Product Description

Introduction of UIM2502 CAN2.0 / RS232 Optoelectronic Isolation Control Protocol Converter

The UIM2502 RS232-CAN Converting Controller is used in conjunction with UIM242XX stepper motor controller to provide a RS232 interface on the user side and a CAN bus interface on the motor side (factory side). UIM2502 is optoelectronic isolation. With the UIM2502, user will be benefited from the advantages of the CAN network and the simplicity of RS232 protocol, and no need to deal with the complicated CAN protocol, no worry about the communication distance and noise immunity. One UIM2502 controller can network with up to 100 UIM242XX controllers. Interfacing the UIM2502 is simple, intuitive and fault tolerating. Users are not required to have stepper motor driving or CAN protocol knowledge.

UIM2502 is compact in size. The enclosure is made of die-cast aluminum to provide a rugged durable protection and improves the heat dissipation.

Typical Application

UIM2502 converter can work with UIM242XX in fowllwing ways: single slave operation and network operation. Single slave operation means one UIM2502 working with one UIM242 or UID820/828, while network operation means one UIM2502 working with a set of UIM242 and UID820/828 in a CAN network. Typical applications are described below.

Single Slave Operation:

If only one UIM242 or UID820 is used, following wiring scheme (figure 0-3) can be applied.

Please note that, this wiring scheme is mandatory when assigning a controller ID to a UIM242 controller (motor is not required).

Please note: Both ends of the CAN bus should be terminated with120Ω terminating resistors. When UIM2501 is at the end of the CAN bus, a 120Ω terminating resistors shoule be connected between terminals “CANH” and “CANL”.

Wiring Scheme for Standalone Operation

Network Operation:

CAN bus provide a reliable and simple network construction scheme.

The following picture provides a typical network wiring solution. The corresponding relation of UIM2502 and UIM242XX is shown in the above picture.

Please be aware that:
--- A single pair of wires should connect each element of the CAN bus.
--- A star configuration should never be used.
--- Stub length should be shorter than 2cm, and keep these stubs as small as possible.
--- The two ends of the bus should be terminated with 120Ω resistors. When the distance is longer than 100m, specialized 120 ohm impedance shielding twisted-pair cable for CAN bus, should be considered.
--- When UIM2501 is at the end of the CAN bus, a 120Ω terminating resistors shoule be connected between terminals “CANH” and “CANL”.

There is another wiring scheme of network in below picture. When wiring in this way, the length of stub does needs not to be shorter than 2CM, it is more flexible:

Our Company

Shanghai United Intelligence Robotics INC.(Shanghai Uirobot Technology Co., Ltd.) is a high-tech enterprise Registered in the Pudong Zhangjiang High-Tech Park, Uirobot is committed to the development of the robotic industry. Our robotic products have full independent intellectual property rights.

We advocate the philosophy of modular design and manufacture; that is, all our robots are independent modules, with each module using a unified communication protocol to communicate with other modules. In addition, the mechanical interfaces of all modules are also simple and similar to each other.

Different modules can be assembled flexibly to form robots with different functions. With user friendly features, users do not need to understand how the specific module works at the back end; they just need to combine / separate modules according to their request, which can greatly improve the versatility and flexibility of robot application and assembly.

Our lead researchers have many years of research and development experience for industrial and civilian robots.

Under Uirobot, we have developed a variety of robot components, such as wheeled and tracked mobile platforms with dedicated camera rotating heads, military-level operation control boxes, small sizes, powerful functions, intelligent stepper motor controllers, CanBus protocol-based control systems and so on. These components can be used to resolve related technical problems by themselves, or can be combined together to form robotic products with different functions.

Furthermore, we have also launched a series of stepping motor controllers. Suitable for use in both our robots and other applications, these products are characterized by small sizes and strong driving ability. With full intellectual property rights, these items are completely different from similar products on the market. With a size of just 42 x 42 x 14mm (L x W x H), these controllers have flanges that enable direct mounting onto 42, 57, 85 and 110 series stepper motors. Divided into parallel port series, UART (eg. RS232) series, CAN series etc., our ultra-miniature and micro intelligent stepper motor drivers are the only product featuring such small designs, high intelligence and high driving performance in the domestic industry.

We hope to develop new ideas and new realms in the field of robotic research and manufacturing, making our robot products as ubiquitous as home computers, and similarly playing an active role in the daily life of ordinary people. We desire to become the benchmark for robotics companies worldwide, and push the robotics industry into an advanced era.

Believing in "customers first, be creative and proactive", we will continue to provide our clients with great products and top quality services.
