1. CAN
CAN was developed to cause this problem by German company Bosch in 1986. It used bus communication method
rather than 1:1 communication method which UART based serial communication has, and various technologies
were incorporated to prevent communication conflicts.
1) Message Directional
ID is assigned to CAN according to the priority of the message and used to communicated. This causes each node
to self-judge the message delivered to each node and ignore the message which is except it needs.
2) Enhanced Error Mechanism
Several mechanisms have applied to CAN to improve communication reliability. If communication state detection,
error check and management were carried out in conventional SW method, CAN can detect and handle errors
occurring during communication due to the error detection mechanism built in HW in real time.
3) Multi-Master
CAN communication is conducted based on priority of each note and message without a network administrator which
manages the network. If arbitrary node A message is assigned with the highest priority ID, the rest of the nodes
communicate according to the priority of each ID after the A message is sent.

4. Features
eCAN performs the following functions, as a converter converting signals coming from the CAN BUS into network
signals over the LAN port, or delivers signals to the CAN BUS via network signals.
1) Converts CAN communication to socket communication
Converts CAN communication which requires a direct connection to the cable facility, to socket communication
which the network communication is able.
2) CAN VBUS Power Supply Feature
In addition to the 5V Power supply through DC adapter, eCAN can be also powered by pin no.9 of the CAN port.
3) VCP(Virtual Com Port) Function
ComRedirector, a virtual COM Port(VCP) among the utilities provided, enables using LAN port of the eCAN
connected to the same network as if it were a serial port mounted on a PC. It also supports Sever/Client mode to
connect serial socket.
4) Web Page Setup Feature
Users can change, save, reboot the eCAN through its own Web Page provided.

5. How to Use
Connection between CAN equipment(CAN Bus) and PC
eCAN performs ComRedirector, TCP Server/Client and UPD connection over the network. Users can check CAN
data on PC over the network, or generate CAN data and forward it to CAN Bus.
Connection between CAN equipment(CAN Bus)
To enable communication between different CAN Buses, set two eCANs to Server and Client(Target: Server) each
and connect to the network.
* Please refer to 6. How to Setup for more information on setting up each connection.

6. How to Setup
First, check if the input voltage supplied to eCAN is consistent with 5V 1A and supply the voltage correctly. If power
is supplied normally, the eCAN starts booting with power on.
There are LEDs such as RDY to check the operation status. Please refer to the manual Ch3. Product – LED menu
in for more information.
To view or setup your eCAN environment, you should use eCANConfig utility, or use the WebPage to connect to the
IP Address, the network address on which the eCAN is operating.
Setting through Web Page
(1) Preparation for Connection(when connecting PC-eCAN without AP)

Precautions for Accessing the Web
The setting using the web is not supported in the network environment below 10Mbps.
PC 10Mbps eCAN
Therefore, if you change the settings using the web, you should connect the integrated device to
the 100Mbps network environment or PC as below. If it is difficult to configure the environment
below, you can use the eCANConfig utility to set up your device.
