2.Connection of indicator pins and computer pins
3.Indicator and computer communication
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,display8.,the first is 1,namely &H88
Minus---------------&H0B
Lock L-------&H11 (dynamic G indicator can lock the data, the first digit isL,the code is &H11)
Example:
| weight | 1st byte |
2nd byte |
3rd byte |
4th byte |
5th byte |
6th byte |
7th 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.
