2.2.5 Precautions on Connecting the User System
When connecting the evaluation chip board to the user system, note the following:
1. Secure the E6000H station location.
Place the E6000H station and evaluation chip board so that the trace cable is not bent or twisted, as shown
below. A bent or twisted cable will impose stress on the user interface, leading to connection or contact
failure. Make sure that the E6000H station is placed in a secure position so that it does not move and impose
stress on the user interface while being used.

2. Make sure the power supply is off.
Before connecting the evaluation chip board to the user system, check that the emulator and the user system
are turned off.
3. Connect Vcc to the user system power.
The emulator monitors and determines whether the user system is turned on or off by the following Vcc pins:
(a) Connecting the dedicated connector for HS1650EPH60H: Pin UCN2-121
(b) Connecting the user system interface board: Vcc: All Vcc pins
Accordingly, after connecting the user system to the emulator, be sure to supply power to the Vcc pins.
Otherwise, the emulator assumes that the user system is not connected.
When the user system is connected, check that the power of the user system is supplied to these pins.
