Questionb about the MINI USB to RS485 converter. Will this converter work to connect to an RS485 full duplex device

RS-485 is half duplex (2 wires). For full duplex, you need RS-422 -- which this does support, but I've not used it.

Yes it does. We are using it on full duplex networks. This is a great device and has plug and played on all of our laptops.
282542
The short answer is 'no' - it will do full duplex on RS-422, but not RS-485.

I think ;that you can find the answer to this question in the datasheet for this device - located in the images section. It shows use in a RS-422 full duplex application which should also be applicable to a RS-485 full duplex application.

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.

You might be able to use a USB - RS485 adaptor, depending on the software that controls the camera and what it expects to see as a RS485 port

I don't think so..maybe if you had the converter. I'm not 100% it would work.

No I do not think it will work it needs a Windows or Mac Driver to work. On Amazon just search ASIN B00GX71GNO I use the second item pictured and works good. Or you can try the 8th one pictured I think that will work. It will have a much better chance or working over the Mini USB.

I think that the device is normally in the RX RS485 mode and passes RS485 buss data to the Virtual Com Port created by the USB.When the TX buffer is filled from the USB side, it switches to TX and then reverts to RX

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!

I should be connected into usb port and it is as simple as plug and playyou can contact me on laxmikant.btech@gmail.com

Yes, It works fine. I installed a rs232 driver to use with USB port and It works excellent. I am using EasyGPS program in Win and LoadMyTracks program in Mac.

I had to buy a separate mini USB mini adapter, I think I got it from eBay. So technically, it didn't work as it was sold. Here's the adapter I bought-http://www.ebay.com/itm/2-Pack-Lot-USB-A-Female-to-Mini-USB-B-5-Pin-Male-Adapter-AUA2-MN51-2PK-/270977749326?pt=US_USB_Cables_Hubs_Adapters&hash;=item3f1788514e

I don't know. It didn't work in either of my applications (an RTL-SDR TV/radio receiver, and a USB-to-RS232-serial adapter). The problem appeared to be too many lost frames over the USB interface, the drivers would get confused and "give up".

Its pretty good in terms of transmission. I checked on modscan to see whether my loop is transmitting the datas or not. It really helped me to find that on RS485 communication. Speed was not my concern but the data being transmitted or received was checked.

Hello Gabriel, wow: I have the same issue: a MacMini (MA206LL/A) which has sporadically non-functioning USB ports. But the firewire 400 port works fine, so I figured there had to be a Firewire-->USB converter. But I haven't been able to find any well-reviewed adapters or converters; most products (e.g. direct from China for 40 cents) seem to just offer physical connections but don't modulate the voltages or signals.Anyone else have any ideas, since this Belkin doesn't cut it?

Probably yes. With the driver installed, it emulates a COM port. I use mine to program a battery management system which requires RS232. Works fine.

These devices (if you have the 485 version NOT the 232 version) do indeed handle 2-wire RS-485, which is what you probably mean (something like "Pelco-D?) You will need the right software and device drivers. We use these devices in the SIA open-osdp project on Linux. Look for open source PTZ software on Sourceforge and like places.

Hi there, I found out that all these cables are useless! Only the converter device worked for me! Of course I have not checked them with every equipments, but I wasted money on five or six different cables, and none of them actually worked for any degree of satisfaction! And I was too lasy to return them, mainly because I lost the track of them when I bought them and what was the name of the cable!

I use mine with a powered USB hub. It has to be a powered hub, not just one that clones the port. This adapter draws much more power then a standard usb port supplies. Experiment with the power TX out put slider in the alfa utility. Reduce the power output until the signal increases. Multiply the % output on the slider x 2000 and that's how much your usb port is putting out max in Milliwatts(mw). Mine worked much better after putting it on the powered USB hub.

Not sure, but I think that they can give you a small converter box (by Cisco) that should do the trick. Good luck.
