5.3 RS232 Communication Interface - General Notes & DIP Switch
Settings
Eight-position dip switch, located to one side of the paper roll, is used to select and set the serial RS232
interface. The printer reads these switches once, on initial power-up. The functions assigned to each
switch are listed in Table 2.
Proper Baud Rate and protocol settings are required to communicate with a host computer. The standard
factory setting is 19,200 BAUD, 8 DATA BITS, NO PARITY BIT, and one STOP BIT, all switches in
off position.
