Hi Barry, Are you really getting power If so then you should be getting changes into your control chip. As always do not make changes in programming when other engines are on your layout. Preferably do it on a program track or in OPS mode make sure all your other engines are off the board. I am guessing you are trying to give it it’s own address first. I don’t know your hornby system but all systems when changing the address you don’t want to have any other engines on the track. You should be going to program how ever your system tells you how to do that. enter the number you are giving your engine and press enter. when the engine is accepting the new address your engine should roll forward a couple of clicks. Exit your programing and see if it will run on the new address. If not check the original address. If you have lost control and don’t know where you are at then go back your your factory default settings (on Digitrax you go to CV 8 and adjust that CV to oo8 and enter. You should be back yo your original address of 03 from the factory. Which ever system you have the programming should be the same only your system should tell you how to get to that. Always press enter when you make the change and before you quit programming make sure you exit. The computer is the best way to make changes though. JMRI will do a better job getting it where you want to go with it everything from speed adjustments to sound and acceleration / momentum which I don’t recommend till you are used to the system and your engines All DCC systems will work similar and your CV’s will be the same. How you get to where your system gets you to the proper CV you will need to follow your system. Just remember that if all else fails reset to factory settings and youe engine will go back to a 03 address and just start over.
If you use the JMRI on your computer and the link unit to your track once you get your engine set you can save all the settings to that engine. So if you loose control again all you do is recopy all the changes for that engine back on the engine and you are ready to go again
I hope this is a good start for you as not really knowing where your problem is. One other thing find someone like at a club or something and let them program your engine and and watch them do it. It does not have to be your system. Once the settings are set you can take the engine to any DCC layout with other systems and it will work there as set. One word od advice though. If you are going to another system with your engine and you consist it to another engine while there, Make sure you unconsist the engines and dispatch your engine and exit his system before going home and trying to run it. I found that even though the systems work alike they also wright the systems in their own writing so Like you consist the engine there when you get it home it will most likely not move. You either take it back to your friends layout and properly unconsist and exit or you will be resetting back to factory settings to reprogram your engine. Yes that happened to me and my friends layout was over an hour from me so I elected to go through the resets and start over. Once you get programming down it works pretty well either from the trottle or from the computer with the JMRI program Actually easier on the JMRI. Good Luck from Newman

Throw the Hornby controller away, I personally think they are rubbish and believe they are not NMRA compliant. Try a NCE powercab, they are excellent.
