Section 5…SerialRS232,IrDA and XMODEM
Communications
Select a serial RS232 or IrDA communication interface (see Figure1)
•The S2000iprinters support Serial RS232 and IrDA compatible infrared communication
interfaces.
•These interfaces are selected using DIP switches located on the printer control card,
located on the side of the paper supply.
•Refer to Table 2 for Dipswitch settings.
•Dipswitch #8 in the ON position selects IrDA interface. In the OFF position, serial
RS232 mode is selected.
lIf RS232 interface is selected, connect the data connector and setthe serial
communication parameters:Baud rate, number of Data Bit and Parity.
lIf using RS232 you also need a cable such asExtech part # 5892RJD9; this plugs into
the serial connector at the rear of the printer shown in Figure 2.
lPrinter drivers are available for Windows 95/98/NT/2000
lFor Windows CE devices, PrinterCE control application is available from
www.fieldsoftware.com.

Serial RS232C CONNECTIONS
lThe RS232C Interface signals for the S2000iprinter is
terminated on a 6 PIN RJ25 type data connector located at the
backof the printer.
lSix connections are provided from the Serial Interface to the
host computer. The table below lists the Serial Interface
signals and pin outson the RJ25 connector.
lPin locations are shown in Figure 1.A& 4. A minimum of
two connections are required for operation, RXD-pin3 and
Common-pin1. FIGURE 4 –Serial Connector

RS232 Communication Interface -General notes & DIP switch settings
§Eight-position dipswitch, 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.
The Extech Extended XMODEM protocol
The Extech XMODEM software option is designed to overcome the unreliability of data transmission
using direct infrared interface. It is intended for host computers equipped with IrDA compatible physical
interface and no IrDA software Stack.
The Extech XMODEM protocol is supported viaRS232 (RS-XMODEM) or IrDA (IR-XMODEM)
interface. The XMODEM option and the communication parameters are set using on boarddip switches, as
summarized in the table below.
