1. CONTROL I
1-1. NAME
CONTROL I
1-2. SCOPE OF APPLICATION
The CONTROL I terminal has been adopted from system stereos DHC-MD555, DHC-MD777, and JMD-7. Connecting by the PC
connection kit PCLK-PX1 and bi-directional remote commander RM-IA10K (J model only) to the CONTROL I terminal facilitates basic
operations of the system stereo, music editing from CD to MD, and title inputs to MDs.
The terminals connecting the optional cassette decks TC-PX100 and TC-SD1 of the above system stereo have different connector shapes,
but adopt the same communication format as CONTROL I.
1-3. COMPATIBILITY
CONTROL I has no compatibility with the conventionally used AU BUS in terms of both connector shape and communication format.
CONTROL I also has no compatibility with the CONTROL-A1 adopted for the component stereo in terms of connector shape and
communication format.
Although CONTROL I has a similar name with i-LINK using the IEEE1394 terminal which thus may cause them to be confused for one
another, these two have no compatibility.
1-4. BASIC CONCEPT
Communication is carried out by the I2C bus between the microprocessors inside the system stereo. In CONTROL I, a special terminal is
equipped to enable communication by this I2C bus with the microprocessor of an external equipment, and at the same time, a terminal for
turning ON the power of the system stereo from an external equipment has also been added.

1-5. SHAPE OF TERMINAL
The CONTROL I terminal uses a MINI DIN 6-pin connector.
This connector is used for DOS/V PC keyboards and PS/2 mouse, but it has no compatibility with the communication format.
However, taking into account connection to this connector by mistake, power and GND pin positions are made the same to prevent
incorrect operations.
