AMP ID is checked only once at the time reset is released or

when the microcomputer is released from the low consump-

tion mode.

When setting AMP ID to 8 or 9, remote control is impossible.

ADJUSTMENT

●Current detection circuit

Amplify and rectify potential differences at

two points in the primary-side current circuit

and send it to the AD-port of the MPU and

obtain data for displaying current value.

●Constant current output circuit

Remove troubles caused by the potential

differences between the constant current

output and the GND, so that the GND po-

tential differences between the head unit

and the AMP is not overlapped in the AMP

to head unit communication.

●I2C buffer

Using an IC for I2C communication, be-

tween-AMP communication is conducted so

that there will be no trouble from GND po-

tential differences.
