Frequently Asked Questions
What physical pins correspond to transmitting and receiving data?
TXD is assigned to Pin 2, and RXD is assigned to Pin 3.
What core settings should I configure for successful RS232 communication?
The recommended settings are a BaudRate of 19200bps, DataBits of 8bits, Parity None, and StopBits of 1bit.
How can I retrieve the current operating hours count?
Use the OperatingHour command code (Byte 1) and retrieve the data from Byte 2 (LSB) and Byte 3 (MSB).
If a command fails during execution, what status response should I look for?
A 'Success' response is indicated by 0x00 in the first byte. An invalid command returns 0x01, while an error returns 0x02.
