SFX0416 SoundFX+Function Decoder
|
Return To Top |
|
Features:
Wired Mobile Decoder with SoundFX™+Accessory type functions for most HO scale Locomotives.
Preloaded with selectable steam and diesel Sound Schemes
Includes 28mm 8 Ohm Speaker & 330uF Capacitor
Please Note: The SFX0416 has no motor functions and is to be used in conjunction with a standard mobile decoder such as a DH123D etc.
Regarding N Scale applications:
Although the SFX0416 decoder PCB is physically small enough to fit into many types of N Scale rolling stock and dummy locomotives, for N Scale applications the standard 28mm speaker would have to be replaced with a smaller device.
Finally, the SFX0416 is an 'add-on' type sound decoder, meaning it traditionally works with a standard DCC motor decoder in locomotive applications. N-Scale locomotives generally do not have the necessary space for both the SFX0416 and a motor decoder, as such the SFX0416 is not suitable for these applications.

A Note about Steam Chuff/Cam configuration: CV133 and CV134 work together to control chuff timing:
CV133 Steam Chuff/CAM config, 128=>EXT cam, 1-127=>DRIVER dia in inches[63]
CV134 Steam gear ratio trim, 32=100% ratio, [32]
Setting CV133's value from 1-127, puts the SFX064D into 'Autochuff' mode. Autochuff mode tells the decoder to simulate driver chuff timing in software. The CV133 default value is 63, approximating a real-world loco driver diameter of 63 inches. If you halve this figure you will effectively double the chuff rate for a given loco speed.
CV134 (gear ratio) also effects the Autochuff rate. The CV134 default value of 32 assumes no gear reduction. Doubling this value to 64 tells the decoder to simulate a 2:1 gear reduction thereby doubling the chuff rate. CV134 and CV133 work together to create the desired chuff rate in your locomotive.
A final note on Chuff support - Setting CV133 to a value of 128 tells the SFX064D that you want to configure an actual cam input on your locomotive. CV134-->128 tells the decoder to activate the white cam input wire on the 10 pin sound harness of the SFX064D (see diagram below)
A chuff will be triggered when a pulse of over 6 volts or DCC track voltage is seen on the white CAM input lead. This voltage has to go off (0 volts) before the next chuff can be triggered.

Additional notes:
Question:
I am installing a DH165A0 in an Athearn SD70. The Head light outputs are a nominal 30 ma (with the link cut). The bulbs I am using are a bit lower in their current demands and [my lamps keep burning out].
Is there any way to lower the current output from 30ma, or do I need to add a resistor in line with the bulb to drop the voltage output? Of course, if it is supposed to be a regulated current output this might be a problem.
The Theoretical Answer:
The DH165A0 has a constant current source for F0F and F0R, so a series resistor will simply increase the terminal voltage at the selected fixed current.
To drop the lamp current, add a resistor in parallel with the lamp to bypass some of the current selected, calculating value for the resistor: (R = Lamp Voltage / amount of current to divert). If the resistor is too small a value it will bypass more of the current and the lamp will be dimmer. You can try a number of values to get the best "fit"
A More Practical Answer:
If the filament lamp is burning out, try putting a 47 ohm resistor in parallel. If it's still too bright, gradually *decrease* the resistor value.
