Rice Lake Digital Floor Level Scale Technical & Operating Instructions 15

7.0 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 3-2 on page 4 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

• Escape protocol

• Maintenance protocol

7.1 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, then 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:

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)

Example:

60.1 KG= <PATIENT><SP><WEIGHT><SP>-60.1<SP>KG<SP><CR><LF>

• In BMI mode (displaying the BMI value), the scale will send out the following data:

PATIENT WEIGHT 60.1 KG

PATIENT HEIGHT 170.0 CM

PATIENT BMI 20.8

Example in KG:

Example in LB:

In case of under weight or over weight, the word Under or Over will be sent correspondingly.
