Ok, new direction. It just isn’t worth the trouble it would surely cause returning these modules so they are yours to keep. I am still interested in making a carrier for the module so go ahead with the design. You can also put the holes for the xport connector. Holes are cheap. lol
The board size is 3" x 2.3" with 4 x 0.125" holes spaced in 0.150" from each edge.
It will be interesting to see what cost estimate will come out for this setup. That is:
$53 - for Matchport B/G (Order 100 at a time from Gridconnect)
$46 - XPort …
??? board plus the Ethernet connector plus magnetics…
I will also continue along with some other ideas as well…
Simply use the Matchport for the RS232 communications. Use wireless camera (+$25 for trendnet TV-IP110) Probably cheaper than using XPort and camera runs at full speed.
Also been looking around at different wireless IP cameras, to try to find one that might allow other things to plug into them. I have found a couple like (brickhousesecurity.com/ipcam … ubid=27492) but nothing so far that I have found any good information on. It would be great if all we had to do was to mount the camera, and plug in some form of connection from the camera to the robot… I suppose one could try to hack up one of the cameras that have pan/tilt in them and try to intercept that as controls to the robot, but again DIY and not sure how fast those signals can change…
But Regardless I think you could start setting up the software for the control panel and probably make it reasonably independent of the underlying communication method. That is you can have a configure camera dialog that the user probably needs to specify the IP address and port number. This will probably be true for all of the different methods mentioned above…
Likewise will need some form of communication setup for serial link. For many of the different options, you will probably again need to specify a comm port and a baud rate. For some versions may want to specify a few other options, For example xbee may want to do a query to find out which modules are out there and choose. For Some of the Ethernet based solutions, not sure if you will be able to choose the IP address/port or will assume that has been mapped for you externally. Also not sure if you will have some form of configuration with it. Each of these input methods could define some form of IO function to call to send a packet and to receive packets…
The rest of the stuff could be reasonably independent of the underlying link…
Footprint is the pattern that goes on the PCB for a part. Sparkfun has a selected list of parts and schematic symbols/footprints to go with them. Saves having to “create” the schematic symbol and footprint if an Eagle user hasn’t done it already for you.
Sorry guys, we had high winds up here last week and we lost 3 LARGE willow trees(one was over 5ft in diameter!), one of them went through our barn so i’ve been a little DiStRaCtEd cleaning up the mess(willow trees may look nice, but they are filthy trees to cleanup…). I’m ordering an Xport and it should be here by the end of the week or next Monday anyways. Just have to come up with a board to interface this with the Matchport b/g and start testing. Jim it is really nice of you to let us keep these eval boards and modules, thank you…
Well this project was intended to be a vehicle for demonstrating the video capability of the new Flowstone programming environment. I have decided to replicate one or two of the more popular modified router methods to get this going. We will start a new thread for the project when we get further along.
Although it’s not what we had in mind originally, we should go ahead with the carrier board. I think I will scale back the number of boards though.
The MatchPort Demo board schematic shows an integrated 140-306-R (?) RJ-45 connector; although I haven’t found a BOM. I need to know the manufacturer and the correct part number. It appears to be the shielded part.
I’ve used the Halo part before, but I need to know the specifics of the turns ratio, and
inductance of the recommended part.
Jim, do you have a contact, or could you contact them?
Thanks!

Edit:
Actually, if you want to use the XPort, I guess that would be the XPort footprint. THAT, I’ve found, looking for the MatchPort.
Here sharing best information for you. To design a prototype PC board to carry the Lantronix WiFi Module for controlling an SSC-32, and other options yet to be defined. The end result is a remote piloted rover controlled from a laptop computer. We will provide the front end, using FlowStone graphical programming environment.
The Lantronix modules were a dead end. No support, extremely high cost with no reasonable discount structure for making it part of a product. No thanks!
