I-2533 Quick Start
1. Introduction
This quick start helps users to apply the I-2533 in users’ applications
quickly. If users need the details of I-2533, please refer to the I-2533 user
manual. Users can free download it from the web site as follows or get it
from product CD (path: CAN/Converter/I-2533).

2. Hardware Installation
Before using I-2533, some things must be done.
1. Prepare one pair of I-2533.
2. Set the CAN baud rate of each I-2533 by using rotary switch. You
can refer to the following table for details. (If you set the rotary
switch to “A”, please use utility tool to do the configuration before.)

3. Utility Tool
When users want to use user-defined baud rate or set the message
filter, I-2533 utility tool may be needed. It can be free downloaded from the
following web site or get it in the product CD (path: CAN/Converter/I-2533
/Software):
http://www.icpdas.com/products/Remote_IO/can_bus/i-2533.htm
After getting the utility tool, please follow the following steps to set the
baud rate and message filter.

Step0: Power off the I-2533. Set the rotary switch to “F”, and connect the
PC available COM port with the COM port of the I-2533. Users can
find the communication cable in the product box. When connecting
to the COM port of I-2533, the TxD pin of the cable is connected to
the TXD pin of the COM port, RXD pin of the cable is connected to
the RXD pin of the COM port, and GND pin of the cable is
connected to the GND pin of the COM port. Then, power on the I2533.

Step1: Execute the I2533_Utility.exe, the dialog of the I-2533 Utility will be
poped up. Select the PC COM port which is connected with the
COM port of the I-2533. Then, click “Connect” button.

Step2: Users can set the baud rate on the “User-defined Baud Rate” field.
Here, fill “250000” for 250 kbps. Then, set the filter by using the
“from” field, “to” field, and “Add” button. For example, If users want
to pass the CAN message with ID 0x4 and 0x5 in the CAN 2.0A
specification. Fill the value “4” in the “from” field of CAN 2.0A, and
the value “5” in the “to” field of CAN 2.0A.
Step3: Click “Add” button to add this configuration. The configuration is
shown on the “Pass List” field. If the “Pass List” is not empty, only
the messages matched with the “Pass List” will be passed. If the
“Pass List” filed is empty, it means all-pass. If users want to pass
the message with ID 0x0 in the CAN 2.0A specification, fill the
value “0” in both of “from” and “to” field and click “Add” button.

Step4:.The method of configuring the message filter of the CAN 2.0B
messages is similar with the configuration steps of the message
filter of the CAN 2.0A messages. After finishing all of the
configurations, click “Save all configuration” to store the
configuration in the I-2533.
Step5: When the procedure is successful, the following message will be
shown.
Step6. After finishing the configuration, set the rotary switch value to “0” ~
“A” and reboot the I-2533. The CAN message filter will be applied
automatically in the value “0” ~ “A” of the rotary switch. The CAN
baud rate set by utility is only appled when the rotary switch is set
to “A”.
