Changing Printer’s Serial Baud Rate Settings
Some embedded systems have serial ports with slow baud rates. And sometimes these baud rates are
incompatible with the default baud rates of the Smart Label Printers. The 440 and 450 printers have an
EEPROM that can store the default baud rate that the printer should use when it powers up. Within the
standard application install is a program called “SlpSelect.exe”. Executing SlpSelect.exe as described
below will present a private interface for changing the baud rate of attached printers.
1.
Attach an SLP 440 or SLP 450 to the serial port of your computer. (
The USB cable should
not be attached.)
If your printer did not come with a serial cable please contact support. You
may qualify for a free serial cable from Seiko Instruments USA Inc.
2.
Execute SlpSelect.exe /default [port] [baudrate]
a.
port is one of
COM1, COM2, COM3 or COM4
b.
baudrate is
9600, 19200, 38400, 57600, 115200
For example:
> SlpSelect.exe /default COM1 9600
3.
Follow the instructions on-screen.
Factory baud rate for the SLP 440 is 115,200. Factory baud rate for early SLP 450 models is 38,400
and 115,200 for later models.
