6 Platform Fitness Operation Instructions
4.0 RS-232 Communication
The scale comes with an RS-232 port which enables weight data to be transmitted to other equipment, such as a
computer or printer. The RS-232 cable with DB-9 connector (PN 100719) is available from Rice Lake Weighing
Systems. Figure 2-1 on page 2 shows where the RS-232 connection is.
The RS-232 parameters are 9600 baud (selectable in the programming mode), 8 data bits, 1 stop bit, no parity
and no handshaking.
There are three methods of communication:
• Pushbutton keypad print
• Standard remote protocol
• Escape protocol
4.1 Pushbutton Keypad Print
With a stable, in-range weight, press and hold the Kg-Lb/Print key for at least three seconds, or until the scale
emits two quick beeps. Note that if the scale does not beep after five seconds, then release the button as the
weight was either in motion, or out of range.
• The scale will send out the following 21 character string:
xxxxxxxxx<SP>uu<SP>mmmmm<SP><CR><LF>
Where:
xxxxxxxxx is the weight with decimal point and " - " sign, if negative uu is the unit (lb or kg).
mmmmm is the mode (gross or net)
Examples:
-10 Lb net = <SP><SP><SP><SP>-10.0<SP>lb<SP><SP>Net<SP><SP><SP><CR><LF>
10 Lb gross = <SP><SP><SP><SP><SP>-10.0<SP>lb<SP>Gross<SP><CR><LF>
