RTMC200-232 is a RS-232 interface based function-ready controller that accepts either serial ASCII string commands or Modbus protocol commands to perform real-time tasks in the applications of monitoring, measuring, and controls. It is based on a high-performance 16-bit and 40 MIPS DSP core processor with enhanced peripheral interface. The advanced embedded 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 simple ASCII strings or Modbus protocol  commands through RS232 serial port to read A/D, to output D/A and PWM, to set I/O or read I/O, or to read event counters. You can choose to have the returning data in either ASCII format or binary format based on setup configuration. You can configure the two D/A outputs as the normal digital to analog outputs or as function generators. When configured as function generators,  one D/A will output sine waveform with frequency and amplitude adjustable, and the other one can be a ramp function for trapezoidal profile generation. 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.

The ASCII string commands are intuitive and simple. For example, the command @1RAF5 will read the A/D channel 5 with digital filtering ( cut-off frequency is set by another command) from device address 1.  @1RAU3 will read the A/D channel 3 with raw data from device address 1.

We offer three different board assembly configurations to give you a flexibility to choose the one that fits your hardware interface. The RTMC200-232A has no 0.1" pin header connectors installed; the RTMC200-232B is fully populated with 0.1" headers and terminal blocks as shown in the above picture; the RTMC200-232C is specially to be used as a daughter board with all 0.1" pin header connectors installed for daughter board interface. All of the three different boards function the same as stated in RTMC200 series controller's User Manual
