AE & AEK Series Communication Protocol

8-2-11 Output Current Query
Syntax: RI?
Parameter: None.
Description: To query the output current value
8-2-12 Internal Temperature query
Syntax: RT?
Parameter: None.
Description: Query the internal temperature value of SMPS. SMPS will transmit the
internal temperature value. The internal temperature info is provided in °C.
8-2-13 Control mode Select / Query
Syntax: REMS <type>
Parameter: 0 <= type <= 2
Description:
<type> = 0: Control mode will be set to LOCAL->The voltage and current of SMPS are set
by VCI and ACI, and control Power ON/Off by ENB.
<type> =1: Control mode will be set to REMOTE->The voltage and current of SMPS are set
by SV and SI, and control Power ON/Off by command POWER, GLOB.
<type> =2: Query the control mode, the device will transmit “0” to express LOCAL or “1”
to express REMOTE.
8-2-14 Device Status Query
Syntax: STUS <type>
Parameter: type = 0 or 1
Description: Query the device status, the device will transmit two ASCII characters to
express an 8 bit Hex code and transform it to Binary code. Definition as show below:
<type> = 0 : Bit-0 -> OVP Shutdown.
Bit-1 -> OLP Shutdown.
Bit-2 -> OTP Shutdown.
Bit-3 -> FAN Failure.
Bit-4 -> AUX or SMPS Fail.
Bit-5 -> HI-TEMP Alarm.
Bit-6 -> AC Power De-rating
Bit-7 -> AC input failure.
<type> = 1 : Bit-0 -> Inhibit by VCI / ACI or ENB.
Bit-1 -> CMD Active.
Bit-2 -> (Not used.)
Bit-3 -> (Not used.)
Bit-4 -> (POWER)
Bit-5 -> (Not used.)
Bit-6 -> (Not used.)
Bit-7 -> (REMOTE)
