PL2303 USB to RS485 Converter

This compact USB 2.0 to RS485/RS422 converter uses the proven PL2303 chip and features a DB9 male connector, housed in durable plastic + metal construction. Cable length is approx. 1.8 m. Operating temperature: 0–70°C (32–158°F); storage: –20–85°C (–4–185°F); humidity tolerance: 5–95% RH. Package contains 1 × adapter cable, 1 × 6-pin terminal board, and 1 × driver CD (random colour, no selection possible). It bridges modern USB hosts (PCs, laptops, embedded systems) with industrial RS485/RS422 peripherals such as access control readers, surveillance DVRs, PLCs, digital multimeters, and environmental sensors. Fully compliant with USB 2.0 (backward-compatible with USB 1.1), it achieves up to 5 Mbps serial throughput and supports standard Windows (98/SE/2000/XP) and macOS (v8.6+) platforms. Engineered for reliability in demanding applications, the adapter supports RS485’s differential signalling for noise rejection and multi-point networking — allowing up to 32 nodes on a single bus. Its integrated terminal block simplifies field wiring, while the hot-swap capability ensures minimal downtime during device rotation or firmware updates.
