USER MANUAL 55_________________________________________________________________________________________________________________17. Detailed information about balance communicationBelow important information about serial ports.17.1 Long protocol descriptionTransmission proceeds in the following way:1. Communication parameters: 8 bits, 1 stop bit, no parity, baud rate 9600bps,2. Available orders send from computer and balance answers: Readout of scale indication ( corresponds to pressing keyComputerScale: S I CR LF (53h 49h 0Dh 0Ah),ScaleComputer: scale response according to description below (16 bytes):Byte 1 - sign „-” or spaceByte 2 - spaceByte 34 - digit or spaceByte 5÷9 - digit, decimal point or spaceByte 10 - digitByte 11 - spaceByte 12 - k, l, c, p or spaceByte 13 - g, b, t, c or %Byte 14 - spaceByte 15 - CRByte 16 - LFAttention:Network number different than zero (SErIAL / nr function) changes scale working mode: communicationwith a computer is possible after logging the scale in with 02h scale number command. To log the scale outuse 03h command.For example: Using a program to test RS232 interface ( program is available on www.axis.pl in computerprograms section) for scale number 1 please write: $0201 to log in, then SI, and write: $03 to closecommunication. 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 inseconds; XXXXXX- signs to displayScale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),
