9.5 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
Byte 2
Byte
34
Byte 5÷9
Byte 10
Byte 11
Byte 12
Byte 13
Byte 14
Byte 15
Byte 16
 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
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
ComputerScale: ST CR LF (53h 54h 0Dh 0Ah),
ScaleComputer: without response,
