User Manual

RTMC400-485 controller is made for motion control applications, which offers speed PID controller, position PID controller, Quadrature encoder input, stepper motor indexers, and plus many similar  features offered in RTM200 series controller.

RTMC400-485 is a RS-485 interface based function-ready slave controller that accepts either serial ASCII string commands or Modbus protocol to perform real-time tasks in the applications of monitoring, measuring, and controls. All commands are sent through RS-485 standard communication port.  It is based on a high-performance 16-bit 40 MIPS DSP core processor with enhanced peripheral interface. The advanced embedded firmware has been developed and embedded into this controller so that customer neither needs to develop real-time embedded software nor needs development tools. To command this device, the user simply sends ASCII strings or Modbus protocol  through RS-485 serial port to do speed control, position control, speed measuring, position measuring, stepper motor control, read A/D, output D/A and PWM, set I/O or read I/O, etc. You can choose to have the return data in either ASCII format or binary format based on setup configuration. Each A/D input can be filtered or passed through as raw data. This controller is capable of automatically recognizing ASCII protocol and Modbus protocol. For more details, click here to download user manual for RTMC400 Series Controllers (PDF).

The ASCII string commands are intuitive and simple. For example, the command @2XS 2000 will set the speed reference to 2000 rpm for this controller at device address 2.  @2RAU3 will read the A/D channel 3 with raw data from this controller at device address 2.

We offer three different board configurations to give you a flexibility to choose the one that fits your hardware interface. The RTMC400-485A has no 0.1" pin header connectors installed; the RTMC400-485B is fully populated with 0.1" headers and terminal blocks as shown in the above picture; the RTMC400-485C is specially designed to be used as a daughter board with all 0.1" pin header connectors for daughter board pin fit. All of the three different boards function the same as stated in RTMC400 series controller's User Manual
