In this chapter, we will introduce the basic usage of CANWiFi-200T and the related
hardware and software installation settings. You can quickly grasp the usage of it and
have an intuitive understanding of the network and CAN device communication through
our introduction.
Before using the CANWiFi-200T device, we need to know the network parameters such
as device IP address. CANWiFi-200T device supports two ways to obtain the IP
address, including “Static Acquisition” and “Dynamic Acquisition”. “Static Acquisition”
means that the device uses “IP Address”, “Subnet Mask” and “Gateway” specified by
users; “Dynamic Acquisition”means that the device uses DHCP protocol to obtain the
information such as IP address, subnet mask and gateway from the DHCP server on
the network.
3.1 Device IP Factory Setting
The default IP address of CANWiFi-200T device is 192.168.0.178.
3.2 Connect and obtain Device IP
When users forget the device IP address or the device uses DHCP protocol to obtain
the IP address automatically, the current device IP can be obtained through ZNetCom
software.
ZNetCom software is the configuration software of CANWiFi-200T device running on
the Windows platform. No matter what the current CANWiFi-200T device IP is, you can
obtain the current device IP through ZNetCom software and configure the IP. Use
ZnetCom software to obtain the CANWiFi-200T device IP as follows:
1. Connect the hardware to power up the device with 9~24V DC power supply, and
use a crossover cable to connect the LAN port of the device to the PC network port.
In addition, when the WLAN of CANWiFi-200T operates in the AP mode and the LAN
port is not connected, users can search and find the “CANWiFi-200T”device via the
network interface card of PC, as shown in Figure 3-1. The PC wireless network
interface card is set to automatically obtain IP, and input the password of "12345678"
when connection.

3.3 PC and Device Network Segment Detection
Before using PC to communicate with the CANWiFi-200T device, users should ensure
that there is an Ethernet card in the user's PC. Moreover, PC and the CANWiFi-200T
device must be in the same network segment.
A default IP address (192.168.0.178) and network mask (255.255.255.0) are set for a
CANET device in the factory. Users can check whether the device and the PC are in the
same network segment according to the process shown in Figure 3-4. If they are in the
same network segment, you do not need to read the following PC network setting
information. If not, then the information of this network setting is very important for you.
Figure 3-4: Check whether the CANWiFi-200T device IP and PC are in the same
network segment
The following information explains how to make the PC and CANWiFi-200T device in
the same network segment.
If users use the operating system of Windows2000/XP/7, then there are two ways to do
it, one is to add local IP address and the other is to modify local IP address.

1.Add local IP address
Assuming that the IP address of the PC is 192.168.2.3, and the default IP address of
CANWiFi-200T device is 192.168.0.178.
After login the operating system, users right-click Network Neighborhood to select
Properties. At this time, the network connection window is opened, then select Local
Area Connection icon (Note, this connection is to connect the CANWiFi-200T device
network. If users use multiple network interface cards, there may be several local
connections, please pay attention to select), then right-click Local Area Connection to
select Properties. The pop-up window is shown in Figure 3-5.

Figure 3-9: TCP/IP properties
Now, the CANWiFi-200T device can communicate with the PC.
3.4 Communication between CANWiFi-200T and USBCAN
Interface Card
We need a device with CAN port to help demonstrate how the CANWiFi-200T device
implements bidirectional transparent conversion of CAN network data and Ethernet
data. Here we use the USBCAN-II interface card, which is very convenient to use, and
its related information can be found on the website http://www.zlg.cn/.
First, connect the CANWiFi-200T device to a PC with the cable, and connect the
CANWiFi-200T CAN0 port to the USBCAN-II CAN0 port with the twisted pair (the CANH
terminals are connected; the CANL terminals are connected; pay attention to configure
a 120 ohm terminal resistance). And then use the USB cable to connect the USBCAN-II
interface card to the PC, and finally power up the USBCAN-II interface card and
CANWiFi-200T device. Then run the CANtest software on the PC (as shown in Figure
3-10). The CANtest test software can be found in the product CD (need to install).
