The 5000N\/5000NV family provides a standard RS-232 data interface that can be driven asynchronously from 1200 to 19,200 bps, with an optional 38,400 bps, and automatically autobauds to the DTE speed for plug‑and‑play operation without manual speed matching. It transmits data and receives in half‑duplex mode, and, unlike packet‑based networks, remains transparent to the user’s protocol, requiring no error correction or packetization within the radio modem. This makes it ideal for remote device communication where a direct RS‑232 link is desired, effectively replacing a long serial cable with a wireless connection. The module is powered by 12 VDC, suited for industrial installations, and is designed for easy integration with standard equipment that uses RS‑232 interfaces. In the Gina line, models like 5000N offer data‑only transmission, while 5000NV adds an optional voice handset; later generations expand into 2.4 GHz variants for different ISM band operations. Whether upgrading legacy equipment, creating remote sensor links, or enabling remote monitoring, the Gina 5000N family delivers a rugged spread‑spectrum interface that preserves serial data integrity across a wireless link.\u003c\/p\u003e\u003c\/div\u003e","brand":"Spectrum","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46259704594666,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-014.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/industrial-gina-500n-spread-spectrum-radio-modem","provider":"GTG Hardware","version":"1.0","type":"link"}
