It is based on a high-performance 16-bit 40 MIPS DSP core processor with enhanced peripheral interface. The advanced firmware has been developed and embedded into this controller so that the customer neither needs to develop real-time embedded firmware nor needs development tools. To command this device, the user simply sends ASCII strings or Modbus protocol through USB 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 returning 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 @1XS 2000 will set the speed reference to 2000 rpm for this controller at device address 1.  @2RAU3 will read the A/D channel 3 with raw data from a slave controller, such as RTMC400-CAN, at device address 2.

This board serves as a master and  through its daisy-chainable connectors, such as RJ-45 Jacks or J4 header connector, up to 63 boards of RTMC400-CAN can be connected to form a distributed networking system

We offer three different board configurations to give you a flexibility to choose the one that fits your hardware interface. The RTMC400-USB-CAN-A has no 0.1" pin header connectors installed at all; the RTMC400-USB-CAN-B is fully populated with 0.1 " headers and terminal blocks as shown in the above picture; the RTMC400-USB-CAN-C 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
