4.7 CAN Bus Connection
The physical layer mainly transmits inter-device signals, converts various information
into transmittable physical signals (usually electrical or optical signals), and transmits
these signals to other target devices. For this purpose, CAN-bus has made detailed
regulations on signal levels, cables and connectors used for communication.
Two standards are released after CAN-bus was standardized by ISO, namely
ISO11898-2 (125kbps-1Mbps high-speed communication standard) and ISO11898-3
(low-speed communication standard less than 125 kbps).
The CAN transceiver determines the bus level based on the voltage difference
between the two cables. This transmission method is called differential transmission.
There are only two possibilities for the level signal transmitted on the cable, namely the
dominant level and the recessive level. The dominant level indicates logic 0, and the
recessive level indicates logic 1. Table 4.5 lists the high-speed CAN electrical
characteristics.

Figure 4.2 Typical high-speed CAN network connection
The CAN bus adopts balanced transmission. ISO11898-2 stipulates: In the
high-speed CAN, a 120 ohm terminal resistor needs to be connected to the network
terminal node to eliminate signal reflection on the bus and avoid signal distortion. Figure
4.2 shows the high-speed CAN network topology.
The device has a built-in 120 ohm terminal resistance, which can be configured to
turn on or off by using the CANFDWIFI-100U configuration tool.
Note: The bus communication distance and communication rate are related to the field application
and can be designed according to the actual application and related standards. The CAN-Bus cable can
use ordinary twisted pair, shielded twisted pair or standard bus communication cable. In long-distance
communication, the terminal resistance value needs to be selected according to the communication
distance, cable impedance and number of nodes.

5. Quick Instructions
This chapter describes the basic usage of CANFDWIFI-100U and the installation
settings of related software and hardware. You will quickly grasp how to use the product,
and have an intuitive understanding of the communication between the network and CAN
devices.
Before using the CANFDWIFI-100U device, learn about the network parameters such
as the IP address of the device. The CANFDWIFI-100U device supports two IPacquisition
methods: "static acquisition" and "dynamic acquisition". "Static acquisition" indicates that
the device uses the "IP address", "subnet mask" and "gateway" specified by the user;
"Dynamic acquisition" indicates that the device obtains the IP address, subnet mask, and
gateway information from the DHCP server on the network over DHCP.
5.1 Hardware Connection
Connect the device to a 9-48 V DC power supply, and use a crossover cable to
connect the LAN port of the device to the network port of the PC. Or, when the wireless
WLAN of CANWIFI-100U is running in AP mode and the LAN port is not connected, the
device "CANFDWIFI100U" can be searched through the wireless network card of the PC,
as shown in Figure 5.1. The wireless network card of the PC is set to obtain the IP
address automatically, and you can connect by entering the wireless password of
"12345678".

5.2 Software Installation
Before using the device, install the supporting software ZCANPRO. The software can
be downloaded from the official website of ZLG Electronics http://www.zlg.cn.
5.3 Configuring the Device
When the device IP address is forgotten or the device uses DHCP to obtain the IP
address automatically, the current IP address of the device can be obtained by using the
network device configuration tool software.
Before using the device, configure the device IP address, CAN port baud rate and
other parameters. Configure the device by using the network device configuration tool in
ZCANPRO. The procedure is as follows:
5.3.1 Running the Configuration Tool
Run the ZCANPRO software, click [Tools] in the upper part of the software, and select
[Network Device Configuration Tool], as shown in the red circle in Figure 5.2. Figure 5.3
shows the configuration software interface.

NIC configuration
Before using the PC to communicate with the CANFDWIFI-100U device, ensure that
there is an Ethernet card in the PC, and the PC and the CANFDWIFI-100U device must
be in the same network segment.
Before using the PC to communicate with the device, ensure that an Ethernet card is
installed on the user's PC, and the PC and the device must be in the same network
segment. The device is set with a default IP address (192.168.0.178) and network mask
(255.255.255.0) when it leaves the factory. Check whether the device is in the same
network segment as the user's PC according to the process shown in Figure 5.6 Same
Network Segment Detection Flowchart.

Figure 5.6 Detection process on the same network segment
There are two ways to keep the user's PC and device in the same network segment.
The first method is to change the IP address of the PC. Open [Control Panel] on the
PC, double-click the [Network Connection] icon, click to select the [LocalArea Connection]
corresponding to the network card of the connected device, right-click and choose
[Properties]. Double-click on the pop-up page to select [Internet Protocol Version 4
(TCP/IPv4)]. The page as shown in Figure 5.7 appears. Select [Use the following IP
address], and enter the IP address 192.168.0.55, the subnet mask 255.255.255.0, and the
default gateway 192.168.0.1 (the DNS part can be left blank). Click [OK] on this page and
on the "LocalArea Connection Properties" page, and wait until the system configuration is
complete.

Figure 5.7 TCP/IP properties
The second method is to change the IP address of the device. On the interface
shown in Figure 5.4, change [IP] in [General Ethernet] to the IP address of the same
network segment as the PC. For example, if the IP address of the PC is 192.168.7.115,
the subnet mask is 255.255.255.0, and the default gateway is 192.168.0.1, change [IP] of
[NIC Configuration] to 192.168.7.178, and change the device gateway IP to "192.168.7.1".
CAN(FD) configuration
For CAN(FD) normal communication, set the CAN(FD) baud rate to be consistent
with that on the CAN-Bus network. The device is configured as an ISO CANFD controller
by default. The baud rate of the arbitration domain is 1 Mbps, and the baud rate of the
data domain is 5 Mbps. To modify the data, adjust the arbitration domain baud rate and
data domain baud rate in the CAN configuration on the interface.
Working mode configuration
The default working mode of the device is TCP Server mode, the port is 8000, and
the network card is universal Ethernet. Click the attribute value of [Network Forwarding]
on the interface. On the pop-up interface, view or modify the working mode, as shown in
Figure 5.8.
