[. . . ] SW1 -6 No parity Odd parity Even parity OFF ON OFF ON SW1-7 OFF ON ON OFF Note: All DIP switch selections should be performed with the power OFF. 25 DIP SWITCH SETTING The Epson 420i has two banks of eight DIP switches located on the back of the printer next to the interface connectors. The switch banks are labeled 1 and 2, with the individual switches in each bank labeled from 1 to 8. To identify a particular switch we use a two part number consisting of the bank number followed by the switch number. For example, 2-4 identifies the fourth switch from the top in bank number 2. BANK 1 BANK 2 DIP switches. All DIP switch selections should be performed with the power OFF. The switches are located at the rear of the printer next to the input connector. As shipped from the factory, all switches are turned OFF. DIP Switch Bank 1 DIP Switch Bank 1 controls the selection of the interface that you want to use. If you are using a parallel interface, then you should be able to leave this bank of switches alone (they should be all set to OFF). If you are using the serial (RS-232-C) interface, then the settings of this bank of switches must be set to match the serial interface settings of your computer. · Interface and Protocol Selection * Number of Data Bits Selection 26 * Baud Rate Selection * Parity Selection * Parity Error Selection DIP Switch Bank 2 This bank of switches selects some of the other features of the Epson 420i. These switches may be left in the OFF position as they come from the factory, or you may wish to change some of the switch settings to select different features. First you must decide if you want to use the Epson FX mode or the IBM Graphics Printer mode, determined by Switch 2-4. * LF (Line Feed) Command Selection A carriage return is executed when the printhead returns to the print start or left margin position. * CR (Carriage Return) Command Selection Auto-CR Execute a carriage return upon receiving a line feed Disabled Enabled OFF ON SW 2-2 If SW2-1 and SW2-2 are both set on ON, the CR command and the LF command perform the same function. 27 * Skip-over Perforation Selection Skip Perforation Skip-over perforation Disabled Enabled SW 2-3 OFF ON * Operating Mode Selection Printer Mode Select operating mode Epson Printer IBM Graphics Printer SW 2-4 OFF ON Note: Switch 2-4 changes several functions of the printer.
