QUATECH ThinkQ QSE-100D-BA 4 Port RS-232 Serial Server (CHEAP!)

I received my power supplies today, and I'm not happy. Looks like they do just relabel them. I received 4 of them, 2 were 2A, 2 were 1A, same model #, same exact look.

Not sure if I trust them now.

thanks Dan (Electron),
that's good to know that it is natively supporting UDP packets as opposed to TCP;
there are some interesting advantages to UDP as far as packet loss is concerned and perhaps that is why the torrent applications use this protocol instead for data transfer.
is v1.42 the latest drivers for WindowsXP?

Look at the 2 amp one, the sticker looks crooked compared to the 1A one...

By looking at the sizes of these I would not think they were 2 amp.... you could plug one into the unit and see how warm it gets... I doubt that these units draw anywhere near 2 amps.... also if you can check the voltage while it is powering the unit to see if if drops it below 5V might let you know how much of a load it is placing on the walwart.
Anyone here have any knowledge on how to set one of these up Remotely?
I have two Quatech so far, I configured the second one to my other HomeSeer at my remote house and then took the PC back to Atlanta. Now I am trying to connect without any luck.
I am actually back at the remote house and connecting to my HomeSeer box via remotly (va RADMIN) and I can not connect to the Quatech. I had hoped this would be much easier. I had mine up and working running X10 and Z-Wave without a hitch. It was great. These things are great!
I configured my PC with my 4 Port Quatech (e.g. setting up the QSE-100 Four-Port RS-232 Serial Device Server for Multi-port adapters), and took my 4 Port Quatech to my other house. I configured the Router to forward ports 5000-5003 at the remote location on 192.168.1.18 on the router. In Atlanta, I can ping the Quatech, but when I go to the SDS configuration screen and change the TCP/IP configuration parameters with the correct external IP address, Subnet and Default Gateway addresses, I am presented with an error code: "Another network device has been detected, via a simple ping test, at the requested IP Address for the SDS. Check with your network administrator to have a unique IP address assigned for your SDS. Process Aborted!" (I have verified all the addresses many times over, even calling support to be sure).
The 4 Port Quatech is on a unique IP address behind the Router per above with no conflicts, plus I changed it to two other addresses and received the same error code. I thought when I placed the EXTERNAL IP address of my MODEM (of my remote house), into the PC SDS configuration screen in Atlanta, it would find the Quatech via the forwarded ports.
- What am I missing in configuring the 4 Port Quatech for Remote Use? Both of my Routers support VPN Tunnels, (I saw a post that maybe Michael McSharry might know how to set one up). From another post I received it did not appear I needed to setup a VPN to make it work that another person was doing but I have not had any replies to my post over on HomeSeer yet. - Cheers Gary

I was thinking the same thing: surely these devices do not draw 2amps. But when I thought about 5v * 2A = 10watts. . . That does not sound unreasonable for one of these. . .
They really are small for being a real 2A power supply. I know someone in the chat room had his working with a 1A power supply, so they don't use 2A out of the box, but I assume once you start connecting 4 serial devices, and some more processing takes place, it will get above 1A.
Welcome to CT Gary!
My apologies, but I am having trouble 'following' this post. That said, the QSE-100 should not have an external IP address. Port forwarding will take care of translating requests to the external IP back to the internal IP of the QSE-100. Pre-configure the remote QSE-100 with the correct LAN IP address (initial configuration requires the QSE to be on the same physical network segment as the computer you are using), then move the QSE-100 to the remote location. I'm not sure if simply forwarding the serial ports is enough to make the remote QSE visible to the SDS software (I assume there is also a port for 'control').
I have accessed my QSE remotely, using a VPN connection, and it works without any problems. I also STRONGLY recommend that you create a VPN tunnel between the 2 remote sites, since using simple port forwarding will expose your hardware directly to the internet, and will make things more complicated anyways.
Well, to me the bottom line is that the HK 2 amp power supplies work with the QSE-100, do not run excessively hot (my router's power supply runs noticably hotter), and are relatively inexpensive.
Honestly I think all three of their PS with the same model number are probably rated for 2amps, but they do rebadge it for lower ratings rather than paying to develop and produce lower rated devices. Seems like good economics to me.

Ya, dunno what to tell ya. I was lucky all mine came and are 2A, but heck, they could all just be LABELLED 2A.
You can complain, but if he requests you send the bad one back, then it probably won't be worth it. You can make a claim in paypal, assuming you paid that way, but I think they also require that you make an effort to "work it out", which probably means shipping the bad one back. Or, you can call your credit card and file a claim, and if they're anything like mine was, they'll just reverse the charges without any other info. (came in real handy when I got a dinged up power generator and the seller wasn't responding at all).
Or just shrug it off and find another one online. *shrug* Either way, sucks.
I'm not concerned about the small size of these things. The dlink power supply I scrounged up to test the QSE's isn't any bigger than these HK power supplies, and it's 2A, and made by an apparently reputable company.
