It is based on a high-performance 16-bit 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 perform four PI controller feedback controls, to read A/D, to output D/A and PWM, to set I/O or read I/O, and to read event counters. 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 RTMC600 Series Controllers (PDF).

The ASCII string commands are intuitive and simple. For example, the command @1XR2 5000 will set the control reference2 for PI controller2 to 5000 for this controller at device address 1.  @2RAU3 will read the A/D channel 3 with raw data from a slave controller, such as RTMC600-CAN, 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 RTMC600-USB-CAN-A has no 0.1" pin header connectors installed at all; the RTMC600-USB-CAN-B is fully populated with 0.1 " headers and terminal blocks as shown in the above picture; the RTMC600-USB-CAN-C is specially to be used as a daughter board with all 0.1" pin header connectors for daughter board interface. All of the three different boards function the same as stated in RTMC600 series controller's User Manual
