Description
Locomotive decoder 76 320 is a very small powerful multi-protocol decoder. It can be operated
in DCC and Motorola digital systems and also runs in analog mode with DC current or with AC
current using the Märklin reversing pulse switching mechanism. The operating mode is
automatically detected and can also be locked manually.
The decoder operates with a frequency of 18.75KHz and is therefore well suited for DC and
especially for Bell armature motors (e.g. Faulhaber, Maxon, Escap) up to a maximum power
load of 1A. Short burst start up currents are tolerated.
Motor characteristics can be controlled either by setting the minimum, maximum and middle
speeds or via various CV’s for individual speed steps.
Load regulation can be control via regulation parameters to a variety of individual motors.
The decoder provides two direction dependent lighting outputs.
Using F3 and F4 a shunting mode for slow speeds and Start/braking inertia can be activated.
The decoder can be programmed with the Intellibox, DCC and Märklin controllers. CV’s can be
programmed with all devices.

Installing a 76 320 locomotive decoder
Connecting the device
Remove the bridging plug from the locomotive and push
the plug from the decoder into the vacant socket.
If locomotive does not react then re-insert the decoder
after turning it over 180 degrees.
Note: If the travel of the locomotive does not coincide
with the indication on the control centre you can change
the value of CV29 bit to 0 to reverse the direction.

Using the double sided adhesive pad provided affix the decoder to the desired location in the
locomotive. The adhesive pad protects the decoder from contacting conducting surfaces and holds it
in place.
Start-up
Double check the correct installation with a continuity tester or an Ohmmeter.
When placing the device make sure it does not come into contact with any conducting surfaces in the
vehicle! Also ensure that a shot circuit cannot occur when the locomotive is close and that the wire is
not cinched.
A short circuit with the Motor, lighting, third rail pickup and wheels can destroy the
device and eventually the locomotive’s Electronics!
Starting up the decoder
Select address 3 on your controller. The will operate in which ever data format it is addressed, in
Motorola or in DCC operation with 28 speed step.
If the decoder is used on conventional layouts it can be controlled either with a DC or an AC controller
(system Märklin). All operating modes are automatically recognized by the decoder.
Programming
In factory default state all decoder options are changed using configuration variables (CV’s) according
to the DCC standard. The decoders can be programmed by an Intellibox, DCC Centre and Motorola
Centre.
Programming with the Intellibox
Irrespective of the format to be driven later we recommend that the decoder be programmed via the
programming menu for DCC decoders.
The Intellibox supports DCC programming with a simple input menu. Long addresses do not have to
be laboriously calculated, they can be entered directly. The Intellibox automatically calculates the
values for CV17 and CV18.
For the exact process please read the appropriate chapter in the Intellibox manual.
Special case locomotive addresses 80 to 255 in Motorola format
In Motorola format the Intellibox supports an address range to 255. Addresses 1 to 80 can also be
programmed freely using DCC programming. However if locomotive addresses higher than 80 are to
be used, the locomotive address must be programmed according to the chapter "Programming with a
Märklin controller".
After programming is complete CV 1 has a value of 0 and the decoder uses the Motorola address
larger than 80.
Programming with DCC devices
Use the programming menu in your DCC Centre, to program the decoder CV’s in either register, direct
CV or page programming mode. It is also possible to program the decoder on the main line using a
DCC Centre.
Refer to the manual for your control centre for full instructions on the process.

Programming of long Addresses without the Programming Menu
For programming with a centre which does not support programming with an input menu, the value for
CV17 and CV18 must be calculated. Here is an example for programming the address 2000.
•
•
•
•
•
Divide the addresses by 256 (2000:256 = 7 remainder 208).
Take the result (7) and add it to 192.
Program this value (199) into CV17.
Program the remainder (208) into CV18.
Important: Set Bit 5 of CV 29 to 1, so the decoder uses the long address.
Calculating the CV value
With CV29 and CV49 various characteristics of the decoder may be established.
The required values are easily calculated using the CV table and simply addition.
Example:
Normal travel direction
Value = 0
28 speed steps
Value = 2
Auto Analog/digital change over Value = 4
Speed steps via CV 2, 5, 6
Value = 0
Short address
Value = 0
The total value is 2.
This value is factory default for CV29.

Programming with a Märklin Center
With a Märklin center all CV's can be programmed, but not read.
1. Switch Center off and on.
2. Select the address of the decoder and switch the light on.
3. Operate the direction change-over 5 times in quick succession with the stationary locomotive
(speed step 0), until the light turns off.
4. Set the speed controller to "zero". The rear light now flashes slowly 4 times.
5. Enter the number of the CV that is to be programmed.
6. Briefly operate the direction change-over. The rear light flashes fast 4 times.
7. Enter the desired value for CV e.g. a locomotive address.
8. Briefly operate the direction change-over. The rear light flashes slowly 4 times.
If further CV's are to be programmed repeat points 5-8.
If programming is to be terminated switch the center to "STOP" or set the address to "80" and briefly
operate the direction change-over.
Since a Motorola digital center from Märklin only accepts inputs of 01 to 80, the value "0" must be
entered by entering the address as "80".
Page-Register for inputting CV-Numbers greater than 79
CV addresses larger than 79 can only be programmed with the help of the page register, CV66. If
CV66 has a value higher than 0, then the contents of CV66 times 64 will be added to every address
entered. The entered value must lie in the range 1 to 64. When leaving Motorola programming mode
the page register (CV66) is set automatically reset to zero.
Example
If CV82 is to be programmed with a value of15, then CV66 must first be programmed with a value of
1. Subsequently, CV18can be programmed with a value of 15. The decoder places the value 15 into
CV82, which id derived from the multiplying the contents of the CV66 (in the example 1) by 64 (thus
64) and then adding the entered CV address (18).
Offset-Register for entering CV values greater than 79
CV values larger 79 can be programmed only with the help of the offset register. The offset register is
CV65. If CV65 contains a value > 0, then all following programmed valued are calculated by
multiplying the contents of CV65 by 4 and adding the result to the entered value. When leaving
Motorola programming mode the offset register (CV65) is set automatically reset to zero.
-3-
Example
CV49 is to be programmed with a value of 157, then CV65 must first be programmed with the value of
25. Subsequently, CV49 can be programmed with a value of 57. The decoder places the value 4 * 25
+ 57 into CV49.
Note: When programming CV65 and CV66 the contents of the offset and page registers have no
effect.
Märklin braking section
The decoder reacts to a Märklin brake section (brakes with analog power on the track), if CV29 bit 2
and CV49 bit 7 are set to 1 (factory setting 1 and 0).
