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 758C 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 758C by
transmitting commands to the indicator. Note that the PPORT parameter in the indicator
must be set to 1 = Serial Port to allow this.
USB Device Port
In order for the computer to communicate to the indicator using the USB Device port, the
computer requires the USB driver (758C_USB_Driver.inf, available on the Detecto Dealer
Web Site) and the PPORT parameter on the indicator must be set to 3 = USB Device Port.
Remote Print Command
The host device (computer) sends:
<LF> P <CR>
This command is equivalent to pressing the PRINT/ENTER key on the 758C keypad. The
758C 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:
If Pounds Only or Pounds/Kilograms
was selected for Unit=
If Kilograms Only, Kilograms/Pounds or Stones
and Pounds/Kilograms was selected for Unit=

Journal Mode Print Command
The host device (computer) sends:
<LF> J <CR>
This command is equivalent to pressing the PRINT/ENTER key on the 758C keypad. The
758C 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:
Weight, BMI, Height, Time, Date
NOTE: This command is equivalent to pressing the PRINT/ENTER key on the 758C
keypad with the P220 Serial Format Disabled and CRLF Enabled (P220=0), and the
CRLF set for Serial Format for P185 Journal Mode (Crlf=0) parameters selected. Note
that this command will print a ticket (or transmit data) in the above format regardless of
how the P220= and CrLF= parameters are set.
IMPORTANT! If ID or BMI are disabled, the field will be left out on any three formats.
