Table 3-4. Port Connection Locations

Communication

• The scale has a communication protocol: ESC protocol. An ESC protocol uses the escape (0X1B or ASCII 27) to indicate that there is a command following.
• On the computer, side there must be a listener created by the vendor that will interpret this protocol. This listener must also take care of all the issues regarding data integrity, etc., to make sure that the data sent and received is valid.
• Communication can be executed through either an RS232 I/O port or a USB I/O port.

The communication parameters are:

• 9600 baud (selectable in the programming mode)
• 8 data bits
• 1 stop bit
• No parity
• No handshaking
• For the USB connection, the USB driver installation will be on Windows® systems. The USB driver can be downloaded from the distributor and installation will be with the distributor’s guidance.
• The scale supports EMR protocol, and for additional information contact the distributor.

Print Button

• A long press will send data from both RS232 and USB ports. When data is transmitted out via a port the display flashes the word PRINT to acknowledge the data was sent.

In weight mode

• PATIENT WEIGHT 60.1 kg

In BMI (On calculated BMI display only)

• For kg Unit of Measurement.
• PATIENT WEIGHT 60.1 kg
• PATIENT HEIGHT 170.0 cm
• PATIENT BMI 20.8
• In case of underweight or overweight, the word UNDER or OVER will be sent accordingly.
