Isn't this actually a "DE9" RS232 adapter? Wikipedia show "DB" plugs as much wider -- for holding 25 pins.

From Wikipedia:"It is now common to see DE-9 connectors sold as DB-9 connectors. DB-9 nearly always refers to a 9-pin connector with an E size shell."So they're basically synonymous now, although it looks like you are correct that DB is the wrong definition for these types of plugs.

This is a DB-9 connector. RS-232 can have either a DB-25 or DB-9 connector. The DB-25 standard is older. Most new equipment uses the 9-pin version. Here is a link that provides a nice explanation between the two connector types:http://www.lammertbies.nl/comm/cable/RS-232.html

It is for a standard 9-pin DB9 RS-232 serial connector according to the literature provided. It does receive a 9-pin plug, just couldn't get it to recognize the device that I was trying to connect.

Technically you are correct. The 2nd letter denotes how many pins are used. The name just stuck from days of old.

it wont help at all, this was my worst and most useless adapter i ever tried to figure out...i usually only work with 1/4 inch connections...this little adapter is great for RCA cables but amazon should describe what their selling with some detail cause they confused the hell out of me...nothing that YELP cant handle..

Technically it should be possible to use this device on a four wire full duplex rs485 bus. All the signals are available and the ftdi chip can certainly work full duplex. Only I haven't used it with rs485 yet. On rs422 it works great.

No. I think you have the wrong product. This is for controlling RS-232 devices over IP. It's a serial connector. You are looking for a USB Print Server. Start you search with that term and it should lead you in the right direction. Good luck!

Arthur I used to use this for an IBM T23 Think Tank. Was good for USB connections 1.0 and I think raised connectivity to 2.0. I don't recall the plug or power issues but remember it worked well. Sorry I can't give you the technical info at this time. Have simply forgot how it worked. SamN

This device is used to connect 9pin RS-232 serial devices to newer computers that do not have a legacy serial port. It will not work with 15pin VGA connections.

I purchased one and the connector has 20-pins. Look at the photo. How could two equal rows of 10-pins be an odd number?

I would have to look back in my notes. The 3 pin connector is for 1. a +5vdc source, 2. for a logic ground, and 3 for the output signal, not necessarily in that order. If you really need the info, leave me a message and I will research it again.

Yes Fedora23 use this adapter New Premium External Power Supply 5.0v 2.0A (2000mA) AC/DC Adapter for USB HUB. hope this help it is what I use and I have a red 7 port hub as well

No, this is a adapter to convert a serial DE-9 (9 pin) comm port to a DB25 (26 pin) comm port. You have to have a SCSI card installed which will have the proper ports on it in order to use SCSI devices.

It doesn't work at the logic voltage level that the technical rs232 spec requires. But the communications are serial protocol. You would need a logic level converter to use this with rs232.

In the Centronics side, there are 36 pins but in a smaller connector. (I saw Kathleen's answer, 25 pin is on the PC side, the older PCs with a parallel port.)

They are not interchangeable. Only one pin count will fit the slot. It will be either 184 or 200.

I apologize, I don't know what an express port slot is. It looks like there are a lot of ports on it for various purposes.

It has female pins, so you'll need some adapter. Personally I adapt it to the USB on my laptop with a Dynex DX-UBDB9. But if you are going to the rs232 a straight m/f adapter would work.

it is .146 diameter, and the adapter is .5v ac output on my 7 port hub. shouldn't matter.

Don't know, there are 5 pins in the connector and not all manufacturers wire those pins (only 2 are needed) the same. Best route to get your question answered would be to call the vendor directly to field your question. Problems? Call 706.935.0065 and ask for Angela - let 'er know Nick sent you:)
