Specifications:
The Telebyte, Inc. Model 265 is an
optically isolated RS-232 to RS-422 interface converter. It provides total electrical isolation, handles full-duplex data rates up to 19.2 KBPS over distances up to 2 miles, and protects connected equipment from high-voltage surges exceeding 10 kilovolts in noisy industrial environments.
Core Specifications
- Conversion: Full-duplex signal conversion between RS-232 and RS-422 standards.
- Isolation: Complete optical isolation preventing ground loop currents between separate systems.
- Surge Protection: Withstands electrical spikes and surges over 10 kV on the RS-422 lines.
- Distance: Supports communication links up to 2 miles (approx. 4,000 to 10,000+ feet depending on wire gauge).
- Power: RS-232 side steals power from control/data lines (RTS, CTS, DSR, DCD, DTR, or TD), while the RS-422 side uses an included wall-mounted external power supply.
- Indicators: LED lights display real-time Transmit Data (TD) and Receive Data (RD) flow
