12 RL-650 Series Neonatal Scale
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 (selectable in the programming mode), 8 data bits, 1 stop bit, no parity and
no handshaking.
The method to access weight data from the computer is:
• Pushbutton keypad print - Done by pressing and holding the
REWEIGH
key.
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 (
-)
neg 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>
5.2 USB Connection
The RL-650 has the capability of connecting to a PC using a USB connection and a USB cable. That connection
location is shown in Figure 5-1 .
