2. Briefly turn the speed knob counter clockwise to the direction
change position. The headlight should shift to a short-short
flash pattern.
3. Enter the units digit of the CV contents preceded by a zero.
For the example of 128, enter 08. The state of the function
LED does not matter. Note: use 80 for 00.
4. Briefly turn the speed knob counter clockwise to the direction change
position. The headlight illuminates continuously for ~1.5 seconds to
confirm successful programming. If programming was unsuccessful, the
headlight will rapidly flash for ~1.5 seconds. The headlight then returns to
the long flash pattern that indicates that the engine is waiting for the next
CV number to be entered.
5. To program more CVs, return to Step 1. To exit programming mode,
turn off track power by pressing the stop button
Note: When entering values greater than 79, the two entries are actually added together.
This applies to both the CV number and contents. Thus it is theoretically possible to
program a CV number as high as 869 (790 + 79).
Operation
Until the engine receives a packet that is addressed to it that uses the new Märklin
format, the single function key directly controls startup and shutdown. If the function
key is on, the engine will run the startup script. If the function key is off, the engine will
run the shutdown script. This allows the engine to be used with controllers that only
have a single function key, such as the Märklin 6020, or a Märklin 6021 with DIP switch
2 in the off position.
When the engine receives a packet that is addressed to it using the new Märklin format,
the normal function mapping is used, with the function key corresponding to function
0(head/tail light).
Bit Function
0 Enable 27 speed step mode
1 Enable 28 speed step mode
2 Enable extra functions at engine address + 1 and consist address + 1
3-7 Reserved
MTH engines support both New and Old Motorola formats. For the Old Motorola
format the Function/Off button on the Marklin 6021 controller toggles
Start-up/Shut-Down. For the New Motorola format the Function/Off button on
the Marklin 6021 Controller toggles the Headlight/Taillight and F1-F4 are
supported. Please see page 22 for the engine's F-Function List.
