I have read repeatedly here that after doing a decoder install to test it first on your programming track before running on your layout. How does one do that? I have always assumed there is no connection between the two functions in a command station. BTW, in my case, system is Digitrax DCS100/PR3/JMRI. Thnx all.
You can't test on the program track, it doesn't provide enough power to run the loco.
What people mean by "test on the program track" is to read and write some CVs - if the loco is miswired such as a short in the motor wires, it won't program, but the low current of the program track will usully keep it from being damaged. If the loco programs OK, it's a good indicator that it is wired correctly - although there could still be problems with the lights and other function wiring. At least the track pickups and motor drive are OK if it programs.

My office is next door to the train room. I've been thinking about getting a Sprog and connecting it to the office computer and an 8' test track so I can program decoders, test and speed match in the office.
That would kinda be "testing on the programming track".
I have the right to remain silent. By posting here I have given up that right and accept that anything I say can and will be used as evidence to critique me.
I have the very setup that Carl mentions and it is a handy setup to have. I keep the DecoderPro roster files on a common network drive so I can access them on the layout or the test-bench and any changes I make are common to both systems and kept current.
On my test track I have a double-throw-double-pole selector switch and an MRC Tech III power supply with volt and amp meters so I can check the current draw of any DC locos before installing a decoder.
I was using an Acer laptop in the shop but just today a refurb HP 8200 mini PC arrived that, I hope, will be faster than the Acer.

Thnx Randy, that explains my confusion. Obviously I have yet to attempt an install but the day is coming.
My first step after installing a decoder is to read Cv8 on the program track. It should successfully read the manufacturer's number (e.g., LokSound = 151). If that works, I try to write a CV to change something.
If that works I go to program on main and change the address, try the headlight, throttle and sound. At that point, I know things are ok and it's worth tweaking other things.
