MTH PS3.0 Expanded DCC Functionality
Advanced DCC Operation
This section of the manual provides more in-depth detail on how to set up and
configure your MTH PS3.0-equipped engine using the NMRA-standard CV's as well as
the manufacturer-specific CV's. It also explains some of the other F Functions not
covered in the Basic DCC Operation section.
Configuration Variables (CV)
Configuration Variables used on MTH PS3.0-equipped engines.
CV1
Short Address: 1-127 are the valid addresses
CV2
Start Voltage
CV3
Acceleration Rate
CV4
Deceleration Rate
CV5
Max Voltage
CV8
MFG ID. MTH =27 (Also used for various resets)
CV11
Packet Timeout
CV17
High Byte of Extended Address
CV18
Low Byte of Extended Address
CV19
Consist Address (bit 7=1 on an engine will tell the engine it's reversed in a consist)
CV21
Defines active Function F1-F8 for the active consist
CV22
Defines active functions for FL and F9-F12 for the active consist (bit 0=1 will tell an
engine that you want it's FL control to operate under the consist address – bit1-0/bit2=1
will configure the FL control for a reversed engine in a consist)
CV23
Consist Acceleration Rate
CV24
Consist Deceleration Adjustment
CV25
Speed Table Select
CV29
Decoder Configuration
CV49
Short Address (controllers that prohibit PoM)
CV50
Extended Addr High Byte (controllers that prohibit PoM)
CV51
Extended Addr Low Byte (controllers that prohibit PoM)
CV52
MTH/PWM Mode Configuration
CV53
MTH Acceleration (1/8 *sMPH/s) (For example - a Value of 8 written would give you
1sMPH/s acceleration)
CV54
MTH Deceleration Rate (1/8*sMPH/s)
CV55
Factory Address Reset Alternate method. Send a value of 55 to CV55 on address 55 and
the model will go back to the Factory Default Address.
Note: The engine address has to be something other than address 55
CV56
Marklin Configuration
CV57
Anti-Jackrabbit Toggle. A value of 7 disables the feature, a value of 0 enables the feature.
CV63
MTH Consist Acceleration Rate (1/8*sMPH/s)
CV64
MTH Consist Deceleration Rate (1/8*sMPH/s)
CV66
Forward Trim
CV67-
Speed Table Selection (CV29 bit 4 must be set to 1 then CV25 must be set to 0 or 1)
CV94
CV95
Reverse Trim
CV105
User ID #1 – General Purpose use for customer
CV106
User ID #2 – General Purpose use for customer
CV115-
MTH Function Assignments – See table of supported CV's and manual section on how
CV170
to re-arrange them for further information
1. CV52, bit0 must = 1. This will enable PWM Mode.
