It is a straight through adapter. Review: NOT a null modem adapter as claimed! Straight pass-thru, useless. - The product is NOT a null modem adapter as claimed, but an ordinary straight-through adapter — exactly the opposite of the product description! A null modem adapter converts a standard serial cable into a null modem cable, enabling two devices to communicate directly by crossing the transmit and receive data lines. I’ve attached a diagram showing correct null modem connections. The Q&A for the product listed says: Q. Does this cross send and receive lines? A. Yes, this adapter is a null modem adapter, which means it crosses the send and receive lines for proper data transfer. But testing with a multimeter shows none of the pins cross over — they are wired straight through. The product is thus useless for its intended purpose. ## Features - Multiple Adapter Combinations: This 3-pack set includes DB9 Female to Female, Female to Male, and Male to Male adapters, providing flexible connection options to meet various device and application needs. - Plug and Play, No Extra Drivers: No need for additional software or drivers—simply plug in the adapter for instant data transfer, making it easy to connect all types of serial devices and saving setup time. - High Durability and Stability: Made with high-quality materials, ensuring wear-resistance and long-lasting stable data transmission for industrial, commercial, and personal use. - Compact Design, Saves Space: Its lightweight, compact design makes it ideal for use in limited spaces, reducing strain on computer ports and saving space. - Wide Compatibility: Compatible with a range of devices, including computers, POS systems, printers, industrial equipment, modems, routers, and more, supporting connections across various industries. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0F1FSLLPK | | Best Sellers Rank | #186 in Serial Adapters | | Brand | LNHCAW | | Compatible Devices | RS232 | | Connector Type | VGA | | Customer Reviews | 3.8 3.8 out of 5 stars (7) | | Item Dimensions | 1 x 1 x 1 inches | | Item Weight | 1 Grams | | Manufacturer | LNHCAW | | Model Number | F-F (2P) | | Number of Items | 2 | | Number of Ports | 1 | | Specific Uses For Product | null modem adapter，db9 gender changer，vga adapter，db9 connector | | UPC | 767791851739 | | Warranty Description | 2 | ## Product Details - **Brand:** LNHCAW - **Compatible Devices:** RS232 - **Connector Type:** VGA - **Item dimensions L x W x H:** 1 x 1 x 1 inches - **Specific Uses For Product:** null modem adapter，db9 gender changer，vga adapter，db9 connector ## Images ![db9 Connector Null Modem Adapter，9-Pin Serial vga Adapter RS232 db9 Gender Changer,for Computer and Industrial Device Data Transfer(F-F (2P)) - Image 1](https://m.media-amazon.com/images/I/61OSqlifkNL.jpg) ![db9 Connector Null Modem Adapter，9-Pin Serial vga Adapter RS232 db9 Gender Changer,for Computer and Industrial Device Data Transfer(F-F (2P)) - Image 2](https://m.media-amazon.com/images/I/71fonpJQIqL.jpg) ![db9 Connector Null Modem Adapter，9-Pin Serial vga Adapter RS232 db9 Gender Changer,for Computer and Industrial Device Data Transfer(F-F (2P)) - Image 3](https://m.media-amazon.com/images/I/71ynFJ2TPQL.jpg) ![db9 Connector Null Modem Adapter，9-Pin Serial vga Adapter RS232 db9 Gender Changer,for Computer and Industrial Device Data Transfer(F-F (2P)) - Image 4](https://m.media-amazon.com/images/I/61wFVEqkY9L.jpg) ![db9 Connector Null Modem Adapter，9-Pin Serial vga Adapter RS232 db9 Gender Changer,for Computer and Industrial Device Data Transfer(F-F (2P)) - Image 5](https://m.media-amazon.com/images/I/71EHNz94L3L.jpg) ## Available Options This product comes in different **Model** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ It is not a null modem adapter. *by C***N on January 31, 2026* This is not a null modem adapter.

I got these null modem adapters so that I can still use those older devices with an USB to RS-232 interface cable. While not something I encounter every day, these handy devices allow me to continue using my older peripherals and save me the cost of replacing them. something I appreciate. They mate perfectly with other DB9 connectors and I'm pleased with this 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.tn/products/806728627-db9-connector-null-modem-adapter-9-pin-serial-vga-adapter](https://www.desertcart.tn/products/806728627-db9-connector-null-modem-adapter-9-pin-serial-vga-adapter) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-05*
