Communications

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

Push-button Keypad Print

With a stable, in-range weight, press and hold for __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.

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

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):

Table 4-2. BMI Data

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.

Figure 4-1. Connection Ports

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.
