• When a PC is connected, the transistor (Q102) in the Main CPU (IC3) [when PX1 is used] or the extension CPU (IC3) [when

PX10 is used]. The connection is detected by interruption through IRQ of the Main CPU or the extension CPU. When the con-
nection with the PC is disconnected (the cable is unplugged), it is also determined as an interruption.

• When the USB communications are enabled such as by initialize on the equipment side, the Main CPU or the extension CPU

sets USB_F_ENB# ON (Active: "L"). By this, the respective inputs to OR (IC102) become "L", and the transistor (Q101) goes ON
(Active: H).  Then, the D+ signal of USB is pulled up.

• The PC determines that the D+ line of USB has become "H" and thus verifies the connection.
• After the connection is recognized, a negotiation is made, and then the communications are made normally.

• This equipment uses the video control circuit inside the Main CPU (IC3) since the equipment does not have a logic exclusively

for head control.

The control signal output is produced through the video control circuit in accordance with the interface specifications of the sublima-
tion head. With the output signal, there are some parts that do not conform to some of the timings of the sublimation head, so the
timings are controlled by adding an external logic.

The 64MHz system clock divided by the inside Timer is used for the 16MHz head clock, and it is output to the external as a 16MHz 
clock and is input to VCLKIN of VDC.
