Hardware Installation
Before using I-7540D / I-7540DM series devices, some
things must be done.
Step 1: Prepare one I-7540D / I-7540DM series device
Step 2: Determine if the CAN Bus terminal resistor is
needed or not
Check the application structure, and determine if the
terminal resistor is needed to be enabled or not. Before
you continue, if you have changed the settings from
default then it is necessary to open the cover of I-7540D
and re-configure JP3 jumpers to enable it again, as shown
in below figure. However if the I-7540D’s still have their
default settings then it is not necessary to open and reset
them because the default configuration is enabled.

Step 3: Connect the CAN port, ethernet and power line of
the module
Connect the (R)Vs+ and (B)GND pins of the I-7540D
module to the DC power supply (10~30VDC). And
connect the Ethernet ports of the I-7540D and the PC
with standard network cable respectively.
The pin assignment of the module are as follows.

When users want to change the CAN/COM and Ethernet
parameters of I-7540D, Utility tool may be needed.
Step 1: Install the I-7540D Utility tool
The software is located at:

Step 2: Setting up I-7540D module
The default network setting of the I-7540D is shown below.
IP: 192.168.255.1
Mask: 255.255.0.0
Gateway: 192.168.0.1
Before communicate with the I-7540D, you must change the PC’s
local area network same as the I-7540D. Then power on the
module and execute the I-7532-FD Utility tool.
