I operate the Massoth DCC system. I have four mts switch contols working successfully 1-16 which were programmed when I used MTS. I now have a secondhand Dimax 8156001 which I am unable to program even though I have the instruction booklet. Yes I am reading the English section but it might as well be in Chinese. Can anyone provide a basic step by step way to program for points 17 +. I do have a separate test track wired to control centre. Thanks Roger
