Overview

The SXP-320A / SXP-325A are interface converters that

allow Centronics and RS-232 devices to communicate

with each other (a computer with an RS-232 output to a

Centronics printer, for example).

Both units are bidirectional enabling you to convert from

serial to parallel or parallel to serial. The primary diﬀerence

between them is that the SXP-325A is conﬁgured with 512

KB of memory allowing it to serve as a printer buﬀer,

whereas the SXP-320A has no memory.

These two way converters provide a DB-25 RS-232C (DCE)

compatible connector, and a C-36 Centronics connector.

The serial baud rate is from 1200 to 115200 bps. (selectable

by DIP Switch). The parallel interface speed for the (non-

buﬀered) SXP-320A is 11.52 KB/sec; for the (buﬀered) SXP-

325A, it is 1.5 MB/sec.

The units support both hardware and software (XON/XOFF)

handshaking. Setup is extremely easy. All that is involved

is setting the DIP Switch and connecting the cables.

Installation

Switch Conﬁguration Overview:

The SXP-320A/325A is conﬁgured by setting an eight

segment DIP Switch as follows:

An explanation of each DIP Switch setting is given below.

Note: 1. When the segment is set in the direction of the

arrow, it is ON.

2. In each table, the default setting is highlighted

Conversion Direction:

Cabling

Serial to Parallel:

When performing a Serial to Parallel interface conversion:

1. Plug the female end of a 25/9-pin to 25/9-pin

male/female serial cable into the PC's serial port

2. Plug the male end of the 25-pin to 25-pin male/female

serial cable into the SXP-320A/SXP-325A's serial

connector

3. Plug the female end of a C-36 to C-36 male/female

printer cable into the SXP-320A/SXP-325A's printer

connector

4. Plug the male end of the C-36 to C-36 male/female

printer cable into the printer.

If your serial cable is long enough, you can plug Note:

the SXP-320A/SXP-325A directly into the printer,

without the need for a printer cable.

5. Plug the Power Adapter into an AC source; plug the

Power Adapter cable into the SXP-320A/SXP-325A's

power jack.

Setting the Switches

Baud Rate:

The baud rate is set with DIP Switch segments 1 - 3, as

shown in the table, below

Parity:

Parallel to Serial:

When performing a Parallel to Serial interface conversion:

1. Plug the male end of a 25-pin (male) to C-36 (female)

printer cable into the PC's parallel port

2. Plug the female end of the 25-pin to C-36 male/female

printer cable into the SXP-320A/SXP-325A's Centronics

connector

3. Plug the male end of a 25-pin to 25-pin male/female

serial cable into the SXP-320A/SXP-325A's serial

connector

4. Plug the female end of the 25-pin to 25-pin male/female

serial cable into the printer's serial port

5. Plug the Power Adapter into an AC source; plug the

Power Adapter cable into the SXP-320A/SXP-325A's

power jack.
