Chris,
It should be able to operate any accessory decoder, it shouldn't matter if it's a 4way or 6way, your only going to select the address from either 1 to 4 or 1 to 6 (depending on what you set the address as in the first place)
I used the Lenz LS150 with a separate 3amp power supply which is the maximum you can put into it.
I found it would sometimes not throw the points.
The points took that much current it triggered the overload cut out in the LS150 so you have to turn the power on/off to reset it.
From past experience I now use accessory decoders that have built in CDU's that way the nice burst of current is enough to throw the points, plus you don't need a monster power supply, as the CDU only requires a small amount of current to 'charge' the capacitors.
Having just read the Dynamis manual it is a little confusing!
It shows that when you press mode to enter accessory mode the screen will
show:-
ACC A001 :01/1:
It states this would be accessory address number one, decoder number one and output number 1 if using a 4 way decoder.
So in the example it
says:-
ACC A067 :17/3
Which means accessory address 67 which is on accessory decoder number 17 output number 3
It does say that there is a limit of 100 addresses which would be 25 accessory decoders each with 4 outputs.
It doesn't really tell you how to program any accessory decoders though just to refer to the accessory decoders manual...the EZ accessory decoders at that.
I'm still sure any other type would work though.
If you used a 6 output accessory decoder then using address 67 as in the example above I would expect the display to
read:-
ACC A067 :12/1
So accessory address 67 would be on accessory decoder number 12 output number 1 when using 6 output decoders.
If not then it seems like it may take a little working out unless you can actually change the default to a 6way output.
Cheers
