1.0 Introduction
The Rice Lake Digital Handrail Scale is designed for weighing bariatrics and ensures sound, accurate weighing
information. A non-skid platform paired with side rails assists persons who need extra support and safety. The
scale is set up to use motion sensing weighing technology, to determine the actual weight of a moving patient.
The weight is displayed on the indicator and can be displayed in pounds or kilograms.
This manual can be viewed and downloaded from the Rice Lake Weighing Systems web site at

3.2 Repacking
If the Digital Handrail Scale must be returned for modification, calibration or repair, it must be properly packed
with sufficient packing materials. Whenever possible, use the original carton when shipping the scale back.
Damage caused by improper packaging is not covered by the warranty.
3.3 Setting Up Your Scale
Move the scale into the area where the weighing process will occur. Place the scale on a hard, level surface for
the most accurate weighments.
1. Locate the operator’s manual from inside the box and set aside as it will provide inst

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.
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:
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
either in motion, or out of range.

Figure 3-3 on page 4 shows where the RS-232 connection is.
• Pushbutton keypad print
• Escape protocol
• Maintenance protocol
PRINT. Note that if the scale does not beep after five seconds, then release the button as the weight was
• If displaying weight and not BMI, the scale will send out the following 21 character string:
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)
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:
<PATIENT><SP><WEIGHT><SP>-60.1<SP>KG<SP><CR><LF>
<PATIENT><SP><HEIGHT><SP>-170.0<SP>CM<SP><CR><LF>
<PATIENT><SP><B><SP><M><SP><I><SP><SP><SP><20.8<SP><SP><SP><SP><CR><LF>
Example in LB:
<PATIENT><SP><WEIGHT><SP>132.4<SP>LB<SP><CR><LF>

<PATIENT><SP><B><SP><M><SP><I><SP><SP><SP><20.4<SP><SP><SP><SP><CR><LF>
In case of under weight or over weight, the word Under or Over will be sent correspondingly.

7.2 Communication Protocols
The Rice Lake Digital Handrail Scale has two communication protocols, escape and maintenance protocol.
7.2.1 Escape Protocol
An escape protocol is where the escape (0X1B or ASCII 27) is used to indicate that there is a command
following. On the PC side there must be a 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 make sure that the data that was sent
and received is valid.
Two examples include:
• Scale initiated communication
• PC initiated communication

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 7-5.

Connecting software and downloads should be addressed by your IT department and can vary depending on what
type of computer platform you’re using. Basic information on USB driver installation using Windows® is
described in the following steps and serves only as an example. The USB driver can be downloaded from the
