Quick Start User Guide
1. Introduction
The CAN (Controller Area Network) is a serial communication protocol, which
efficiently supports distributed real-time control with a very high level of security.
It is an especially suited for networking “intelligent” devices as well as sensors
and actuators within a system or sub-system. In CAN networks, there is no
addressing of subscribers or stations in the conventional sense, but instead,
prioritized messages are transmitted. CANopen is one kind of the network
protocols based on the CAN bus and mainly used for machine control network,
such as textile machinery, printing machines, injection molding machinery, or
packaging machines, etc. CANopen is a low level network that provides
connections between simple industrial devices (sensors, actuators) and
higher-level devices (controllers), as shown in Figure 1.1.

2. Hardware Installation
Step1: Connect the (R) Vs+ and (B) GND pins of the GW-7433D module to
the DC power supply (10~30VDC).
Step3: Connect the Ethernet ports of the GW-7433D and the PC to the hub
with standard network cable respectively.
Step4: Connect the CAN ports of theGW-7433D with CANopen slave devices
3. Configure the GW-7433D
Before starting the GW-7433D gateway, users need to configure the
parameters of it via the “Configuration Wizard” and “GW-7433D Utility” tools.
The details of this procedure are shown below. For more information about
setting steps, please refer to section 5 of the GW-7433D’s user’s manual.
Step1: Configure the network parameters via “Configuration Wizard”
To Use the Configuration Wizard, you must first install PCDiag.

Step2: After configuring the network setting of the GW-7433D, users can use
the GW-7433D Utility tool to configure it.
Step3: Click the “Connect” button to connect with the GW-7433D. These steps
are shown in the following figure.
