4.1 Turning On the Power
4.1.1 Checking Connections of the Emulator System
Before turning the power ON, check the connection of the interface cable to the host machine,
PC7501, emulation probe, and target system.
4.1.2 Turning ON/OFF the Power
• Turn ON the power of the emulator and target system as simultaneously as possible.
• Turn OFF the power of the emulator and target system as simultaneously as possible.
• Do not leave either the emulator or target system powered on, because of leakage current the
internal circuits may be damaged.
•When turning ON the power again after shutting OFF the power, wait for 10 seconds.
4.1.3 Power Supply to the Target System
• Pins Vcc1 and Vcc2 are connected in order to monitor target system voltage. For this reason, the
emulator cannot supply power to the target system. Therefore, provide the target system with a
separate power supply.
• The voltage of the target system should be as follows.
(1) When JP1 is set as Vcc1 = Vcc2:
2.7 V ≤ Vcc1 = Vcc2 ≤ 5.5 V
(2) When JP1 is set as Vcc1 > Vcc2:
4.8 V ≤ Vcc1 ≤ 5.2 V
2.7 V ≤ Vcc2 < Vcc1
•Do not change the voltage of the target system after turning on the power.
