1.3 Connecting to Other Devices1

1.3.1 Connection to load cell

Connect thisindicator to load cell through the 9-pin load cell

connector located at the back. Refer to the below table for

load cell pin assignment.

① ② ③ ④ ⑤

⑥ ⑦ ⑧ ⑨

1Turn scale off and cut off power before making any connections or disconnections.

Short connect PIN 1 AND PIN 2, PIN 6 and PIN 7 when connected

to load cell with a 4-wire cable;

CAUTION

•Connection between load cell and indicator must be reliable;

shield-wire must be connected to ground reliably;

•Load cell and indicator are all

static-electricity-sensitive devices,measures must be

taken to ensure safety.

1.3.2 Connection to PC or SCOREBOARD or current display

(optional)

From the 15-pin interface located at the back, you could

•Connect indicator to computer via RS232 output or

RS422 output (optional);

•Connect indictor to scoreboard via 20mA current

•Connect indicator to computer via RS232 output or

Data format for RS232 or RS422 is the same. Data is transmitted

in ASCII code. Data format is as listed below(one group):

START DATA STOP

There are two modes to communicate with PC:

•Continuously send, and

•Command mode.

A. Continuously send

Data transmitted is tare weight or net weight from the display

of the indicator. Each time it sends one frame data to pc, one

frame consists of 9 groups while the data format of one group

is as listed above. Below is the content for one frame:

For example,

Now the indicator displays 50.00KG, then the frame indicator

sends to PC is : =+0050.00;

If the indicator displays -0.040KG, then the frame indicator

sends to PC is : =-000.040;

the calibration head performs.

Calibration head is a 15-pin connector with pin

DATA

Low digit

Indicator will act according to instruction from computer,

please refer to following notes and table:

AD: address of indicator (example A in ASCII code 41);

NN: address of memory pc wants to read/write;

C1: Content pc wants to read/write (000 digit);

C2: Content pc wants to read/write (00 digit);

C3: Content pc wants to read/writ (0 digit);

XH: Verify result for high 4 digits;

XL: Verify result for low 4 digits;

Notes:

•Address indicator could set is from 1~26, while

communication address is corresponding from A~Z;

•Instruction from A~Z is transferred in ASCII code;

but the example listed in table is in Hex. code. When

communicating with PC via the hyper terminal software(This

software is with windows operating system),you should

choose “transmit in hex format”, or else you must convert

the example to ASCII code;

•Instruction Q,R,S,T U is read/write operation for

data memory. There are many strings in data memory, but

one instruction from pc only triggers one operation, hence

several instructions should be sent from pc one by one

to do these operations

Instruction table is listed in appendix

•Connect indictor to scoreboard via 20mA current

loop output;

Data is transmitted serially in binary code with baud rate 600.

Data format is as listed below (one group):

0 1 2 3 4 5 6 7 8 9 10

START DATA(Low is prior to high) SIGN STOP

Indicator sends one frame data to scoreboard per 100ms, one

frame consists of 3 groups while the data format of one group

is as listed above. Below is the content for one frame:

For group one, Sign bit is 0; X(D0,D1,D2)means decimal point

(0~3); Y（D3）means sign(1 for negative while 0 for positive);

Y (D4) means display weight type( 1 for net weight while 0 for

tare weight); G17 and G16 is binary code;

For group two, Sign bit is 0; G15~G8 is binary code;

For group three, Sign bit is 1; G7~G0 is binary code;

From G0~G17 consists of 18 bit binary code, low prior to high.

•Connect indicator to current display via 4~20mA

analog output (optional)

When indicator is at zero,then current display will show 0;

when indicator is at the weight corresponding to 20mA, then

current display will show 20mA. (Refer to parameter setting

for how to set the weight corresponding to 20mA).

1.3.3 Connection with printer

25-pin interface
