Example:

@2,05<cr><lf>>0 is a response from command 2 that the CBC915 is in state 5.

Response 1: Power Available

<@> <command number> <comma> <XXXXX> <line feed> <carriage return> <zero>

XXXXX= ASCII numbers for microwatts of power (1-99999)

Example: Command request for power available #<sp>1<cr> ;where <sp> = ASCII space character and

<cr> = ASCII carriage return character

Command returns @1,00237<cr><lf>0 Where 00237 is 237uW of power available and <lf> is ASCII

line feed character

Response 2: State of CBC915

<@> <command number> <comma> <XX><carriage return> <line feed> <zero>

XX= ASCII numbers for State (1-99)

State 1 = MPPT mode

State 2 = Capacitor charging

State 3 = EnerChip(s) charging

State 4 = System in regulation

State 5 = Output off

Response 3: Transducer Type

<@> <command number> <comma> <XX> <carriage return> <line feed> <zero>

XX= ASCII numbers for transducer type (1-99)

Transducer 1 = Low voltage input; typically TEG

Transducer 2 = PV cell input

Transducer 3 = High voltage input; typically piezoelectric

Transducer4=Mediumvoltageinput,constantimpedance transducers;typicallyelectromagnetic

generators

Response 4: Find Maximum Peak Power Point

<@> <command number> <comma> <ack> <carriage return><line feed> <zero>

<ack>= ASCII ACK

Response 5: EnerChip State of Charge

<@> <command number> <comma> <XXX><carriage return> <line feed> <zero>

XXX= ASCII numbers as percent of full charge (requires command to be requested twice for accurate

data)

Response 6: Calibrate EnerChip EP.

<@> <command number> <comma> <XXXX> <carriage return> <line feed> <zero>

XXXX= ASCII numbers for A/D reading for 4.06 volts

Response 7: Returns data from Command 1, Command 2, Command 3, and Command 5

<@> <command number> <comma> <XXXXXYYZZUUU> <carriage return><line feed> <zero>

X = ASCII numbers for POWER

Y = ASCII numbers for STATE

Z = ASCII numbers for TRANSDUCER TYPE

U = ASCII numbers for ENERCHIP percent charge
