Had to return it and purchase a different product. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.id/products/20868920-io-crest-4-port-rs-232-serial-pcie-2-0](https://www.desertcart.id/products/20868920-io-crest-4-port-rs-232-serial-pcie-2-0) --- *Product available on Desertcart Indonesia* *Store origin: ID* *Last updated: 2026-05-13*
