Now configure the Baud rate (Speed) of the RS232 to be as fast as possible (19200 in my case) Please note that the length of the RS232 cable effects the reliable speed of communication. You would need WinWedge for multiple scales. 0000045711 00000 n This should start the server and display the following: Now open UAExpert and press the + icon in the tool bar to add a new server, Now double click the Add server text and enter localhost:4335. 0000014268 00000 n V endstream endobj 68 0 obj 122 endobj 35 0 obj << /Type /Page /Parent 19 0 R /Resources 36 0 R /Contents [ 44 0 R 46 0 R 48 0 R 54 0 R 56 0 R 58 0 R 60 0 R 63 0 R ] /MediaBox [ 0 0 595 842 ] /CropBox [ 0 0 595 842 ] /Rotate 0 >> endobj 36 0 obj << /ProcSet [ /PDF /Text /ImageC /ImageI ] /Font << /F1 40 0 R /F2 38 0 R /F4 52 0 R >> /XObject << /Im1 61 0 R >> /ExtGState << /GS1 64 0 R >> /ColorSpace << /Cs6 39 0 R /Cs9 42 0 R >> >> endobj 37 0 obj << /Type /FontDescriptor /Ascent 718 /CapHeight 718 /Descent -207 /Flags 32 /FontBBox [ -166 -225 1000 931 ] /FontName /Helvetica /ItalicAngle 0 /StemV 88 /XHeight 523 /StemH 88 >> endobj 38 0 obj << /Type /Font /Subtype /Type1 /FirstChar 32 /LastChar 169 /Widths [ 278 278 355 556 556 889 667 191 333 333 389 584 278 333 278 278 556 556 556 556 556 556 556 556 556 556 278 278 584 584 584 556 1015 667 667 722 722 667 611 778 722 278 500 667 556 833 722 778 667 778 722 667 611 722 667 944 667 667 611 278 278 278 469 556 333 556 556 500 556 556 278 556 556 222 222 500 222 833 556 556 556 556 333 500 278 556 500 722 500 500 500 334 260 334 584 350 0 350 222 556 333 1000 556 556 333 1000 667 333 1000 350 611 350 350 222 222 333 333 350 556 1000 333 1000 500 333 944 350 500 667 278 333 556 556 556 556 260 556 333 737 ] /Encoding /WinAnsiEncoding /BaseFont /Helvetica /FontDescriptor 37 0 R >> endobj 39 0 obj [ /ICCBased 66 0 R ] endobj 40 0 obj << /Type /Font /Subtype /Type1 /FirstChar 32 /LastChar 252 /Widths [ 278 333 474 556 556 889 722 238 333 333 389 584 278 333 278 278 556 556 556 556 556 556 556 556 556 556 333 333 584 584 584 611 975 722 722 722 722 667 611 778 722 278 556 722 611 833 722 778 667 778 722 667 611 722 667 944 667 667 611 333 278 333 584 556 333 556 611 556 611 556 333 611 611 278 278 556 278 889 611 611 611 611 389 556 333 611 556 778 556 556 500 389 280 389 584 350 0 350 278 556 500 1000 556 556 333 1000 667 333 1000 350 611 350 350 278 278 500 500 350 556 1000 333 1000 556 333 944 350 500 667 278 333 556 556 556 556 280 556 333 737 370 556 584 333 737 333 400 584 333 333 333 611 556 278 333 333 365 556 834 834 834 611 722 722 722 722 722 722 1000 722 667 667 667 667 278 278 278 278 722 722 778 778 778 778 778 584 778 722 722 722 722 667 667 611 556 556 556 556 556 556 889 556 556 556 556 556 278 278 278 278 611 611 611 611 611 611 611 584 611 611 611 611 611 ] /Encoding /WinAnsiEncoding /BaseFont /Helvetica-Bold /FontDescriptor 41 0 R >> endobj 41 0 obj << /Type /FontDescriptor /Ascent 718 /CapHeight 718 /Descent -207 /Flags 262176 /FontBBox [ -170 -228 1003 962 ] /FontName /Helvetica-Bold /ItalicAngle 0 /StemV 140 /XHeight 532 /StemH 140 >> endobj 42 0 obj [ /Indexed 39 0 R 255 65 0 R ] endobj 43 0 obj 1022 endobj 44 0 obj << /Filter /FlateDecode /Length 43 0 R >> stream 0000008429 00000 n 0000005246 00000 n Amazon.com also sells them for around $10. This is supposed to tell you if the serial port is connected or not but doesnt appear to function as it should. Requires a PC / MAC / Raspberry Pi to be located close by. 0000162777 00000 n Most scales will typically connect to a PC using a Null Modem cable however there are exceptions. All of the Mettler Toledo scales use a communication protocol called MT-SICS (Mettler Toledo Standard Interface Command Set) which is detailed here. Another Question: I I were to use 10 scales would each one input its values into a separate excel sheet or could I make them put all of the data in one sheet? 0000009845 00000 n 0000161697 00000 n 0000148820 00000 n Both are correct.cheersBlindphoton (Bill)BSc, MRACS, Chartered Chemist, Reply This section will contain a list of all COM ports that are installed on your PC.
