2.Connection of indicator pins and computer pins 3.Indicator and computer communication Weighing indicator continual send the current weight data to computer, 7 bytes a suite: the first is start bit (&HCD),other 6 bytes means the 6 digits weight,as the follow rule:(PS:&H means hex)
Not display data------&H0A Display weight--------display "8",the byte is &H08,display"8.",the first is 1,namely &H88 Minus---------------&H0B Lock "L"-------&H11 (dynamic G indicator can lock the data, the first digit is"L",the code is &H11)
Example:

2nd byte |

Example Programme(VB) 'Receiving 13 bytes from RS232' dim ss as Variant dim i,j as integer dim tmpstr as string ss = MSComm1.Input If LenB(ss) < 13 Then Exit Sub End If 'judge which byte the data start(algorism 205 is hex CD) While ss(i)<>205 and i<7 i=i+1 wend
'give up the data which has not 6 bytes after start bit if i>6 then exit sub
tmpstr="" for j=i+1 to i+6 If ss(j) <> 10 Then If ss(j) = 11 Then tmpstr = tmpstr & "-" ElseIf ss(j) > 127 Then tmpstr = tmpstr & CStr(ss(j) And 127) & "." Else tmpstr = tmpstr & CStr(ss(j)) End If End If next j
PS: the last tmpstr is the data that indicator sends to computer. 7 bytes is a weight data, the data is continually sent to computer, so this program gets 13 bytes every time to make sure there is one weight data. Customer can improve on it to match their requirement.
