  @Will-Dickson, thank you! It works for me on my Windows 10 machine!

  I did have some initial connectivity issues, and because my Arduino IDE was old, I uninstalled and reinstalled the latest version of the Arduino IDE to get the latest Windows drivers. The connectivity issues disappeared after that and a reboot.

  It even looks looks like you fixed the units issue mentioned in http://forum.iorodeo.com/topic/421/the-colorimeter-app-v4-is-stuck-on-um-but-the-values-returned-look-like-ppm! Thanks.

  I'll be happy to provide bug reports for me and the people I'm working with.

  I'm also looking forward to having a new v0.6 installer for MacOS, but I appreciate that you prioritized the more pressing Windows issues first.

  Yes, you can connect the +/-15V on the rodeostat to the +/-12V on the multiplexer.

  Earlier revisions of the Rodeostat used a +/-15V DC-DC converter to provide the power rails for the op amps on the Rodeostat. Whereas, more recent revisions us a +/-12V DC-DC converter. The multiplexer is labeled to match the more recent versions of the Rodeostat. However, the multiplexer will operate fine on +/-15V.

  I will reply myself...

  I had to install the FT232R USB UART Driver. Then a USB Serial Converter was installed and the port COM3 was installed after updating the driver

  Now, selecting the COM3 port, it works perfectly.

  Hope it can be useful for other Cheapstat users

  Best regards

  Would you be kind enough to explain how did you achieved that?

  Oh gosh, you are right! I’m sorry for the delay but I was very busy. I have never thought to rotate the LED matrix because I thought I was right with that (otherwise, if not, no LED would have turned on). Thanks very much! I also take advantage of you for another issue. I have tried to load the arena configuration on the SD card but PControl doesn’t let me do that. Have you any suggestion? It seems that the controller doesn’t communicate to the SD nevertheless at the beginning (when the controller is switch on) PControl finds and initializes the SD card. I’m sorry because of all these questions!

  It looks like the RTL8195 has 3.3V IO. The potentiostat shield powers the MCP4261 with 5V. So you are connecting a 3.3V device to a 5V device - I think. I'm not sure if the IO pins on the RTL8195 are 5V tolerant, but you might want to check. Could be related to you issue.

  Note, the MCP4261's could be powered off of 3.3V. They have a pretty broad allowed input range 2.7 - 5.5V. This would require cutting one trace - the one going to the 5.5V on the shield - and rerouting this trace to to the 3.3V pin.

  The spec sheet for the MCP4261 can be found here. http://ww1.microchip.com/downloads/en/DeviceDoc/22059b.pdf
