Simply plug these adapters onto the end of a cable and you're done ! Review: Works perfectly! - It does its job. Definitely a quality item. Review: Non-standard pinning. DCD is tied to DSR on both ends (1+6) - This review is for the gold plated version. It has non-standard pinning. Pins 1 & 6 are tied together on both ends. This ties DCD to DSR on both ends. There is no reason to do this, even on a full handshake null modem connection. TXD and RXD should be cross connected (2-3 & 3-2), DSR and DTR should be cross connected (4-6 & 6-4), CTS & RTS should be cross connected (7-8 & 8-7), and ground (5-5). There is no reason to tie DCD to DSR. This caused them not to work with my application. ## Features - Converts standard, straight wired cables to null modem wiring - Null modem configuration with pin 9 open. - Slimline design reduces leverage strain on computer ports - UL grade 94V-0 connector insulator satisfies flammability requirements - Screws are removable and reversible ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0772VPX95 | | Brand | Arnorin | | Color | Gold plate 2 pack | | Colour | Gold plate 2 pack | | Compatible Devices | Modem | | Compatible devices | Modem | | Connector Type | DB9 | | Connector type | DB9 | | Customer Reviews | 3.6 out of 5 stars 12 Reviews | | Finish | Gold | | Finish type | Gold | | Input Voltage | 94 Volts | | Item Dimensions | 13 x 18 x 33 millimeters | | Item dimensions L x W x H | 13 x 18 x 33 millimeters | | Manufacturer | KINGDEE INC | | Mfr Part Number | KAD9D90001-S-G-2 | | Model Number | KAD9D90001-S-G-2 | | Number of Ports | 4 | | Package Quantity | 1 | | Power Plug Type | No Plug | | UPC | 661083103738 | | Unit Count | 2 Count | | Warranty Type | Limited | ## Product Details - **Brand:** Arnorin - **Colour:** Gold plate 2 pack - **Compatible devices:** Modem - **Connector type:** DB9 - **Item dimensions L x W x H:** 13 x 18 x 33 millimeters ## Images ![JIACHEN DB9 null modem adapter male to female slimline data transfer serial port adapter gold plated 2 Pack - Image 1](https://m.media-amazon.com/images/I/7189aEx7+WL.jpg) ![JIACHEN DB9 null modem adapter male to female slimline data transfer serial port adapter gold plated 2 Pack - Image 2](https://m.media-amazon.com/images/I/71tOjVREAFL.jpg) ![JIACHEN DB9 null modem adapter male to female slimline data transfer serial port adapter gold plated 2 Pack - Image 3](https://m.media-amazon.com/images/I/61AaM+X4NdL.jpg) ![JIACHEN DB9 null modem adapter male to female slimline data transfer serial port adapter gold plated 2 Pack - Image 4](https://m.media-amazon.com/images/I/71lNl4YlotL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works perfectly! *by E***A on 20 April 2026* It does its job.
