Compatible with Linux, MacOS 8, MacOS 9, MacOS X, Windows XP, Windows Vista and Windows 7. Also, works with 64bit versions of the OSes listed that support 64bit. It worked in Linux with 2.6 to 3.x kernels and Windows 7 without the need to install drivers. Windows XP was able to download the drivers. Drivers are provided on the included CD and newer drivers are on their site. The device is small and works well. This device is awesome, but I have two complaints. 1) The ports are close together so it is hard to use some connectors next to each other. 2) In Linux once a port was accessed, if I unplugged the device and connected it again, the ports that have been accessed can no longer be accessed. Ports that were not accessed previously can be accessed until the next unplug and replug. A restart fixes the issue. I imagine this is more related to the driver that my Linux OS was using and/or there may be a method that can allow access again without a restart that I have not found yet. Review: Pro grade - This is not your cheap, plastic adapter. This is well built of metal and shielded with a good chip set. For that you have a fairly large piece of equipment that is larger and heavier than most other similar products. It works as advertised and is RF proof for use in radio applications. I had no problems with my Windows 7 machine. Drivers worked with no problem and 4 comm ports were created in the OS. You can use external DC power, but it will take power from the USB buss easily enough. ## Features - Supports 4 serial ports with data rates from 75 bps to 921.6Kbps - Multiple module support through the USB interface - USB Port Fully compatible with USB1.0 and USB1.1; Forward compatible with USB 2.0 - Supports 3-wire RS232 Signals (TXD, RXD, GND) - Rigid Metal Case for surface mounting and critical applications ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B004ET6R50 | | Best Sellers Rank | #937 in Serial Adapters | | Brand | SerialGear | | Color | Black | | Compatible Devices | Devices with RS-232 DB9 female serial ports such as printers, modems, CNS machines, PLCs, radios, etc. Compatible Devices Devices with RS-232 DB9 female serial ports such as printers, modems, CNS machines, PLCs, radios, etc. See more | | Connector Type | DB9, USB Type B | | Customer Reviews | 5.0 out of 5 stars 7 Reviews | | Finish | Matte | | Finish Type | Matte | | Input Voltage | 5 Volts (DC) | | Item Weight | 16 ounces | | Manufacturer | SERIALGEAR | | Mfr Part Number | USBG-BAY4 | | Model Number | USBG-BAY4 | | Number of Items | 1 | | Number of Ports | 4 | | Package Quantity | 1 | | Power Plug Type | No Plug | | Smart Home Compatibility | Not Smart Home Compatible | | Specific Uses For Product | Connecting 4 legacy serial devices to modern host systems | | UPC | 729440626976 | | Unit Count | 1 Count | | Warranty Description | 1 Year | ## Product Details - **Brand:** SerialGear - **Color:** Black - **Connector Type:** DB9, USB Type B - **Specific Uses For Product:** Connecting 4 legacy serial devices to modern host systems ## Images ![USB to Serial 4-Port DB-9 RS-232 Adapter with FTDI Chipset – Works with Windows 10, 8, 7, XP and Mac OS Systems - Image 1](https://m.media-amazon.com/images/I/51LX2CLHguL.jpg) ![USB to Serial 4-Port DB-9 RS-232 Adapter with FTDI Chipset – Works with Windows 10, 8, 7, XP and Mac OS Systems - Image 2](https://m.media-amazon.com/images/I/61HFp04UgBL.jpg) ![USB to Serial 4-Port DB-9 RS-232 Adapter with FTDI Chipset – Works with Windows 10, 8, 7, XP and Mac OS Systems - Image 3](https://m.media-amazon.com/images/I/61IqW+dfwfL.jpg) ![USB to Serial 4-Port DB-9 RS-232 Adapter with FTDI Chipset – Works with Windows 10, 8, 7, XP and Mac OS Systems - Image 4](https://m.media-amazon.com/images/I/61sE5p6JSpL.jpg) ![USB to Serial 4-Port DB-9 RS-232 Adapter with FTDI Chipset – Works with Windows 10, 8, 7, XP and Mac OS Systems - Image 5](https://m.media-amazon.com/images/I/61RVBJwGtGL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent 4 Port USB to Serial Adapter *by C***M on February 25, 2012* Uses the FTDI 232RL chipset with support for the chipset's full RS232 performance, 300bps to 921.6Kbps.

I use it for amateur radio applications where it is exposed to moderate levels of RF. It is well known that the FTDI chipset is superior to any other for radio control applications. The all metal enclosure properly shields the internal PCB from RF. I would recommend this to anyone needing a multi-port USB to Serial adapter, and especially to those working around RF.
