I-7540D-WF CAN to Wi-Fi Converter User’s Manual (Ver. 2.0, Jan/2012) ------------- 37
4.1 Hardware Installation
Before use, associated hardware configuration, the steps described as
follows
：
Step 1: Checking the I-7540D-WF firmware operation mode
In the operation mode, the user can complete the wireless CAN data
transmission via the I-7540D-WF.
It needs to set the DIP switch to the
Normal position (operating mode) as Figure 2-14; as resetting the power,
I-7540D-WF will be in the operation mode.
Step 2: Enabling 120
Ω
termination resistors (if I-7540D-WF is a
terminal in the CAN network)
Please open the I-7540D-WF cover and use the JP2 to activate the
120
Ω
terminal resistor built in the module, as the Figure 2-7, After finishing
set the JP2, 120 ohm termination resistors can be enabled.
Step 3: CAN bus network connection
Refer to Figure 2-4 for wiring structure, and connect the I-7540D-WF's
CAN interface with other devices.
Step 4: Serial port connection
I-7540D-WF supports RS-232 serial communication. The circuit
configuration is as shown in Figure 2-5.
Step 5: Power connection
Connect the power supply to I-7540D-WF's power terminator, as
shown in Figure 4-3.
