Data Format
Above 12byte consist by 6 byte hexadecimal digits,<SP>,0x70 0x70 0x6D, <CR><LF> , where
decimal ‘0’ (corresponds to hexadecimal digit ‘0x30’) is replaced by space (corresponds to
hexadecimal digit ‘0x20’),
EX) 1,255 ppm, results ‘0x20 0x20 0x31 0x32 0x35 0x35 0x20 0x70 0x70 0x6D 0x0D 0x0A’, which
displays ‘__1255_ppm<CR><LF>’on screen.
In need of detail command set, ‘U-ART String Command Guide ’ could be provided by
contacting Sales Rep.
