A single headed mast can only indicate speed.

To be clear, the prototype _can_ use single-headed masts for many different things, beyond the "typical" use in ABS signal systems.

Two modeled cases with which I am familiar, which existed in real life include:

- Ann Arbor Railroad's color-light "train order signal" at Cadillac, MI, which shows that the train need not pick up orders at the station, or the need to pick-up one or more "train orders" before continuing, shown as a flashing-red or flashing-green lamp; or

- C&O Clifton Forge Yard's color-light "scale movement" signal, which can give a "direction indication" - as in "back-up and re-weigh the last car".

In general, a "signal" that looks like an ABS signal, but which must be interpreted in some other way, will be given a "different" aspect to allow crews to interpret it correctly, and/or the signal will be specificly "called out" in the "special instructions" of the Timetable, with interpretation instructions.

JMRI's "SML" generally _does not_ directly apply to these "non-ABS" uses of single-headed signals, though. A JMRI User _could_ use a "signal mast" or a "signal head", _without SML_, with some other logic (Jython, Logix, etc) to model this.

You misunderstood Ken, he meant what is on Com 4 is not the NCE device

Thank you for reporting this. It's probably a mistake in the decoder configuration - the ESU function output configuration is a lot and I'll need to spend some time on it to update JMRI to match all the options on all the outputs on all the decoders for the most recent firmwares (we're also still missing class light logic and dynamic sound).

Can you open an issue on github for me to remember this: ? If not, let me know and I'll do.

Terry M,

Well that's clearly not a NCE-USB device. It may be that both parts of
the driver are not installed for the NCE-USB. One part deals with it
at the USB level of device. The second driver makes COM device to
that. Sometimes trying to install the driver twice works.

But one trick in Device Manager is to go to the View tab and then
select "Show Hidden Devices" and you might get to see some partially
installed devices.

EN-Tact,

If you see the offline indication, that means the command station is
not responding to commands from JMRI.

Dave,

Post the link to the page you were downloading from so we can check it
out. I had said about 150M for the size.

That tells me that what is on Com4 is not your USB Interface and that the computer is not seeing the USB Interface.
I'm thinking it's a driver issue, drivers needing to be installed.


I can't help any further as I know nothing about NCE.

Ken,

Dwarf signals are typically used in low speed applications, so a dwarf green would be Slow Clear, and a high green Clear. This could be done with a dwarf on the siding and high signal on the main.
