P1130A Black Box Serial Parallel Converter

P1130A Black Box Serial Parallel Converter

• Bi‑directional converter: Converts between parallel (DB‑25) and serial (DB‑25) communication formats

• Baud rates: Supports 1 200 – 115 200 bps across common settings (e.g., 9 600, 38.4k)

• Flow control: Both hardware (DTR/RTS) and software (XON/XOFF) supported

• Data formats: 7 or 8 data bits, odd/even parity or no parity, 1 stop bit

• Power: Draws power from DTR/RTS handshake lines or an external 7–18 VDC @ 2 mA power supply

• DIP switch configurable: 8‑position DIP for direction, baud, flow, bits, parity settings

• Buffer: 96‑byte internal buffer

• Size: Approximately 3.8″ × 2.4″ × 0.9″

🛠 Typical Use Cases

• Parallel‑to‑serial: Connects DB‑25 parallel port (from PC/LPT) to a DB‑25 serial device (e.g., printer).

• Serial‑to‑parallel: Opposite direction—serial port sends to parallel printer.

• DIP switches let you control mode (bit 8), flow control (bit 4), and others via a quick hardware config.
