3.2.3
The E6000 emulator incorporates a power supply monitor circuit From AC adapter that only lights
the red LED when a voltage higher than 4.75 V is supplied. If this LED does not light, you should
check the E6000 emulator voltage level. An input voltage less than 4.75 V could indicate that
insufficient current is being supplied to the E6000 emulator.
Note: Use the provided AC adapter for the E6000 emulator.
3.3
For the following user system interface signals, control circuits are connected between the user
system and the MCU in the E6000 emulator:
3.3.1
All user system interface signals are over/reverse voltage protected by use of diode arrays and
have pull-up resistors.
The VCC pin is monitored by the E6000 emulator to detect a powered user system hardware
presence.
3.3.2
The interface circuit between the MCU in the E6000 emulator and the user system has a signal
delay of about 3 ns due to the user system interface cable and it includes pull-up resistors.
Therefore, high-impedance signals will be pulled up to the high level. When connecting the E6000
emulator to a user system, adjust the user system hardware to compensate for propagation delays.
