Dear fellow ICS people... Apologies... almost "off topic", and very newbie (to TCP/IP), but....
I have a nice little device from PCSensors, their TEMPerLAN. It appears to be great engineering, but, out of China, the English of the software interface is a lot better than my Chinese, but still a little unclear. Has anyone already worked with this? (A lot to hope for, but you never know!) With software supplied with the device, from a Windows PC connected to the same LAN as the TEMPerLAN, I can "send a command" to it. If the command is BB 82, I get back a short string of ASCII with some data from the device. (Temperatures seen by some attached sensors, but that isn't really central to my question!) So, somehow, their software (it would seem!) is able to send something to the device. The software is first "connected" (maybe not in the TCP/IP sense) to the device by the device's IP address. (192.168....) And then the device sends something out, which is received by the monitoring software. On those slender indications, I certainly don't expect anyone to be able to tell me "You just do (this) to duplicate what the software is doing".... but if anyone has guesses as to the sort of thing that is going on, guesses which could narrow my Google searching, I would be very grateful. And no, sorry to say, if the device is at 192.168.0.241, as it is, putting none of the following into the FireFox address bar work. I get "can't connect". (I've tried the 16000 port in the device's reported configuration... not in a relevant part, as far as I could perceive... but then maybe I was failing to understand parts of what the config report was telling me? First the config report, then the things I've tried. Yes, I do realize that I may not be able to "solve" this with a mere browser. I have written some very simple TCP/IP programs with ICS already. Thanks, if only for reading this far! Tom Config report: enter config state. device ipaddress:192.168.0.241 device netmask:255.255.255.0 device gateway:192.168.1.1 host ipaddress:192.168.1.16 connection type:tcp host port:16000 Product Version:TEMPerLAN V1.1 exit config state. Unsuccessful browser strings were as follows. The machine the browser was running in was at 192.168.0.2. Submask 255.255.255.0, I think. I think both are irrelevant... but maybe that's where I'm going wrong? 192.168.0.241 /Unable to connect 192.168.0.241:16000 /Unable to connect 192.168.0.240:81 /Successful connection to my Arduserver, a different device on the LAN, just to be sure I'd got things right! http://192.168.1.1 /Unable to connect 192.168.1.16 /Unable to connect If I could have connected, I would have tried things like... 192.168.0.241?BB 83 .... but there didn't seem to be much point, as I wasn't getting the connections. I don't THINK it is my anti-malware software getting in the way. A PING to 192.168.0.241 DOES get a reply. No reply from 192.168.1.1 or .16 Are there other simple DOS commands I should throw at 192.168.0.241, even if only to check that a proposed path to my goal of software to send the BB 83/ read the reply is going to get me there? -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
