Dear Steve:
Thanks for contacting us.
According to the picture you send in the email, the UART returns command:
A5 5A 06 83 00 10 01 01 01
A5 5A: frame head
06: command length
83: read
00 10: variable address of your data entry log
01: data length
01 01: data (hex)
So the UART returns the hex value 0101, which is 257 (DEC).
Please notice that all the command is in hex format.
I hope this could answer your questions, and please let me know if you need to know anything else.
Kind Regards
STONEITECH
