Electronic controller RCB500 data sheet

US-BOARDS High Performance Controller Board RB500 is a data acquisition and processing board able to process analog and digital inputs and to control several digital outputs.

RB500 feature an easy to use BASIC like programming language and a powerful programming and testing environment running on almost any Microsoft Windows Operating System. Equipped with a high performance 32 bit microprocessor the RB500 can operate as a stand-alone programmable device, requiring no connection to a PC.

Connectivity

All the RB500 I/O connections are done using the two DB 25 and DB 9 connectors on the front of the board. Connectivity to a PC is provided by a RS232 or USB line. Data lines can be DIN : 5 Volt Digital Inputs ANA1: 0 – 5 Volt analog inputs Pulse (RC radio) lines DOUT: 24 Volt 1 A max Digital Outputs

Typical applications

The DAB-500 can be used in a wide range of applications, where sensing of several inputs, complex data processing capabilities, ease of configuration are required. It is specially suited for

- Industrial Automation
- Alarm systems
- Robotics
- Automatic Guided Vehicles
- Flight simulators
- Remote presence Systems

Power Connection

The board is powered by a 5 V external power supply. Connection is made via the provided flat ribbon connector, connected to pin 19 (GROUND) and 20 (5 Volts) of connector J8. A stabilized power supply (5V, 200 mA) must be used.

Data Connection

Connection to RC Radio, Joystick and other low current sensors and actuators is done via the 25 and 9 pin connectors located in front of the connector. The functions of many pins vary depending on user configuration. Pin assignment is found in the tables below (Table 1 and Table 2).

Default I/O Configuration

While the controller can be configured so that practically any Digital, Analog and RC pin can be used for any purpose, the controller’s factory default configuration provides an assignment that is suitable for most applications.

The figure below shows how to wire the controller to two analog potentiometers, an RC radio, and the RS232 port. It also shows how to connect two outputs to motor brake solenoids and another output to an external status LED. You may omit any connection that is not required in your application. The controller automatically arbitrates the command priorities depending on the presence of a valid command signal in the following order: 1-RS232, 2-RC Pulse, 3-Analog.
If needed, use the Roborun+ PC Utility to change the pin assignments and the command priority

Status LED Flashing Patterns

After the controller is powered on, the Power LED will turn on, indicating that the controller is On. The Status LED will be flashing at a 2 seconds interval. The flashing pattern provides operating or exception status information.

4 Normal operations flashing pattern

Additional status information may be obtained by monitoring the controller with the PC utility.
