I'm trying to get a 20 year old microcomputer back up again. It requires a serial terminal interface which I no longer have (because I stupidly gave away the VT100 type terminal I used to communicate with it). Rather than buy one that would be expensive and of little future use, I started looking for a more modern solution. Having been working in electronics for many years, I have learned that one can get lucky and everything works okay the first time. Failing that, troubleshooting digital hardware can be difficult and time consuming. As a learning experience with new hardware and to simplify getting the basic RS-232 communication link back up, I purchased an Arduino processor board and an RS-232 "shield" to go with it. The shield simply converts the digital levels from the Arduino to RS-232 levels. These Arduino products are great, very flexible, and relatively cheap. Programming software is free and the language used is more or less "C". Plenty of programming examples are in existence. So, I was able to get the Arduino's RS-232 output going (looping output data) which I first looked at with a scope. Next, I brought up an old tower PC running XP. I started using this computer because it had a DB-9 RS-232 port and a terminal program known as "Hyperterminal". After XP, Hyperterminal has to be purchased separately. Hooking up to the PC and Hyperterminal worked just fine. Next, I wanted to get rid of the tower PC and run things from a small ACER netbook portable. This is where the Trendnet product comes in since the ACER doesn't have a DB-9 port. I was hoping the driver for this device would install automatically but it didn't so I had to use the supplied CD. Since the ACER didn't have an internal CD drive, I hooked up and external one through a USB port and loaded the driver without incident. If you don't have an external drive, I imagine you could use another computer to load and then send the file over your LAN. The next stumbling block was that Hyperterminal was NOT installed on my ACER. Rather than try to figure out why, I looked on line and found another (free) terminal program called RealTerm. Hooking the Trendnet to the Arduino DB-9 and an ACER USB port worked fine. The only thing I noticed, which could be a problem for some, was that no "thumbscrews" were provided on the Trendnet DB-9 end. This end stays mated okay with the DB-9 end on the Arduino, but I don't particularly like to leave DB connectors unsecurred to each other. One could use a short jumper cable, but who needs extra work and cost. Over the years, I have purchased several other Trendnet products and found that they generally did what was advertised and were of good quality for the price.

Works great with dexdrive on Windows 10
I bought this adapter for my dexdrive and it works great on windows 10, running the updated dexdrive software. I didn’t even have to use the install disk that comes with the cable as windows 10 automatically installed the proper drivers. For the price you can’t go wrong with this cable. Its a must have if you need to connect an older device to a newer computer!
