Icellama21,
So you just run the CUWIN 3500 as a computer and then hook it into your network via the ethernet cable? Is this how you hooked it to the M1 using RM?
It has a fully functional windows CE 5.0 install on it. Just connect a DC power source to the terminals and an ethernet cable to the jack and its connected to the internet. Just like hooking up a PC. It has an IE browser built in and a USB-host port that supports HID devices(I tested composite keyboard, mouse) and flash drives.
Software is installed via activesync from a windows PC, same process as installing software on a cellphone, etc. If you have activesync installed the elkRM installer automatically sets it up to be installed when you connect to the device. Just make sure you install only to the flash drive or to a SD card. It is difficult to remove/reinstall software that was written to RAM due to the registry being in flash, but the files being in RAM.
ElkRM runs pretty well, although the computer does lock up every week or two. I'd recommend hooking the power supply to something close by, an output, swtich, etc. Rebooting requires power-cycling and it has always booted and connected to the M1 very quickly. Read the manual online, I have it configured to automatically run elkRM in full screen mode on boot.
The touch-screen isn't amazing, but works fine with a finger and the large buttons. Using a stylus or retracted-pen is useful to configure settings or use the on-screen keyboard(quite a pain, recommend real kbd for anything complicated). For the price it rocks, but I wouldn't compare it to a Q1.
