36 Scale Link 2 Technical Manual D4204-EN
The serial gross weight data can be sent at any available baud rate, 1 start bit, 7 or 8 data bits,
EVEN, ODD, or NONE parity bit, and 1 stop bit on pin 2 (COM #1 Tx line) or pin 4 (COM #2 TX line)
on the Serial / Printer connector.
See Port Settings Menu 2.2 for more information.
• Starts with <STX> (Start of Text)
• Six digit Serial Gross Weight “whole number” value (ie.1000 not 100.0)
"LB" or "KG" unit of measure.
• Space character.
LINE STATUS (Five potential messages)
• “EB” – ZEROUT has not been performed.
• “ES” – Indicator currently in a menu
• “ER” – Indicator in an OVERCAP or RANGE message
• “SC” – Internal calibration is taking place
• "SG" – Serial Gross weight.
• The <ETX> (End of Text) control character.
• Checksum Character (C) value that includes all bytes starting after the <STX> up through, but
not including the <ETX>.
• Ends with a <CR> (Carriage Return)
Output example:
<STX>999999LB EB<ETX>i<CR>
Value is calculated using a "serial zero/balance point" (ZEROUT D.A.N. 2102) and may not
match the weight displayed on the scale. The serial gross weight is not affected when the operator performs a
normal zero/balance. The serial gross weight value will always be gross and does not change when the
operator performs a normal zero/balance or selects the Net or Load/Unload weight to be displayed.
12 Transmit comma delimited data which includes the "displayed gross weight" 10 times per second.
(Format follows SCOREM 11)
Output example:
<STX> 670LB SG<ETX>j<CR>
14 Transmit weight displayed, and tons per acre 1 time per second.
• Starts with <STX> (Start of Text)
• Six digit displayed weight value (may include a decimal).
