Con necting the MX82 to the track or a power bus
The ac ces sory de coder MX82 is con nected with the
red and black wire
to
the track or the power bus com ing from the com mand sta tions track out put.
Po lar ity is ir rel e vant. Any num ber of ac ces sory de cod ers may be con nected
in par al lel since their own power con sump tion is ex tremely low.
NOTE: Con necting the ac ces sory de coder to the track is only prac ti cal if the track sec tion con -
cerned is con nected it self di rectly to the com mand sta tion or booster.
An ac ces sory de coder must not be con nected to a sec tion of track that is con nected to a track sec tion
mod ule with oc cu pancy de tec tion be cause the small cur rent con sump tion will cause the track sec tion
mod ule to in di cate an oc cu pied track that in re al ity is not true.

Con necting the MX82 to accessories
DOU BLE COIL SWITCH MA CHINES AND SIG NALS:
Such ac ces so ries are con nected with
3 wires.
The blue wire sup plies the power and is con nected
to the com mon wire of the turn out and the grey and
or ange wires are con nected to the sin gle wires.
MO TOR IZED SWITCH MA CHINES AND SIG NALS:
Such units are con nected with
2 wires.
The blue
wire is not needed in this ap pli ca tion. The other
wires (grey/or ange) are con nected with the switch
ma chine. The power-on time has to be pro -
grammed with CV #515, 516, 517 de pend ing on
the sub ad dress used.
EPL SWITCH MACHINES (LGB):
EPL switch ma chines are elec tri cally iden ti cal to the
mo tor ized switch ma chine (see above). The de fault
power on time of .2 sec onds can be left as is since the
ac tual switch time of the EPL ma chine is rather short.
SIG NALS:
Com mer cially avail able sig nals have a com mon wire
that con nect to the blue wire (pos i tive) of the de coder.
The sin gle wires are con nected with the or ange and
grey wire.
Pay at ten tion to po lar ity in case of LED’s (only sig nals
with com mon an ode) and use an ap pro pri ate re sis tor
(usu ally 1Kohm).
