7.2 Detailed LonG protocol description
Standard communication parameters: 8 bits, 1 stop bit, no parity, baud rate 9600bps,
After using
key, measurement data is send together with text description (NET, TARE, GROSS) – all
set by using Print option. If Print isn’t set then only scale indication is send (as below).
Data exchange (communication):

Readout of scale indication
Computer

Scale: SI CR LF (53h 49h 0Dh 0Ah),
Scale

Computer: scale response according to description below (16 bytes):
Byte 1 - sign „-” or space
Byte 2 - space
Byte 3 
4
- digit or space
Byte 5
÷
9 - digit, decimal point or space
Byte 10 - digit
Byte 11 - space
Byte 12 - k, l, c, p or space
Byte 13 - g, b, t, c or %
Byte 14 - space
Byte 15 - CR
Byte 16 - LF

Readout of actual indication
Computer

Scale: Sx1 CR LF – initiaton signal
Scale

Computer: scale sends 16 bytes (the same as SI commad)
 Readout of stabilization indicator and actual indication
Computer

Scale: Sx3 CR LF – initiaton signal
Scale

Computer: scale send indicator S (stable) or U (unstable) + 16 bytes (the same as SI
command).
Attention:
Network number different than zero ( SErIAL / nr function) changes scale working mode: communication
with a computer is possible after logging the scale in with 02h scale number command. To log the scale out
use 03h command.
For example: Using a program to test RS232 interface ( program is available in
www.axis.pl / programy
komputerowe ) for scale number 1 please write: $0201 to log in, then SI , and write: $03 to close
communication .

Asking about scale presence in system (testing scale connection with computer):
Computer

Scale: SJ CR LF (53h 4Ah 0Dh 0Ah),
Scale

Computer: MJ CR LF (4Dh 4Ah 0Dh 0Ah),
 Displaying a inscription on scale’s display (text communicate from computer):
Computer

Scale: SN n n X X X X X X CR LF, nn-displaying time in seconds; XXXXXX-6 signs to
display
Scale

Computer: MN CR LF (4Dh 4Eh 0Dh 0Ah),

Scale tarring (calling

T

key press) :
Computer

Scale: ST CR LF (53h 54h 0Dh 0Ah),
Scale

Computer: without response,
