4.0 Communications
The indicator 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 4-3 on
page 12 shows where the RS-232 connection is located on the indicator.
Always use medical grade isolators for USB and RJ45 when connected to non-medical equipment, or when
other medical equipment is connected to patient during procedure.
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
4.1 Pushbutton Keypad Print
With a stable, in-range weight, press and hold for at least three seconds, or until the scale emits two quick beeps.
If the scale does not beep after five seconds, release the button as the weight was either in motion, or out of
range.
In the weigh mode, the scale sends the 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:
-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 sends the following data:
GROSS WEIGHT 215.0 LB
TARE WEIGHT 0.0 LB
NET WEIGHT 215.0 LB
PATIENT HEIGHT 5-01.0 FT
PATIENT BMI 30.1
4.2 Escape Protocol
The escape protocol uses the escape (0X1B or ASCII 27) to indicate that a command is following. On the PC side there must
be a software listener created by the vendor that will interpret this protocol. This listener must also take care of all the issues
regarding data integrity, etc. to ensure the data sent and received is valid.
Two examples include:
• Scale initiated communication
• PC initiated communication
PC Initiated ESC Value
Request current values/settings R
Diagnostics A
Send scale control messages C
