OK, here's my tale of woe. Got hooked on digital running at a friend's track. The original plan was to budget for and convert my analog setup over to digital in about a year's time. He moved away, leaving a digital junkie with nowhere to get a fix
. Shortly thereafter, a deal came along that I couldn't pass up, moving the plan ahead by about 12 months but throwing the financing completely out of whack. I acquired the following digital equipment:
• C7030 V1.2 power base,
• 2 straight lane changers,
• 5 curve lane changers,
• 4 lane power base,
• 5 controllers.

I will obtain a C7030 to PC serial cable and get one of the available race management software packages (open to suggestions), but that will absolutely end the cash outlay; i.e. NO Simple H, NO PBPro, etc. However desirable these options may be, this project's budget is DEEP in the red and will receive no further funding at this time.
The analog layout is 65 feet long, mounted on an L table made from two sheets of 4x8 plywood. Good flow running either direction. Regulated 10/12V power supply wired through custom driver stations to the track with 3 jumper points.

So here's the plan:
• Swap the C7030 and two straight lane changers into the existing layout (curve LCs don't appear to be very popular and there are very few places they'd fit in this layout anyway).
• Wire up the lane changers with their own separate 12 V power source.
• Keep the analog wiring and driver stations intact so the track can be run in either mode (power disconnected to whichever is not in use).
• Make up adapter plugs to run the existing analog Lane 1/Lane 2 regulated supplies to P1/P2 on the C7030. The power comes from a pair (one for each lane) of industrial quality regulated supplies (as in +$500, bomb proof, rock steady) that will deliver 10 or 12 volts (switch selectable) @ 4 amps each, 8 amps total. I acquired a dozen of these when the company I work for updated their data collection system electronics - not super high amp output but lots for the cars I run, they are very reliable, stable, and the price was right (free
).

Would like to be able to run up to 6 cars, limited to stock Scalex motors (or even lower power 3 watt motors - close racing much more important than fast racing). I'm hoping that with the lane changers on a separate external power supply, the C7030 V1.2 will prove to be reliable and be able to provide a reasonably consistent racing. I'm aware of the stock mosfet's rather dismal voltage output drop as amp draw increases, but hoping that sticking to low power motors will keep the fluctuations within an acceptable range. Does the Digital Power Base need to be isolated from the track when the rails are getting analog power (via relay, switch or similar)? Any other pitfalls I'm not aware of?

Comments and critiques appreciated.

cheers

Thanks for the replys Ade, Greg. Looks like I'll be adding a relay cutout to the power base to isolate it whenever it's not receiving power. And be obsesive abou track/car tidiness. Sadly, yes the bits I'm not using in this setup are the the bits that nobody else wants to pay much for (curve LCs and 4 car power base) so not much to be gained by selling them off, also as you point out Greg, there's potential future uses for them. Still haven't decided which way to go when I do upgrade. The 7042 has everything built in but still seems to be limited in power output. Simple H and PBPro is a bit of a hassle but lots of power and appears to be more open ended re software development. One of the reasons I want to keep pure DC analog power is I really enjoy proxy racing (which is predominantly analog) and am a bit wary of the pseudo analog power provided by either digital system in erms of how a car tuned with it will perform on a "pure" analog track.

Anyway, thanks again. Will keep your advise in mind as I soldier on with the setup on hand.

cheers

Thanks for the info Geg, I'll look into your suggestions. So much stuff to learn, just starting to scratch the surface here. Sonds like a C7042 is the cleanest solution, guess it's time to start saving pennies for one. And yes, hopefully sometime in the future we will have enough racers here in 'toon town to put together a routes track with a full set of pit stalls, fancy "best line" chicanery, etc.

Lesee, photos of my track - hmm... this forum seems to be real persnikity about what photos it can link to, can't seem to point to the "other forum" or my online storage, so will just have to try a link to Picasa album and see if that works:

Track

Still a work in progress (aren't they always
).

Thanks Riko - guess I'll just run her till she blows then, and do the mosfet upgrade after that happens
.

cheers
