SERIAL AND USB DEVICE PORT COMMANDS
The following commands and formats apply to both the Serial port and the USB Device port.
Both the Serial port and USB Device port on the MedVue weight analyzer are bi-directional
ports and can receive and transmit data. However, the USB Device port can only
communicate with a computer. The Serial port can output to a printer as well as communicate
to a computer.
Serial Port
Using the serial port, it is possible to control the printing operation of the MedVue weight
analyzer by transmitting commands to the indicator. Note that the RS232 MOdE parameter
must be set to 3 = Printer to allow this.
USB Device Port
In order for the computer to communicate to the indicator using the USB Device port, the
Remote computer requires the USB driver (MedVue.inf, available on the Detecto Dealer
Web Site) and the USb MOdE parameter must be set to 3 = Printer.
Print Command
The host device (computer) sends:
<LF> P <CR>
This command is equivalent to pressing the PRINT/ENTER key on the MedVue weight
analyzer keypad. The MedVue weight analyzer will respond by printing a ticket using the serial
port (or transmit data using the USB Device port). The ticket will be printed (or data
transmitted) in the following format:
