1.0 Introduction

The RL-650 Series neonatal scale provides precise weighing of infants and neonates. The scale is equipped with

TM

Motiontrap

, a special motion sensing weighing technology, which compensates for involuntary movement
caused by an active infant. The infant’s weight can be displayed in pounds and ounces or kilograms and grams.
The weight is displayed until reweighing is performed or until the scale zeros out.

5.0 RS-232 Communication

USB Connection

RS-232 Connection

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 a DB-9 connector (PN 100719) is available from Rice Lake
Weighing Systems. Figure 5-1 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 to access weight data from a computer:

• Pushbutton keypad print - Done by pressing and holding the

• Standard remote protocol - See RL-650 Technical Manual, PN 167316

• Escape protocol - See RL-650 Technical Manual, PN 167316

5.1 Pushbutton Keypad Print

With a stable, in-range weight, press and hold the Reweigh key for at least three seconds. 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. The
print will show on the display when it is transmitting data.

If displaying weight, 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
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>

- sign, if negative uu is the unit (pound or kilogram).

5.2 USB Connection

The RL-650 Series neonatal scale has the capability of connecting to a PC using a USB connection and a USB
cable. See Figure 5-1.

Figure 5-1. USB Connection Port and RS-232 Connection Port

Connecting software and downloads should be addressed by the IT department and can vary depending on what
type of computer is being used. Basic information on USB driver installation using Windows

7.0 Maintenance

The following section provides instructions for maintaining and cleaning the RL-650 Series neonatal scale.
Maintenance operations other than those described in this section should only be performed by qualified service
personnel.

7.1 Basic Maintenance

Before the first use of the scale and after periods of non-use, check the scale for proper operation and function. If
the scale does not operate correctly, contact qualified service personnel.

Use the following steps for basic maintenance:

1. Check the overall appearance of the entire scale for any obvious signs of damage, abuse, etc.

2. Inspect the condition of the optional AC adapter for cord cracking or fraying, or for broken or bent
prongs.

7.2 Cleaning

Proper care and cleaning is essential to ensure a long life of accurate and effective operation. Before beginning
the cleaning process, disconnect the scale from the AC power source.

1. Clean all external surfaces with a clean, damp cloth or tissue. Mild soap and water solution may be used.
Dry with a clean soft cloth.

2. Do not immerse the scale into cleaning or other liquid solutions.

3. Do not use Isopropyl alcohol or other solutions to clean the display surface.
