The unit comes with an RS-232 port which enables weight data to be transmitted to other devices. The RS-232 cable with DB-9 connector (PN 100719) is available from Rice Lake Weighing Systems, see Figure 4-1 on page 9 for RS-232 connections. The parameters of RS-232 are:

• 9600 baud (selectable baud rate)
• 8 data bits
• 1 stop bit
• No parity
• No handshaking
  There are three methods of communication:
• Pushbutton keypad print
• Standard remote protocol
• Escape protocol

4.1 Pushbutton Keypad Print

With a stable, in-range weight, press and holdfor at least three seconds, or until the scale emits two quick beeps.
Note: If the scale does not beep after five seconds, release as the weight was either in motion or out of range.

• The scale will send out the following 21 character string if displaying just weight and not BMI: 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)
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>

• The scale will send out the following data while in BMI mode (displaying the BMI value):
