3.0 out of 5 starsSo close yet so far
By Amazon Customer on July 24, 2006
Classic design goof up.

This serial adapter has a DB9 male connector in the DTE pinout.

I purchased this adapter to plug into the console ports of various computers and network switches so it should've been a DB9 female connector in the DCE pinout. Clearly, they realized this so they provide a female to female null modem adapter (most null modem adapters are male to female).

Unfortunately they left pin 9 unconnected as would be the case in most null modem cables and most null modems, although this is normally a reasonable precaution, this device derives it's power from pin 9 which being unconnected, does not work very well. To account for this oversight, they've provided an external power adapter with an european to US plug adapter, not a very portable solution, nor is it very wireless solution.

The product is still usable if you build your own female to female null modem adapter with pin 9 connected through.

1.0 out of 5 starsJunk
By RobertF on November 15, 2006
I purchased this to connect to a weather station. Real simple handshaking, no special drivers needed. Works by dumb polling.

However, it doesn't work. I can connect via hyper terminal through a port and it does work, but I need it to act as a slave.

I sent IOGear a rather detailed explaination of what I'm doing, and what I've tried - what I got back was a one line sentence telling me to try something I had already told them that I had tried. I emailed them back a second time and I've yet to get a response. It's now been 3 months.

I give it a "1" rating because it didn't do as it claimed it should, and IOGears technical support was completely lacking.

4.0 out of 5 starsNice Bluetooth Adapter
By John P. on March 18, 2010
Verified Purchase
I used this item to convert my GPS output from serial to Bluetooth. This product worked very nicely. I can get excellent range from the adapter on my GPS to a Bluetooth laptop or pda. My only complaint is that I cannot figure out how to establish two way communications. I can receive data from the GPS no problem. If I want to send data to the GPS via Bluetooth in order to change the type of data stream output from the GPS I have not been able to do this. It appears that Bluetooth serial profile creates 2 COM ports. Example COM6 is Data from the Adapter to the PC and COM7 is Data from the PC to the Adapter. All of my programs use only one COM port for bi directional communications. So all I can achieve is a one way street. There may be another way to do this but this is my experience. I also had to make a power adapter for the Bluetooth device as I couldn't use the supplied AC adapter for my project. I used an old car Cell phone charger to convert 12V to 5V for the adapter on Pin 9 for Power.

3.0 out of 5 starsIt requires AC Power to work.
By Amazon Customer on July 8, 2010
One of the claims is it frees all the cables. It doesn't. IT REQUIRES AC POWER TO WORK. Normally all the portable devices that I have seen come with a battery. But this device doesn't and you need to connect the adapter or tweak the hardware to supply power from your board. So, basically you are eliminating RS232 cable and replacing it with a power cable.
I tried this with Windows 7 and it showing up as two com ports. I can send data but cannot receive data from device. I tried to contact customer support and they charge 100 dollars to debug my problem.

Update:
Thanks to the forums, it looks like the device is doing hardware handshake and there is no way to disable it :(.
If you want to connect to a system with no RTS and CTS pins, then just connect another serial cable (this will make this null cable) and short RTS and CTS lines.

4.0 out of 5 starsWorked for me
By Amazon Customer on January 12, 2008
Verified Purchase
I was pretty apprehensive to purchase this item based on the other reviews, but I was also pretty stuck. I have a weather station that has an RS232 port but I didn't want to have to tether it to my PC in the study with a serial cable. From other bluetooth experiences, I knew that bluetooth had a serial capability, so I thought I'd give it a try.

Getting it to all work was a challenge, I'll admit. I started with a wired connection to the weather station and made sure everything was fine. I added a bluetooth adapter to the PC and made sure other things could connect to it (bluetooth seems to be very finicky that way). I then disconnected the serial wire and hooked up the bluetooth adapter to the weather station. The joining seemed to work ok (XP box) and all was well. Unfortunately, the bluetooth serial adapter comes across on COM11 and the software I was using for the weather station only supported up to COM4. I found some trialware com port redirection software which allowed me to redirect COM11 to COM1 and voila...it all worked.

One very annyoing problem: The serial bluetooth connection seems to be session specific...if another user logs-in to my PC (or if I remote into the box) the serial connection is lost. I'm not sure if that's a problem with this device, my bluetooth adapter, my adapter's software, or how XP ties it all together, but it is annoying. The PC in the study is a common use machine for our family and it was nice for us to each have our own accounts (separate desktops, bookmarks, etc). I've tried reasonably hard to get around that, with no success. One funny note...the bluetooth mouse that I used to vaidate my adapter is not session specific...it seems to run in a machine context. Too bad the serial adapter doesn't.Read more ›
