JMRI Decoder Pro with NCE Power Cab and SB5 Settings

Posted by on Mar 3, 2016 in Tech Specs, Tips DCC Components |

Here are the correct settings for JMRI and jumpers for the NCE Power Cab and NCE SB5.

It also explains how to read the version of your NCE USB . Only the first digit counts; the last three digits report how your jumpers 2-4 are set and jumper 1 is ignored on all systems.

Power Cab Instructions
=================
The correct settings for a Power Cab V1.65 or V1.28 (as shown when the Power Cab starts up) and an NCE USB V6 (or you are not sure of the USB version) are:
— All USB Jumpers off (or at least 2, 3 & 4. Jumper 1 is ignored).
— JMRI preferences are:
— System manufacturer: NCE
— System connection: NCE USB
— Serial port: <whatever is appropriate for your system>
— USB version: V6.x.x
— System: PowerCab
— Additional Connection Settings checkbox ON
— Baud rate: 9600.

The JMRI console log should then report V6.3.0.

If it reports V7.3.0 and your Power Cab is V1.65, use the settings below instead.

The correct settings for a Power Cab V1.65 and an NCE USB V7 are:
– All USB Jumpers on (or at least 2, 3 & 4. Jumper 1 is ignored).
– JMRI preferences are:
— System manufacturer: NCE
— System connection: NCE USB
— Serial port: <whatever is appropriate for your system>
— USB version: V7.x.x
— System: PowerCab
— Additional Connection Settings checkbox ON
— Baud rate: 19200.

The JMRI console log should then report V7.3.7.

SB5 Instructions
============
The correct settings for an SB5 and an NCE USB V7 are:
— USB Jumper 4 on. All others off (or at least 2 & 3. Jumper 1 is ignored).
— JMRI preferences are:
— System manufacturer: NCE
— System connection: NCE USB
— Serial port: <whatever is appropriate for your system>
— USB version: V7.x.x
— System: SB5
— Additional Connection Settings checkbox ON
— Baud rate: 19200.

The JMRI console log should then report V7.3.1.

If the system does not work after this and your USB is V7:
— If your SB5/Power Cab is V1.65 rather than V1.65B, you may have been affected by a firmware issue (triggered by a System Reset).
— Your NCE USB may be set to a bad cab address.

In either case, go through the following :
— Quit JMRI.
— Ensure neither LED on the NCE USB is stuck ON. If so, power cycle the USB by unplugging it from the cab bus cable.
— Ensure you have no other throttles connected.
— Restart JMRI and immediately go to Configure USB Interface under the NCE menu.
— Set the Cab ID to 3.
— Attempt a JMRI operation (use a throttle, Identify a decoder.
— The status line should stay green and it should work
— If this does not work, do not fiddle with any other settings but instead:
— Observe whether the Cab Bus LED on the NCE USB is stuck on and report back.
— Use Help->System Console…->Copy to clipboard and paste into a post for us (or an offline email).
