Product Description

Introduction of UID820 UIM Simple CAN protocol Digital I/O Controller

UID828 is a CAN bus series digital port input and output controller, using UIROBOT SimpleCAN communication protocol. It has 8 directions and can input and output port command configuration. The 8 ports can be configured as a digital or analog input and output. The two digital I/O port can be configured as a PWM (pulse width modulation) output. PWM wave frequency and duty cycle can be adjusted through the instruction. UID828 and UIM242 series of stepping motor control driver consists of a mixture of local area network control, can also be composed of data acquisition and output control network.

The users familiar with the CAN protocol and CAN main control machine with the user, can use SimpleCAN protocol UIROBOT provide with directly to to realize the control of the motor - sensor - electromagnetic valve network .

The user not want to understand the CAN protocol or not have CAN host control can use uirobot UIM2501 CAN/RS232 converter, to control the motor - sensor - electromagnetic valve network through RS232 simple and intuitive web-based instruction, replacing the user directly using the relatively complex CAN protocol. A user's PC only need a UIM2501, can simultaneously control up to 100 sets of UID828 data acquisition system with UIM242 drive.

Control structure of UID828 is simple, high fault tolerance. The Enclosure of data acquisition is made of die-cast aluminum to provide a rugged durable protection and improves the heat dissipation.

UID828 with a 8 bit multi-function switch. Dial 1 to dial 7 at power-up, provide the address identification code UID828. Dial 8 in ON (see instructions), CAN bus terminal resistor built-in UID828 is enabled. The factory, UID828 address identification code is set to 7, at the same time not enable terminal resistance.

DB9 I/O Port

It is a standard male DB9 connector. The first pin is for GND. Pin 2 to Pin 9 are for 8 I/O ports. (Pin 2 for I/O port 1, Pin 3 for I/O port 2, etc.)

DIP SWITCH

UID820 controller has an 8-bit DIP switch. When powering up, DIP1 – DIP7 are read as the UID820 controller’s ID/address. DIP8 can be used to enable the built-in terminating resistor when it is set at “ON” side (as shown in figure 0-2). Factory default of the DIP switch is: UID820 controller ID = 7 and terminating resistor disabled.
WARNING: The terminating resistor must be DISABLED unless the UID820 controller is at the end of the CAN Network.
UID820 controller ID can be set through the DIP switch through the binary method:

ID/Address = D1*2 0 + D2*2 1 + D3*2 2 + D4*2 3 + D5*2 4 + D6*2 5 + D7*2 6

When actuator Dx ( x = 1, 2, …7) is set at “ON” side, Dx = 1；otherwise, Dx = 0. For example, if we want to set the UID820 controller ID to 63,

63 = 1*2 0 +1*2 1 +1*2 2 +1*2 3 +1*2 4 +1*2 5 +0*2 6

That is, D1, D2, D3, D4, D5, D6 are all set at “ON” side while D7 is set at the other side,as shown in figure 0-2.

DIP Switch Setting

Typical Application

Control Area Network (CAN) provides a simple and reliable network solution. When a UIM2501 CAN/RS232 converter is used in the network, the following wiring scheme can be applied (figure 0-3).

Please note: in multiple-node CAN application (network consists of multiple UID820 controllers and/or UIM242 controllers), all nodes should be connected onto a twist wire pair, as displayed in figure 0-3. Star connection scheme must be avoided. Meanwhile, the stub must not exceed 2cm each (the shorter, the better). Both ends of the bus should be terminated with120Ω terminating resistors. Shielded 120 ohm CAN bus cable is recommended.

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.
