Blocksignalling auto reverse REV2 quires.

[collectors]

Help on a couple of questions, please.
I must say 1st that i thought that when i was purchasing this unit with what i thought it had an auto frog switch built in, as it says connect frog to the inner loop of track. “But which inner loop rail” & still not quite sure. So i sent BS an email & the reply was, i am better to use an auto frog like the Gaugemaster. So, not a good start.
So, my 1st question is on the main track before the loop there are connections from my DCC bus to terminals “IN1 & IN2”, then the next 2 terminals “OUT1 & OUT2” i connect another 2 cables to the track, which is the same thing. “Isn't it” & wasn't sure why?.
My 2nd question was, do i use a separate power supply rather than take it off the DCC bus. Thanks

Assuming the entrance/exit point is an Electrofrog point the points frog wire connects to the loops inner rail shown as red.
The Main line tracks are all fed from the modules 'Out1' and 'Out2' terminals Not directly from a DCC bus pair fed from the Track terminals of the DCC system.
You need a 12 volt DC power source to feed the unit separately.

To be honest its probably not the best of reverse loop devices for the DCC user! Their REV1 would be a better option or use a PSX-AR.

Thanks, Brian, but unless they forgot to show it on the diagram? does this mean the incoming track has a pair of insulated joiners further down the incoming main line? before it gets to the loop.

Just got a message back from Block signalling saying, "With DCC you wire the loop to the OUT1 and OUT2 if you want" So i assume leave my dcc up to the points as is, as my 4 IJ's are on the points out. This all makes more a lot more sense, but on the original drawing, it still doesn't say if the incoming track should be isolated. We hopefully will test in the next few days.

Putting IRJs to the left wouldn't work as the rails each side of these IRJs would at some stage be 180 degrees out of polarity with each other as the REV2 flips the main tracks polarity not the loops!

Their idea is somewhat rather strange, in that they appear to say that the REV2 feeds all the main layout from its output two terminals. Where as normally the main layout is fed directly from the DCC console and an input is also taken to a RLM. Its output then feeds the isolated loops rails. Their method is completely the reverse!!

Now that makes much more sense. Just 4 IRJs needed to totally isolate the loops rails as per any other RLM
The incoming track and the point are all feed directly from the DCC system or Bus pair of wires. Only the actual isolated loops rails are feed from the REV2 Output. No other rail feeds must be allowed to connect onto the loops rails between entrance IRJs and exit IRJs.

Just an updated image if needed.
