DCC Install

I bought this Hudson used (thanks Nick!) and it has a Zimo MX695 Rev C,  installed by Train LI, specifically Dan Pierce.

This section will have unique / customized settings here, go to the Zimo Decoder Tips page for general stuff on the 695

This unit has a modified Aristo smoke unit, wired directly to the fan and the heater. Power comes from the +10v common for the heater, the fan is powered from 5v.

Basic settings:

CV28 = 3 (all RailComm on - Broadcast + Data)

CV250 = 227 (MX695 rev. C)

CV251-253 = 88 (serial number)

CV 7 and CV 65 = 34.00 software version 34, sub version 00

CV260-263 = 184, 207, 216, 164 = special code to allow Hudson file to be reloaded
