Setting Up the Host

RS-232 Settings

In order for the host computer to communicate with the

LabelWriter SE300 printer, the communication parameters must

be set as follows:

•= Baud Rate: 9600

•= Data Bits: 8

•= Stop Bits: 1

•= Parity: None

On a computer running DOS, you can use the MODE command

to configure a serial port. To do this, type the following at the

DOS prompt:

MODE COM#: 96,N,8,1,P

where COM# is the serial port you are using. This could be

COM1, COM2, or any valid COM port.

Most compilers provide a command or function to initialize a

serial port. In the BASIC programming language, use the

following command:

OPEN “COM:9600,N,8,1” FOR OUTPUT AS #1

In Microsoft C/C++, use the function:

bios_serialcom().

Other C compilers offer a similar function. Consult your compiler

user guide for the appropriate function to use to configure a serial

port.

If you are using the Unix OS, you’ll need to configure the RS232

port as a dumb printer port, with no special handling, control

characters or form feeds. The LabelWriter will handle these

functions internally.
