Output UART data format
The communication port has a serial format. The parameters are as follows:
UART:
9600 baud, 8 data bits, 1 stop bit, and no parity
Format:
There are 14 messages in the data stream
A typical message from the UART will be formatted as follows:
<6708,85.0,75.0,2,00000000,85.0,78.0,2,00000000,85.0,1800.0,45.00,40.00,249>
SD card data
The SD card contains data from the operation of the fuel cells.
SD card data designation
On the SD card there will be a folder called
Data
containing .csv files with the
columns having the following headings:
Power Path Module fault codes
The fault codes for the PPM as stored in the PPM SD card are shown below.
For fault codes from the FCPM SD card refer to the FCPM User Manual.
The naming of the unit is covered in N type rows. Serial number will be displayed as
a 15 digit alpha numeric. The software version will be displayed in the format X.XX.
