Hello. I have a few of your products and do appreciate the hard work that must have gone into them. I am posting to ask a question on the 200310 DC Power Supply/Regulator Module. If my testing of this component works out as expected, I will most likely be using it in the manufacture of a new product our company will market. But, I have to make it more user friendly by protecting the existing locking feature using a password or by some other means. This is necessary because other components/processes in our final product could be damaged if our proper settings are somehow modified after purchase. Is this currently possible with this device, if not, could it be made possible by perhaps a firmware update? Thanks for the reply. Very fine product and suits our needs just fine otherwise.
