So you do have Ethernet ports on your CPUs?
No. I don't have Ethernet ports on the CPU's. Right now, the design incorporates a sealed, portable Pelican case with several Brad Harrison connectors on the sides of the case for connection of power and control cables. When you open the cover of the case, you gain access to a faceplate that has a c-more, sealed breaker reset buttons, a sealed power switch, and a sealed USB port. Inside the case behind the faceplate, the USB port connects to a splitter that allows the single external USB port to connect to both the C-more and Do-more programming ports. When a technician needs to check on the system or modify the settings, he opens the cover, does his thing, and then seals it back up.
It is certainly possible for me to modify the design to swap the Do-mores to the Ethernet version, to add an Ethernet switch, and to install a sealed Ethernet connector on the faceplate. In the future, I'll certainly consider designing all new systems to operate using Ethernet even if it does add to the cost. The problem now; however, is that if I convert to Ethernet, I have to try and recall units back for modification, process a design change, modify the units, requalify the units for field service, and provide the units back to the end users. In additon, if all of the units don't get returned for upgrade, I then have to maintain 2 versions going forward. All of this is doable, but before I went down that road I wanted to make sure that there wasn't a command that would allow me to stream out to USB, or some program out there that allows me to connect over the USB port. I still don't understand why I can't get the data by exporting the data view that I was using the other day to look at the logged data on one of the units. I could see the values, and when I right clicked and picked export, a CSV file was created, but it was empty. I don't have a unit in the shop at the moment cause I loaned out my development unit, but when I get it back I'll try playing with the the data view option some more. (Data View would only let me look at 99 values at a time. Maybe it will not export if you have that many open?)
Rather than do all the hardware modifications, I think I'll wait on the device being developed by BizwareDirect. Their engineer expects it to be available around September and he expects it to cost less than $100. If I do decide to convert to Ethernet instead, then I'll set up a stramout loop to cycle through the data and send it over Ethernet.
