legacy base and controller issues and questions

Did you program your asc's and bpc's? Are you using a 6-14192 or 6-14191 cable
set? Little more info might help.

Bill

Bill I am using a cab 1 base to run my asc's and my bpc's and tpc's. I did hook up up the cable that came with my legacy set as per the Lionel video, however my cab 2 has no effect on operating these, but my cab-1 will still function and run all of them. I made my own cable to connect my cab-1 base to my controllers. I would assume the cable pin-out is still the same. If so should not the legacy base operate these or am I missing something in programming my cab-2. Hope this helps. chief

Plugging the old cable from my cab-1 into my legacy base seems to do nothing as well any ideas. chief

What I understand is with the Y cable that came with the legacy, you have it plugged in the cab 1 and legacy base and then out to the tpc etc. In this set up
the cab 1 works and legacy dose not.

did you watch this video?

I just did will do more work on my setup. thanks chief

How many devices do you have hanging on the base output? In another post someone mentioned that the Legacy Base is only rated for driving 4 devices. (Personally, I hope this is incorrect!)

Dale if you mean controllers suchas asc's etc. I have 2-tpcs 10-ascs 6-bpcs. My old cab-1 base runs everything just fine however when I plug the cable from my old base into my legacy base nothing will respond. I can however load and run tmcc engines just fine. My cable is a home made one so maybe the db-9 female connector does not extend into the base enough. Not sure I could get a new base cable and hook up one controller and see how that works. Any ideas appreciated. chief

I believe you are just overloading the Legacy's output. One other poster here has had to resort to multiple "boosters" on his Legacy Base, and he has fewer units than you.

Newer isn't always better.

The cab1 base had a transistor that pulled the output up to 5 vdc, I think more capable of being loaded than the cab2. I found that with just about a 500 ohm load, I pulled the output of the cab2 down from approx 8vdc to about 3 1/2 vdc and it would no longer drive a single TPC. FWIW, a load of about 1K ohms lowered the output to about 5 vdc and the TPC responded ok. I would not be surprised to see a buffer amp product on the market for the bigger layouts using the cab2.

That well could be the case Dale, but it sure seems like a step backwards from tmcc. Power to run these however is pulled from another source and does not rely on the base to power them. Only dat and com come from the base. Chief

It's not the power to run the devices that is loaded, it's the additional load on the dat and com wires that gets loaded down and will no longer drive the devices with data inputs.

A booster shouldn't be that complicated a project, that's RS-232, right?

I think you need a power master bridge.

Right.

Powermaster Bridge? That doesn't have anything to do with driving the DAT and COM lines for accessory controllers and TPCs.

I meant "right" to the RS232...and the powermaster post snuck in before I clicked

Not reallly. It is "RS-232-like", operating within the narrower voltage swing of zero to five volts, and sourcing substantial current.
