I used them to put two USB RS232 adapters together back-to-back for testing purposes. My only wish was that both sides of these adapters had female screw posts to allow my RS232 adapters to both screw into these null modem adapters. They are perfect for me otherwise. ### ⭐⭐⭐⭐⭐ Solid product *by on Reviewed in the United States January 27, 2021* Have used dozens of these on marine vessels in moist and corrosive environments with a lot of vibration. They hold up well. The narrow design is great. Other null modems are an inch long and take up more space. ## Frequently Bought Together - Arnorin DB9 Null Modem Adapter Male to Male Slimline Data Transfer Serial Port Adapter 2 Pack - Arnorin DB9 Null Modem Female to Female Slimline Data Transfer Serial Port Adapter 2 Pack - DB9 null modem male to female slimline data transfer serial port adapter 2 Pack --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/90565112-db9-null-modem-adapter-male-to-male-slimline-data-transfer](https://www.desertcart.be/products/90565112-db9-null-modem-adapter-male-to-male-slimline-data-transfer) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-10-30*
