SIGNALS . . .
The MX82 is most of ten used for
sim ple red/green sig nals
(2 as pect sig -
nals),
which represents the same logic as for a turn out. The MX8 or MX88
would be the better, more eco nom i cal choice for multi as pect sig nals.
The re is only one dif fe ren ce what CV’s are con cer ned com pa red to tur nouts
the po wer-on time has to be set to “0”, for con ti nu ous po wer. Of cour se, the
same re la tions hip ap plies bet ween the sub ad dress and the ap pli ca ble CV
(#515 for sub ad dress 0, #516 for sub ad dress 1 and so on).
Of ten a
prototypical slow sig nal il lu mi na tion and dim ming
func tion is
de sired. The CV #546, 547 and 548 can be used to achieve this; typ i cal val -
ues may be: CV #546 = 15, CV #547 = 10 and CV #548 = 15.
Those val ues
are ap pli ca ble to all lights con nected (up to 4 with an MX82V). There is no
re la tion ship be tween these CV’s and the sub ad dress in con trast to the
“power-on” time (CV # 515-518).
If the paired func tion of light bulbs (2 with MX82E or 4 with MX82V) is not
pos si ble or de sired and there fore
each bulb con trolled in di vid u ally,
set
the ap pro pri ate Bit in CV #552 to “1” (ones digit for the or ange/grey and tens
digit for yel low/white wires).
Nat u rally, the user in ter face (cab, com mand
sta tion...) may need to be con fig ured ac cord ingly so that sin gle light bulbs
can be con trolled with ease.
ELEC TRO MAG NETIC DECOUPLERS . . .
A decoupler is treated as a sin gle func tion. In case of an MX82E, CV #552 is
set to 1 and in case of an MX82V to 11. Mixed op er a tion is also pos si ble with
the MX82V (or ange/grey wires for a turn out; yel low/white for decoupler).
SERVOS . . .
4 logic level out puts (sol der pads) are pro vided for the con trol of ser vos
(MX82E as well as MX82V). Each of those out puts can be con nected to a
stan dard servo con trol in put. The power for the servo (5V) is not gen er ated
by the MX82; an other source is re quired (see chap ter 5).
An MX82 can, if so de sired, op er ate up to 4 ser vos
si mul ta neously
with
so le noid or mo tor ized turn outs (or sig nals)
or
ex clu sively
.
At ten ti on:
The 4 servo con nec tions are set
to the next higher ad dress
by
de fault
through the CV set tings #553=110 and #554=132: the ser vos do not op er -
ate with the ac ces sory ad dress stored in CV #513 and 521 but rather ac -
cord ing to the val ues in CV #513 and #521 + 1. For ex am ple: If ad dress 36 is
se lected, the ser vos op er ate at ad dress 37 and Func tion keys F0, F1, F2
and F3.
If you wish to op er ate the ser vos with the ba sic ad dress as in CV #513,521
(ad dress 36 in this ex am ple), the CV’s should be pro grammed to CV
#553=10 and #554=32 (omit ting the hun dredth digit in both CV’s = ba sic ad -
dress) and #545=99 (im por tant! This turns off the “usual” out puts for turn -
outs).

The op tional
“Ini tial Pulse”
(CV #549) is to as sure that all turn outs will be in
the same po si tion af ter the lay out is booted up, as they were be fore the lay -
out was turned off. If all pulses were sent to all turn outs at the same time, the
power sup ply could be over loaded. To pre vent this, dif fer ent val ues can be
en tered to CV #549 which spreads this load over a wider time frame, up to
15 sec onds.
For
con ti nu ous po wer out put
(most ly sig nal light bulbs)
,
CV #515 (or 516,
517, 518 de pen ding on sub ad dress) has to be set to “0”. In this mode the
op ti on of slow il lu mi na ti on and dim ming is also avai la ble (CV #546, 547,
548), which is an espe ci al ly pro to ty pi cal way of sig nal ope ra ti on.
Changing CV #550, Bit 0 (De ac ti va tion of turn out po si tion feed back) is sel -
dom re quired. This pos si bil ity is there in case some body is sen si tive to the
noise gen er ated by the turn out po si tion rec og ni tion func tion but also (rather
un likely but not im pos si ble if used with other sys tems) in cases where the
feed back pulses could in ter fere with the com mand sta tion or boost ers (e.g.
Track power turned off due to short cir cuit in di ca tion or dis torted DCC data).
