12.1 Detailed protocol description in standard mode
LonG protocol
Transmission proceeds in the following way:
1. Communication parameters: 8 bits, 1 stop bit, no parity, baud rate 4800bps,
2. Available orders send from computer and balance answers:
 Readout of scale indication ( corresponds to pressing key
ComputerScale: S I CR LF (53h 49h 0Dh 0Ah),
ScaleComputer: scale response according to description below (16 bytes):
Byte

-
sign „-” or space
Byte

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 on www.axis.pl in computer
programs section) for scale number 1 please write: $0201 to log in, then SI, and write: $03 to close
communication.
 Asking for scale presence in system (testing scale connection with computer):
ComputerScale: S J CR LF (53h 4Ah 0Dh 0Ah),
ScaleComputer: M J CR LF (4Dh 4Ah 0Dh 0Ah),
 Displaying a sign on scale display (text message from computer):
ComputerScale: S N n n X X X X X X CR LF (53h 4Eh 0Dh 0Ah), nn-displaying time in
seconds; XXXXXX- signs to display
ScaleComputer: M N CR LF (4Dh 4Eh 0Dh 0Ah),
 Scale tarring (calling  T  key press) :
ComputerScale: S T CR LF (53h 54h 0Dh 0Ah),
ScaleComputer: without response,
 Scale zeroing (calling  0  key press):
Computer Scale: S Z CR LF (53h 5Ah 0Dh 0Ah),
Scale Computer: without response,
