3. Notes on Usage

3.1

Turning the Power On/Off

Turn the power of the E2/E2 Lite and the user system following the procedure below.

3.1.1

When a Separate Power Supply is Used for the User System

<When using the emulator>

(1) Check that the power is off.

(2) Connect the user system.

Connect the emulator and the user system with a user-system interface cable.

(3) Connect the host machine and turn on the emulator.

Connect the emulator and the host machine with a USB interface cable. The E2/E2 Lite is turned on by
connecting the USB interface cable.

(4) Launch the emulator debugger or programming software.

Launch the emulator debugger or programming software.

(5) Turn on the user system.

Turn on the user system.

(6) Connect the emulator debugger or programming software to the emulator.

Connections may vary depending on software.

<When finished using the emulator>

(1) Disconnect the emulator from the emulator debugger or programming software.

Disconnections may vary depending on software.

(2) Turn off the user system.

Turn off the user system.

(3) Close the emulator debugger or programming software.

Close the emulator debugger or programming software.

(4) Turn off the emulator and disconnect the emulator.

Disconnect the USB interface cable from the emulator. The E2/E2 Lite is turned off by disconnecting from
the USB interface cable.

(5) Disconnect the user system.

Disconnect the user-system interface cable from the user system.

CAUTION

Notes on the User System Power Supply:

While the power of the user system is on, do not turn off the host machine or unplug the USB
interface cable.

The user system may be damaged due to leakages current.
