Questions abut QSI install

Electronics Power and Sound
#1

I got tired of waiting for CVP to release the new airwire card, so I went and bought a QSI magnum, G wire and programming pack.

I have few questions about the install. I’m running battery power (14.8 LiIon) with the airwire 900 controller and this is going into a B-mann K-27 of which has been gutted so all wiring is done from scratch.

When wiring in battery power, I assume it goes into the track pickups? This would be the safe guess but I can’t find anywhere that confirms it.

My next question is wether or not I can make an interface access plug? I like that feature of the Phoenix P5, I can plug it in and play with the sounds while the loco is running. Is there anyway I can do this with the magnum?

Lastly, can I control the marker lights independently without an auxillary board? I can’t quite figure out what they are explaining for this.

I’m sure it’s just me, but I found the manual they sent kinda vague and a lil hard to figure out. I’m sure I’m just rooted in my AW and P5 ways :slight_smile:

thanks for any help!

Well, I found out the answer to my first question and maybe the second.

The battery does go in at the track hook up. But as far as wiring an interface plug it is “advised” to put in a DPDT switch to change over to track pickup for programming mode. I typically use a DPDT switch to go from battery to charge mode.

When the loco is in program mode using battery power, and the battery/track switch is switched to track, does the programmer/interface then power the card? If so then could I put in a DPDT switch after the battery/charge switch which could control battery power or interface options? The interface side could be fed from a port, say a simple male female jack instead of track fed. My reason for wanting this is 1: I typically do my changes or programming out on the track via my laptop, 2: my loco has no track pickups anymore and I don’t want to take it apart again to install them.

The magnum has four spaces for track input (2+ 2-) If the battery is using one pair, could I put the interface in the other? Does it need to be isolated from battery power? Would the battery then charge the interface port as well? I would think it would and I couldn’t do this, but I guess if I don’t ask I’ll never know.

Oh, and if I’m programming with the QSI programming package, did I read correctly that I have to disconnect the G wire cable? Or is this only if the loco is equipped to run on DCC track as well?

I’m still wondering about the marker lights.
