Serial communication
Serial communication allows to monitor system variables such as: generator and battery voltage, battery and load
currents, total system power and RPM value.
Serial protocol uses 83 bytes packet and send it one per second, Figure 15 shows the output string format. This protocol
is valid for GPU serial number starting from GPU0042. For older serial number, refer to the user manual version 1.4.
Variables are separated with 3 spaces. The output string example is:
Rpm=3400 Vgen=27.3 Vbatt=11.82 Ibatt=-1.3 I6v=1.2 I12v=0.8 Pout=16
Rpm – rpm value
Vlin – internal line voltage
Vbatt – battery voltage
Ibatt – battery current (negative value for charging)
I6v – load current at 6 V line
I12v – load current at 12 V line
Pout – total output power
Serial communication settings:
Baud rate 9600
Bits 8
No parity
