Gotallofthem “Speed Demon” – June 5, 2015

I have a home lab that I have built for my Networking Studies, and I needed a way to access each switch/router without having to constantly plug and unplug my console cable each time I needed to make changes (which is really annoying if you know what I am referring to). My choice was between buying an access server which would have cost me a lot more, or purchasing this item. I must say this has done the job perfectly, I can control 4 different units, with one connection, and not having to constantly get up out of my seat. If you have a home lab, or you need a way to access your switches and routers at the same time, at home/work, this will work great for you.

JohnG – January 13, 2015

Most of the inexpensive serial to RS-232 converters have been bricked (made unusable) by an update to windows 7 and 8 by Prolific(FTDI) in order to punish counterfeiters of their chips and I can understand that. However, it leaves people like me with
devices that are worthless! I have several converters from GearMo that have seemed to survive. Don’t know if it is the drivers they send or if they are using legitimate FTDI chips. The bottom line is that so far they work fine and are well built. I know for sure that the little blue converters and a lot of cheep ARDUINO boards suffer problems from the update. There is a somewhat involved workaround to fix the problem but I don’t know if it is worth it. Could be that another update from Prolific could render the fake ones inoperable again. Bottom line….. Pay a little more, buy from Amazon and one way or another your problems will be taken care of.

Nothing comes close to the value. I’ve connected this to a raspberry pi in order to use it as a terminal server for my cisco lab equipment. I will be buying another one of these in the near future. I love that the connectors are numbered and that the cables are of a good length
