3.5 Troubleshooting

Refer to the following table to check and correct any failure before contacting service personnel.

4.0 Communication

The unit 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. That connection is shown in USB Connection section on the next page.

The RS-232 parameters are:

• 9600 baud (selectable in the programming mode)
• 8 data bits
• 1 stop bit
• no parity
• no handshaking

There are three methods of communication:

• Push-button keypad print
• Standard remote protocol
• Escape protocol

4.1 Push-button Keypad Print

With a stable, in-range weight, press and hold the Print button for at least three seconds, or until the scale emits two quick beeps.

NOTE: If the scale does not beep after five seconds, release the Print button as the weight was either in motion or out of range.

If displaying weight and not BMI, the scale will send out the following 21 character string: xxxxxxxxuummmmm

Example:

-10 Lb net = -10.0lbNet

10 Lb gross = 10.0lbGross

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

4.2 USB Connection

The scale has the capability of connecting to a Windows® computer (PC) using a USB cable (not included) and a terminal emulation program. A terminal emulation program allows the transfer of data between the scale and PC using a serial port.

A diagram shows the USB and RS-232 connection ports on the scale indicator.

NOTE: Apple® and Macintosh® computers are unable to transfer the necessary data to the scale. Only use a PC for data transfer.

Connecting software and downloads should always be addressed by the IT department for safety reasons and can vary depending on what type of computer platform is being used.

NOTE: Consult the IT department if driver protections are preventing the use of the USB driver. Driver protections may need to be temporarily disabled on Windows 10 or later computers to allow for the installation of the USB driver.

1. Connect the scale's indicator to a PC using a USB-Type B to USB-Type A cable (not included).
2. Turn the indicator on.

NOTE: In most cases, the PC should find the driver and automatically configure the driver when the scale is plugged into a USB port.

3. Open a terminal emulation program, such as Advanced Serial Port Terminal, PuTTY or Hercules (used in this example).
4. Connect to the serial port assigned by the PC (COM5 in example). This can be found in Device Manager. Once selected, press Open.

Diagrams show Device Manager and the Hercules SETUP utility, illustrating how to connect to a serial port.

5. With weight on the scale, press and hold the Print button on the indicator for three seconds. The patient's weight is sent to the PC.

A diagram shows the Hercules SETUP utility displaying patient weight data.
