No.(1st and 2nd
letters)
R
Word
Read sensor unit Mfg. No. (8-letter
ASCII code)
Response example: When Mfg. No.
is ”C302026”, 1st letter is “C”, 2nd is “3”,
3rd is “0, …. 7th is “6” and 8th is
“(space)”
“C”=0x43 (high-order byte of word data)
“3”= 0x33 (low-order byte of word data)
“0”= 0x30 (high-order byte of word data)
“2”= 0x32 (low-order byte of word data)
“0”= 0x30 (high-order byte of word data)
“2”= 0x32 (low-order byte of word data)
“6”= 0x36 (high-order byte of word data)
