAN Utility twice. Then duplicate I-7530A-MR
Utility dialogs will be displayed on the PC’s screen. Assume that
one is named as Utility_A and the other is Utility_B.
Step4: Select the proper COM port parameters and configure the RS-232
COM1 and the RS-232 COM2 of the PC. The COM1 and COM2
ports of the PC will be used for connecting with the I-7530A-MR_A
and I-7530A-MR_B respectively. Then change the communication
mode of Utility_A and Utility_B to Modbus RTU mode. The two
Utility dialogs are similar with the following picture.
