8 Digital Handrail Scale Operation Manual

5.0 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

System. Figure 5-1 shows where the RS-232 connection is.

The RS-232 parameters are 9600 baud (selec

table 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 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.

• If displaying weight and not BMI, the scale will se

nd out the following 21 character string:

xxxxxxxxx<SP>uu<SP>mm

mmm<SP><CR><L F>

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>

• 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

5.2 USB Connection

The Rice Lake Digital Handrail Scale has the capability of connecting to a PC using a USB connection and a

USB cable (not included). That connection location is shown in Figure 5-1.
