A list of hints relating to the NCE and Wangrow System One systems

NCE / Wangrow Serial Communication

The serial port works at 9600 bps. Setting it to a faster speed will not work, as the system lacks the handshaking capability to manage communications. JMRI doesn't allow speeds greater than 9600 for this reason.

This mostly impacts the Power House Pro and the Wangrow System One command station. (NCE supplied the software to Wangrow.)

NCE Serial and USB Interfaces

A number of commands present when using a serial cable are not available when using the NCE USB interface. Of the commands that are available, the computer interface can send any command it wants.

Drivers

The NCE USB uses the SiLabs CP2102 chipset. Use the SiLabs CP210x drivers from SiLabs available here. There is a universal driver for Windows10. You also need to know if your OS version is 32 or 64 bit, and install the appropriate driver.

Limitations

All Systems

Clock unavailable. Turnout monitoring unavailable.

SB3

No programming track support, operations mode only.

Power Pro

No mobile decoder programming.

Auxiliary Input Unit (AUI) Support
  • USB versions 7.x and above, Smartbooster with firmware version 1.65 and above support the AUI
  • USB versions less than 7.x, no AIU support

Consisting

This is important if you take your motive power to run on another layout which uses NCE equipment when you do not use an NCE system on your own layout.

NCE uses a hybrid version of Advanced Consisting which they call Intelligent Consisting.

  • Always break up any consist you created with an NCE command station before removing your locomotives from the layout. Failure to do so will render the units immobile when placed on a layout which does not use an NCE DCC system.

If you forget to do that and find you can not get the locomotives to move, write a value of "0" (zero) to CV19

Power Pro

Clear All Consists

The "Clear All Advanced Consists" command available in the NCE Power Pro sends a Clear Consist Address command, which causes CV19 to be reset, This is done using the Broadcast Address. All decoders on the track must obey Broadcast Address commands.

Reset Cab ID Number

  1. Press the PROG/ESC key five times, to go to Set CMD Station
  2. Press the ENTER key 33 times, scrolling through the menu options. The last option is Clear All Cab Memory
  3. Reboot the command station
  4. Each Cab must be plugged in, one at a time, to register its existing Cab ID, which is stored in the cab.

Operations

NCE Decoders and RailCom

With an update to the NMRA DCC Specifications, older NCE decoders which were compliant are no longer. The issue arises when RailCom is active on the command station.

When RailCom is enabled, older NCE decoders may operate erratically or with unexpected results. Disable RailCom to prevent these issues should they arise.

Command stations made with RailCom on board cause the issue. Not all manufacturers1 support RailCom. Most older systems lack RailCom capability. See your manuals to learn if your system has RailCom, and how to disable it.

Mini Panel

The Mini Panel is a throttle class device. It can instruct the command station to create commands to one or more preprogrammed loco addresses.

Cab Reset

To reset any NCE throttle including the Power Cab: Press SELECT LOCO button when plugging the Cab in, then release button. Reading or changing the cab address is now possible.

With the cursor blinking, select a new address, or enter 00 to reset the cab to its factory defaults. Press ENTER when finished.

If no changes are desired, just press ENTER to exit.

Programming Issues

Power Cab

If you do not have a dedicated programming track, the load presented to the Power Cab may be too great, which will result in a failure to program and CV read back will not work. It is also likely that every decoder on the rails will also be reprogrammed.

Solution: Create a dedicated programming track.

Ops Mode Programming

Decoder_Programming#Operations_Mode commands can be sent to any decoder, it does not require pre-selection via a throttle.

Computer Interface

The serial interface (USB or serial) can send any command.
