The MMDS11 hardware comprises four separately purchased hardware components:

• Station module - This metal case allows easy access for installing or replacing emulation modules. The station module includes these items:
  • RS-232C serial cable (9-lead)
  • RS-232C adapter (9->25-pin)
  • two cables and 16 logic clips for selecting individual signals
  • built-in power supply (85 to 264 VAC)
  • The station module works across many devices of the M68HC11 family, and once purchased can be reused for any number of M68HC11 development projects.
• Emulation module - Printed circuit board that plugs into the control board and fits inside the station module. The device-specific EM completes functionality for one or more M68HC11 MCUs.
• Target head - Adapter that plugs into the target system's MCU socket. Where necessary, it includes a TQ socket that aligns target-head guidepins with the target.
• Flex cable - Matched impedance ribbon cable that connects the EM to the target head.
