CHAPTER 1: INTRODUCTION

The 232SPS2 is a bi-directional parallel to serial converter. The
232SPS2 allows you to convert data from your parallel port to a
serial communication format or to convert data from your serial port
to a parallel communication format. Standard baud rates from 1200
to 115.2k with a variety of data formats can be used to match the
user's serial port requirements. Both kinds of flow control,
XON/XOFF and hardware handshaking, are supported by this unit.

The unit may be port-powered using DTR and RTS on the serial
port. If the 232SPS2 cannot be powered using the handshake lines,
it may be powered using a 2.5mm jack. The 232SPS2 requires
12VDC @ 2 milliamps.

NOTE: When using an external supply, the supply should be
connected only to specifically labeled power inputs (power
jack, terminal block, etc.). Connecting an external power
supply to the handshake lines may damage the unit. Contact
technical support for more information on connecting an
external power supply to the handshake lines.

CONNECTING THE 232SPS2 TO YOUR PARALLEL PORT

The 232SPS2 uses most of the available pins on the parallel
port. To insure proper operation, you should use a cable that
connects all 25 pins from connector to connector. B&B's Model
232AMM5 is recommended. For detailed information on which pins
are connected on the parallel port, refer to Appendix A.

CONNECTING THE 232SPS2 TO YOUR SERIAL PRINTER

The connections required between your 232SPS2 and your
serial printer depend on the type of flow control used. There are two
kinds of flow control, XON/XOFF control and hardware handshaking
control. Dipswitch position #4 must be "OFF" for XON/XOFF control.
Dipswitch position #4 must be "ON" for DTR handshaking. For more
detailed information on serial port connections, refer to Appendix B.

CHAPTER 3: SERIAL TO PARALLEL
INSTALLATION

When converting data from your serial port to a parallel
communication format, position #8 of the dipswitch must be "OFF".
The other seven positions should be set to match the data format of
your computer's serial port. Refer to Table 5.1 for dipswitch setting
specifications.

CONNECTING THE 232SPS2 TO YOUR PARALLEL PRINTER

The 232SPS2 has a DB-25 female connector on its parallel port.
Most parallel printers use a Centronics 36-pin connector. To insure
proper operation, you should use a cable that connects all 25 pins
from the DB-25 connector to the appropriate pins on a Centronics
36-pin connector. B&B's Model CPC is recommended. For detailed
information on which pins are connected on the parallel port, refer to
Appendix A.

CONNECTING THE 232SPS2 TO YOUR SERIAL PORT

The connections required between your 232SPS2 and your
serial port depend on the type of flow control used. The type of flow
control used depends on the software you are using. If you are
unsure which type of flow control your software uses or if you plan to
run different kinds of software, you should use a cable that connects
all 9 pins from connector to connector and set the handshaking
mode to be XON/XOFF control. In this mode both DTR handshaking
and XON/XOFF control are used for flow control. Dipswitch position
#4 should be "OFF" for XON/XOFF control. For more detailed
information on serial port connections, refer to Appendix B.

CHAPTER 4: POWER CONNECTIONS

The unit may be port-powered using DTR and RTS on the serial
port. If the 232SPS2 cannot be powered using the handshake lines,
it may be powered externally using +7 to +18 volts DC at 2
milliamps. If you are using an external supply, simply plug a 2.5 mm
plug from an appropriate DC source into the power jack on the side
of the 232SPS2 module. Power supplies are available through B&B.
(Model 232PS is recommended.)

CHAPTER 5: SELECTING DIPSWITCH SETTINGS

The 232SPS2 is set up using an eight-position dipswitch. In
order for the 232SPS2 to function properly, it must be set up to
match your system's requirements. The following parameters on the
232SPS2 are set on the dipswitch: converter direction, baud rate,
flow control, number of data bits, and the type of parity. Each of the
parameters are briefly described below. For specific parameter
settings, refer to Table 5.1.

Converter direction - Can operate as a parallel to serial
converter or as a serial to parallel converter. The direction is
set by dipswitch position 8.

Baud rate - Can be set from 1200 to 115.2k baud. The baud
rate is determined by dipswitch positions 1-3.

Flow control - Can be set for DTR control or XON/XOFF
control. The type of flow control used is determined by
dipswitch position 4.

Data bits - Can be set for 7 or 8 data bits. The number of
data bits is determined by dip s witch position 5.

Parity - Can be enable or disabled by dipswitch position 6. If
parity is enabled, dipswitch position 7 determines whether
the parity is even or odd.

APPENDIX A: PARALLEL PORT CONNECTIONS

The parallel port connections for the parallel to serial and serial
to parallel mode are shown in Table A-1, and Table A-2,
respectively. The connections required are the same for both modes
of handshaking. The error lines on the parallel port are forced to the
"no error" states. If the printer is off-line, out of paper, etc., the
232SPS2 will force the busy line (Pin #11) on the parallel port high
(logic "1") when in parallel to serial mode. If a error occurs in serial
to parallel mode, the XOFF character will be sent or DTR will be
lowered depending on type of flow control used. (NU - Indicates a
signal is not used or is not “passed through”)

APPENDIX C: SOFTWARE HINTS

PARALLEL TO SERIAL MODE

In parallel to serial mode, data from the computer is output
through the parallel port. The 232SPS2 will send the data to the
serial printer. The following command can be entered at the DOS
prompt to send a data out the parallel port:

PRINT filename

This command will output filename out the parallel port. The
first time that this command is executed, you will be prompted for the
PRN device (LPT1, LPT2, etc. ). For this device, you should enter
the parallel port that the 232SPS2 is connected. The default device
is LPT1.

SERIAL TO PARALLEL MODE

In serial to parallel mode, data is output through the serial port.
The 232SPS2 will send the data to the printer. Before data can be
sent out the serial port, you must set up the communications to
match the serial port settings of the 232SPS2. Your serial port's
communications can be set using the "MODE" command as follows:

MODE COMn: b,p,s,r

The syntax options for the MODE command are:

COMn The port to be configured. COM1, COM2 are
two common examples.
b The baud rate setting. 12=1200, 24=2400,
48=4800, 96=9600, & 19=19200 baud
p The parity setting. N=none, E=even, O=odd.
s The number of stop bits. Must be set to "1".
r Type of retry of time-out error occurs.
e = Return busy port error.
b = Return busy port "Busy"
p = Continue retry until printer accepts data
r = Return "Ready" from busy port
n = Disable retry (Default)

If the 232SPS2 is set for 9600 baud, parity disabled, 8 data bits
and is connected to COM1, the MODE command parameters would
be as follows:

MODE COM1: 96,n,8,1,p

If any of the parameters are omitted, the most recent setting will
be used. It is recommended that the "p" option be used for the retry
option. If the "p" is not used, a device busy error may occur. To
send data out the serial port, the following command can be entered
at the DOS prompt:

TYPE filename > COM1

This command will send filename out COM1.
