Rice Lake Digital Physician Scale — RS-232 Communication 11
5.0 RS-232 Communication
The scale comes with an RS-232 port that 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 3-9 on page 7 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
5.1 Pushbutton Keypad Print
With a stable, in-range weight, press and hold the
LB/KG/Print
key for at least three seconds, or until the scale
displays
PRINT
. Note that if the scale does not beep after five seconds, release the button as the weight was either
in motion or out of range.
• If displaying weight and not BMI, the scale will send out the following 21 character string:
xxxxxxxxxuummmmm
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 = -10.0lbNet
10 Lb gross = -10.0lbGross
• In BMI mode (displaying the BMI value), the scale will send out the following data:
GROSS WEIGHT 215.0 LB
TARE WEIGHT 0.0 LB
NET WEIGHT 215.0 LB
PATIENT HEIGHT 6-01.0 FT
PATIENT BMI 28.4
