Chipping a Saxon

stevelewis


Hi  Steve  Lewis
 
Did  you  buy   a  volume  control   to  fit  on  yr  Massoth  decoder?
 
I  meant to  mention  it  before  they  are  quite  inexpensive  and  do    allow  easy  volume  control  wthout  having  to  alter  the  volume  CVs    I fitted  one  to  Keith  Ts  Saxon  and  it  protrudes  into  the  cab  via  the   hole  where  the  switch used  to  be! To  assist in  turning  it  I adapted  a panel pin  and drilled a  small hole thro the control knob  to  form  a  'T'  bar,
 
Keith  will prob  advise  if  it  still  works  OK??
 
Regards  The  other  Steve  Lewis

No need with the Navi just go to CV200 and adjust to your level can be done on the track. But not when running

It WORKS!
PARDON?

From a whisper to a roar.

Moving on then. As Phil recommended I drilled a series of holes directly below where the speaker fits and also two smaller holes for the self tapping speaker screws. Word of caution here, when drilling small hole do not put your fingers underneath the frame to support it, Don't ask but it hurts...

The speaker in situ. The chip I just used one original hole and drilled a new hole for the other screw into the Lead/ metal, its fairly soft so a self tapper found its way in fairly easy

OUCH!

Now comes the wiring bit. First of all just a simple solder the two wires onto the speaker and that plugs directly into the top of the chip. The power bogies were not as simple as the 4 wires from each one where all colour coded BLACK.. As pointed out by Steve Lewis (not me) I  had to find out which two where the pick ups and which two where the motor supply. Quite simple for me, I took them to work and gave them my electrical engineer, who then marked up which one was which. He tested the pick ups via his meter and the motor direction by a 9v battery. The power bogies where then wired together and connected to the chip as per Massoth instructions

Good choice of speaker.
I've been using the slightly larger FRS 7 in many of Casey Jones' locos for a few years now.

The speaker came with the chip Neil, although Phil recommended this make of speaker as well.

STOP PRESS, I've just plucked up the courage and stuck it on me test track and everything WORKS, the sound is LOUD and good quality and both power bogies go the same way as well. Think me next step is to change some CVs for me lighting and smokey generator which on this loco are 5 volt

they are an impressive set up that combo.

A quick question if I may:  from previous postings can I take it the volume knob is not mandatory with the XLS decoder?    It doesn't need the connector pins bridging or anything like that, if no knob is used?

KentKeith asked me to check over a bunch of (believed dead) decoders a little while ago, including an XLS for which so far I've only tested that the motor drive works.    If the volume knob is not required (I should check CV200 to set the volume?)  then I only have to worry about plugging in a speaker to test the sound?  Is there a  "sound on/off" function key that also needs to be on? 

I really must study the manual for the XLS (not used one myself yet).

Cheers

PEter think if you use an exteral volume switch CV 200 should be set to 255. Default 32 on & off should be F6

Vol control  knob  not  mandatory,  but  I  find  in  practise  it  is  more  benficial  to have one saves  time  if   wanting  to reduce  vol quickly.,
Nothing  has  to  be done  if  Vol control is NOT  used.
 
Check  CV200   to  ensure  that   it  is not  set  too low,  cant  put  my  hands  on  an  instruction  book at  the  mo  but  CV value  of  64  rings  a  bell  for  FULL volume
 
From  memory  F1  may  be  the  on / off function
Unless  of  course  the  functions  have  been altered  in  which  case  it  may  be  worth  doing  a  factory  reset on  the  decoder, if  the  decoder is thought  to be  faulty  then   this  is  probaly  the  first   action  to  take  anyway!

F6 on the Massoth system is sound on/off

The volume Cv200 is factory set at 32 but can be changed from 1 up to 63.
Sounds like I know what Im on about dunt it, I've just read the manual.

By the way 32 on the volume is loud, I can easily hear it upstairs and the locos in the conservatory so god knows what it would be like at 63.........

most of mine are set to 7 steve..i find it nicer to lose the sound as the locos amble round the garden.. altering the volums a doddle on a navagature

Nearly got this thread mixed up!

Told you they were good Steve. Listen to your uncle Phil

Phil, he can't hear you for that darned sound system!

Never thought about that Neil

Might be having discussions with the neighbours
