#135 ~ Decodering

Installing, Wiring, and Programing a TCS KAM4-LED Decoder.

Train Control Systems Keep Alive Decoder for LEDs.

Hot Glued the decoder to the ceiling right in the center of the car.

The wiring is pretty straight forward except that the Red wires are attached to the trolley pole bases and the Black wires to all wheels:

Red = Trolley Poles

Black = Wheels

Orange = Motor

Grey = Motor

Blue = Lighting Power Bus (positive (+) ).

White = Headlight (-)

Yellow = Rear Headlight (-)

Green = Forward Interior Lights (-)

Purple = Rear Interior Lights (-)

Programing

With the Digitrax Zephyr

Programing the new address to #135:

1. Place car on the programing track.

2. Press 'Program Mode' on the Zephyr. until display reads as 'dir'.

3. Press 'LOCO' button. Display reads 'Ad2' for addresses 1-127, press again to display 'Ad4' for addresses 128-9999.

4. Press '1' and '3' and '5'. Display will read '0135'.

5. Press 'CV-WR'. Display will blink the 'Ad#' and then '0135'.

6. Return the car to the mainline to test it.

Some CV's need to be changed.  The Green wire (forward interior lights) defaults to the Function 1 (F1) button which is fine. But the Purple wire (rear interior lights) defaults to the F2 button which is a momentary contact button normally used for locomotive whistles (the whistle sounds when the button is held down). Which means that the interior lights on car #135 only light when the button is held down. So the purple wire needs to be remapped to the F3 button instead.

Digitrax Zephyr Function buttons. 

I need to remap the Green wire (CV 35) from function button 2 (F2) to function button 3 (F3).

Even though these trolley cars are bi-directional I have designated the open section as the forward end of the car to simplify things (the open section is easier to see into so I want to put my motorman figure in that end). 

Green wire (CV 35) = Front                Purple wire (CV 36) = Rear.

To remap the button-

Program:     CV 35 V=4  (simply confirm this value since this is the default)

                      CV 36 V=16 (from the default value of 8)

Remapping CV's is easiest using JMRI Decoder Pro

Otherwise its button mashing on the Zephyr:

1. Place car on the programing track.

2. Activate 'Program Mode' on the Zephyr. Program Mode light lights up.

3. Press the 'CV' button. Display reads 'ad2' or 'ad4'.

4. Press '3' and '6'. Display reads '0036'.

5. Press the 'CV' button again. Display still reads '0036'.

6. Press '1' and '6'. Display reads the value of '0016'.

7. Press the 'CV-WR' button. Display should blink once as it writes to the decoder.

8. Return the car to the mainline to test it.

And that ought to do it!

Yes sir!

That oughta do it!

№ 9 ~ Official Portrait

The San Diego Electric Railway opened with great fanfare on September 21st 1892!

But by the time № 9 stopped for its photo much of the fanfare had moved on leaving one official, two patrons, a motorman, and a conductor to pose with it.

San Diego Electric Railway № 9

This marks the first time I've photographed a completed scene on my layout. Finally! But the layout is far from complete.

Here's the set up. Pretty simple.

Some people model historic battle scenes, some people model fantastic sci-fi scenes, I model everyday life of old San Diego. What does that say about me? I don't know. But if you know, don't tell me- I don't want to know.

Yes Sir! I don't want to know.

TCS Keep Alive DCC Decoders

Installing A DCC Decoder In A Poor Running Model Yields Surprising Results!

One of the advantages touted by DCC proponents is that it improves the performance of motors. So I decided to add a TCS Keep Alive Decoder to my poorest running model to see how it fares:

A Huntington Standard by Oriental Models.

It features a crappy open-frame motor and all brass gears ( usually alternating brass gears with plastic gears produce much better performance).

And wouldn't you know it, I was able to get decent performance out of it. In this short video I was able to run the car around the block with some realism:

Yes sir! Decent performance!
