AE & AEK Series Communication Protocol

bit 4 SMPS Fail.
0 = SMPS works normal.
1 = Unit fail,
bit 3 Fan Fail.
Power shutdown.
0 = Fan works normal
1 = Fan fail, Power shutdown.
bit 2 OTP Shutdown.
0 = Normal Internal temperature.
1 = Internal temperature is over 85
O
C, Power shutdown.
bit 1 OLP Shutdown.
0 = Normal
1 = Overload shutdown.
bit 0 OVP Shutdown.
0 = Normal.
1 = Overvoltage shutdown.
4-5 Status: 1 readback
To read value of [0x6F] and convert the value into Binary code
bit 7 Remote Control Status
0 = Control by VCI, ACI, ENB
1 = Control by software (I
2
C or RS-232 / 485)
bit 6, 5 Unimplemented, Read as '0'.
bit 4 Power Control Status
0 = Power OFF
1 = Power ON
bit 3, 2 Unimplemented, Read as '0'.
bit 1 CDM Active
0 = CMD<0.3V
1 = CMD>0.5V
Please refer to spec. sheet CMD vs. O/P curve graph per datasheet indication
bit 0 Inhibit by control Signal (In Local mode[0x7C.7]=0 only)
0 = SMPS works normal
1 = Inhibit by VCI, ACI or INHI signal.
5. Control Command and Calculation Example
5-1 Output voltage setting
To multiply the setting voltage of 100 and convert the value into hex code, please write
High byte first followed by Low byte on the addresses of 0x71, 0x70.
Ex: To set output voltage to 24.25V, please multiply 24.25 by 100, then convert 2425 in
to Hex code. Write hex code of 0x979, 0x09, 0x79 into the addresses of 0x71, 0x70.
