FAD - 4 DIGITAL LOADCELL JUNCTION BOX 02.05.00 FAD4_2RM 2 10 of 20
Master transmission:
STX ADD J 1 xxxxxx BCS2 BCS1 ETX
xxxxxx = 6digit PIN
Slave response:
STX ADD J 1 xxxxxx BCS2 BCS1 ETX
or NAK block if already locked.
THE VALUE IS NOT SAVED IN EEPROM UNTIL A STORE COMMAND IS ISSUED.
TO CHANGE PIN FIRST UNLOCK WITH THE OLD PIN THEN LOCK WITH THE NEW PIN.
BE CAREFUL WITH THE NEW PIN. IF IT IS LOST THE UNIT MUST BE RETURNED TO THE
FACTORY TO RECLAIM IT.
i. UPLOAD INTERNAL RESOLUTION
Uploads internal resolution of slave FAD-4.
Master transmission:
STX ADD i x BCS2 BCS1 ETX
where x : One digit defining the corner number (0-4). 0 = Sum of the corners.
1= Corner 1 , 2 = Corner 2 , 3 = Corner 3 , 4 = Corner 4.
Slave response:
STX ADD i x yyyyyy BCS2 BCS1 ETX
where x : One digit defining the corner number (0-4). 0 = Sum of the corners.
1= Corner 1 , 2 = Corner 2 , 3 = Corner 3 , 4 = Corner 4.
yyyyyy : 6 digits defining the data (ASCII decimal), of the respective corner.
P.
DOWN LOAD PARAMETERS
Used to download scale parameters. Because of the limited buffer size the scale parameters must
be sent in three groups P1, P2, P3.
Master transmission: (PAR 1)
STX ADD P 1 a b c d e f BCS2 BCS1 ETX
a : Conversions per sec : 1=8Hz/ n , 2=20Hz/ n , 3=40Hz/ n , 4=80Hz/ n. n=Nr of Loadcells.
MAXIMUM Conv/sec = 40Hz i.e. the 80Hz with one loadcell is not acceptable.
b : Gain set. 0 = 2 mV/V , 1 = 4 mV/V , for each input (Deadload + Span).
c : Number of loadcells (1, 2, 3, 4)
d : Weight units
0 = kg
e : Digital filter (0, 1, 2) 0 = 1 , 1 = 2 , 2 = 4 samples.
f : No motion samples (1, 2, 3, 4, 5, 6, 7) consecutive conversions within 0.5e.
Slave response :
STX ADD ACK or NAK BCS2 BCS1 ETX
A NAK block will be returned if some parameter is out of range.
