This manual introduces the features, installation, default configuration, DIP switch settings, cabling, operation, troubleshooting, specifications (RS-232C interface specification, Centronics interface specification, Centronics interface timing chart, preventing radio and TV interference) of SXP-320A/SXP-325A bidirectional serial/parallel converters.
The SXP-320A and SXP-325A are bidirectional serial/parallel converters that allow RS‑232 and Centronics devices to communicate with each other. The SXP-325A includes a 512 KB buffer for printer data, while the SXP-320A operates without memory. Both units support baud rates from 1200 to 115200 bps and provide hardware and XON/XOFF handshaking.
This manual covers an overview of the converters, features, installation steps, default DIP‑switch configuration, cabling diagrams, operation guidelines, troubleshooting procedures, detailed specifications, and FCC interference warnings.
| Serial baud rate | 1200‑115200 bps |
|---|---|
| Parallel interface speed (SXP-320A) | 11.52 KB/sec |
| Memory size (SXP-325A) | 512 KB |
| Power consumption | AC 9 V 150 mA (max) |
| Cable distance | Up to 9 m (30') |
Set the baud rate using DIP Switch segments 1‑3 as shown in the DIP‑switch table.
The SXP-325A includes a 512 KB buffer for printer data.
The unit requires a 9 V AC power adapter rated at 200 mA.
