Hornby R8245 Sapphire Chip Auto Running?

[Sir TophamHatt]

I've just seen online that it appears you can alter CV 140 in the Sapphire chip and it'll create an element of automatic running.

That is, the loco will trundle down the track, wait for a set amount of time, then reverse back.

Is that correct?

How does the loco know where to stop? Is this also via a CV?

Are there any tutorials about this?

Thanks

There are quite a few CVs that need setting up before it will operate as required.

See the user manual https://support.hornby.com/hc/en-gb/article_attachments/360015937539/R8245-Sapphire-Locomotive-Decoder-Leaflet_1_.pdf

CV140 enables a series of up to four timed events, which can be set by other CVs to repeat, e.g loco fwd at speed xx for yy h/m/s: stop: loco reverse at speed xxx for yyy h/m/s: stop: repeat zz times. As Rog says fairly complex so read the famous manual (RTFM).

Hi

There is a tutorial on you tube about this if you type in auto controller hornby sapphire you will find it it explains what you have to do step by step was filmed about 10 years ago hope this helps

I think it may be worth mentioning that this and more can be achieved by using programs in Railmaster. It assumes you have this of course. May be worth investigating also.

That will be two Famous manuals to read - Sapphire and RM, programming section.

There is a tutorial on you tube how to use the fuel amounts and filling up with fuel on the sapphire decoder I think ay76 does both of the sapphire tutorials

Exactly what I was thinking

[96RAF]

The fuel burn and staged events are two separate capabilities on the Sapphire.

The fuel burn has no other function than as a simple count down timer against loco usage, when it will stop the loco and (if fitted) flash the lights to indicate the fuel is gone, until the Elite ON/OFF button is pressed to refuel the loco when away it goes again. Yes that is what the ON/OFF button is for, not what it says on the label.

The Sapphire staged events are specific speed, direction and duration commands sent in sequence. As there are only four events this can be rather limiting.

As stated by others RM Programs are much more comprehensive in what can be achieved.

I don't have Rail Master and am not really interested in it for this layout.

I'll take a look at the tutorials online though, thank you.
