I recently purchased two Gearmo 4 Port USB to Serial RS232 Adapters to set up a console server for managing my Cisco network lab, and I must say, I'm absolutely thrilled with their performance! These adapters are connected to a single Raspberry Pi 4, and the setup was a breeze. The installation process was straightforward, and I encountered no issues getting them up and running.What impresses me the most is the seamless integration and ease of use. The adapters are highly reliable, providing consistent and fast data transfers, which is crucial when managing a network lab. I've experienced zero lag or connectivity issues, making my lab management tasks significantly more efficient.The build quality is excellent, and the adapters are compact enough not to clutter my workspace. They've proven to be an invaluable addition to my setup, and I couldn't be happier with how well they've met my needs. If you're in the market for a reliable and high-performing USB to Serial adapter, look no further than the Gearmo 4 Port model. It's a game-changer!

This USB to serial port adapter has 4 separate serial cables that connect to a single USB 2.0 plug.Each of the 4 serial cable ends is slightly more than 3 feet long. The USB cable end is one foot long. Total end-to-end length is a little bit more than 4 feet long.Each serial cable is labeled "1", "2", "3", or "4" which makes it easy to track your connections. The connections always retain the same com port, so you won't need to reconfigure you software after restarting you computer.The adapter has 3 separate LEDs: red = power, green = TX, yellow = RX.The adapter comes with a CD-ROM that contains USB 1.1 and USB 2.0 drivers for many operating systems including Linux, Mac, Windows, and more. The release notes on the CD-ROM mention that newer drivers can be found at [...]No paper instruction manual is included which might cause inexperienced computer users to have moderate difficulty with the setup. Experienced users will find the setup straight forward and simple.Installation on Windows 7 was easy for me. I found the appropriate installer on the CD-ROM. I had to right-click the installer and select run-as-administrator. The first time I plugged the adapter in it took several minutes for the device to be detected, so be patient. Subsequent detections are fast.All 4 serial adapters can be used simultaneously.Overall I am satisfied with the quality of this device.

The USB "jungle" under my desk was becoming a nightmare & I was quickly running out of ports on my USB hub to connect my ham radio equipment to, so I went looking for a good multi-port USB~RS-232 adaptor. Between my 2 main ham transceivers, the packet TNC and the internal TNC I needed 4 RS-232 ports that did RTS/CTS handshake correctly (Kenwood radios are kinda picky in this regard {especially the TM-D710A in EchoLink sysop mode}, as is my TNC). I had been told by numerous fellow hams that USB~RS-232 adaptors that used the FTDI ICs where the only way to go, so I limited my search to these. I saw this item on Amazon & read a review from a fellow ham that had dealt with this same issue, and he praised this unit highly, so I decided to purchase it.I'm VERY pleased with the results. I've hooked up the adaptor to my Toshiba laptop PC (my "shack computer") and to the Kenwoods and everything works just like it is supposed to. There where no issues with the adaptor operating correctly with the radios running full power output (100W on the HF bands & 50W on 2M/70CM) - no "glitches" at all. One thing that had concerned me was possible interaction between the 4 ports when 2 or 3 of them are active (actually passing data) at the same time, which is the situation when running packet. However, no such interaction had been observed.I would HIGHLY recommend this USB~RS-232 adaptor to any ham that is running multiple radios and/or aux. items like a TNC that wants reliable data transfer when you've got a bunch of RF floating around the shack on multiple bands. Gearmo makes a fine product in this item & I WILL personally recommend it to my ham friends.NOTE: I would recommend that anyone that uses this product go to FTDI's web site & download the ComPort Reassign utility - it makes Com Port assignment of the ports on this device much easier than using Device Manager in Windows.

In short, the GearMo 4-port serial adapter ROCKS!I am a professional network engineer and often need to connect to serial console ports on routers, switches, firewalls and more. An RS232 serial connection is pretty much the industry standard for a local console connection to these devices. Since it's common for me to be working on several devices at once -- often trying to make coordinated changes on 2 or 4 devices that must be executed with relatively precise timing -- this product seemed like a better option than moving my console cable back and forth between devices.The 36" cables are a bit bulky when coiled up but the spare length for connections is great when working in a data center rack. The FTDI chipset retains its COM port assignment on Windows after reboots and regardless of which USB port the adapter is connected to -- an enormous improvement over the PL2303 chipset which always changes its COM port assignment. Each RS232 port is embossed with a number (1-4) that indicates which port it is. I mapped these to COM11-14 on my system so I could make an easy mental association with the COM port to the physical connector.This item also works reliably in Mac and Linux OSes. I've been strongly considering building a battery-powered RaspberryPi terminal server with one or two of these to provide an easy-to-access WiFi-connected terminal server.
