Abstract

PROBLEM TO BE SOLVED: To turn on/off the power source of a computer device by means of control from an in-circuit emulator device by providing an AC outlet terminal which controls a relay circuit provided inside an in-circuit emulator device mainbody so as to turn on/off the power source by means of the signal of a control instruction and outputs an AC power source. SOLUTION: When the power source is inputted to the power source input terminal 53 of a power source control part 50 and a main power source switch 51 is turned-on, an in-circuit emulator device 40 receives power source supply from a power source circuit 52 and starts an operation. Then, the control signal of the power source ON/OFF is outputted to a detecting circuit 24 by the control signal from a terminal equipment which is connected to the in-circuit emulator device 40. The detecting circuit 24 which receives the signal transmits it to an amplifier circuit 56. When the amplifier circuit 56 transmits the signal to the relay circuit 57, a relay switch closes the circuit and the power source is inputted to the computer device, etc., connected to a control output terminal 55.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A detailed description of the present invention will be given below with reference to the drawings of the embodiments. FIG. 1 is a block diagram showing one embodiment of the present invention. With the configuration described above, power is supplied to the AC input terminal 50 of the in-circuit emulator device from the AC line. Further, the AC outlet control output terminal 55 is connected to a power cord of a computer device or another peripheral device. Now, when power is input to the AC power input terminal 53 of the in-circuit emulator device 50 and the main power switch 51 is turned on, the in-circuit emulator device 40 is supplied with power from the power circuit 52 and starts operating.

Next, the in-circuit emulator device 4
A control signal from a terminal device (not shown) connected to 0 outputs a power ON / OFF control signal to the detection circuit. Upon receiving the signal, the detection circuit 24 transmits the signal to the amplification circuit 56.
