Hornby Elite to DCC Concepts AD S8sx

[collectors]

If i connect a Hornby Elite to DCC Concepts AD-S8sx & give the 1st point address as 20, do i then have to do each one individually?. I only ask as the Hornby points decoder auto allocates the next 3 as 21/22/23. Thanks

Think you have to program each output individually. Simple answer is program the first one and then see if the second output responds to the next number.

AFAIK you set each Learn switch one at a time and when set to the Learn position you then send the address required. So you need to set each output individually via each of the switches on the decoder.

Ok, the next part is i have 2 decoders, would i jut set the 1st decoder from lets say 11 to 18 & the second 19 to 26? I also assume these code numbers are the same as the trains allocated numbers. So i assume you would allocate "lets say" 1 to 10 for trains 11 to 18 for points on decoder 1, & 19 to 26 on decoder 2 & for other possible accessory numbers higher than these.. Thanks

You might get a quicker, positive answer, by emailing DCC Concepts. They are usually very quick to reply. BB

Accessory numbers are separate from mobile decoder numbers. Though they may use the same digits.
When programming accessories most consoles have to be put into the accessory feature to enable them to send the different data.

basically no,
you can still start from 1 for the accessory decoders and the loco, although you see it as 1 the address effectively is accessory1 and loco1
https://dccwiki.com/Accessory_Address
gives a good explaination at the start

this means that you wont end up with some locos addressed higher than the accessroies if you ended up expaning the fleet
as for the consecutive numbering, you can do and if the layout is complete then there is no harm but if you have an area that you think might get some extra points to keep things grouped there is no reason to not leave some spaces so say the station area has addresses 1-10 even though your only using 8 and the fiddle yard has 11-26 and the branch line has 30-34. also on a single decoder there is no need to be sequential so if it makes more sense to have point 4 on the other deocder, if for some reason you wanted all the points on one loop to be the same and all the others to be the next set, which allows the you to keep points numbered close together for scrolling though the menu for the ones you want to operate one after the other.

You can allocate any valid accessory address to any port on the ADS8 decoders but each port has to be added individually. There is no facility for them to be programmed with a block of addresses in a single operation that I am aware of.

So i can have a train a number 1 & a point/turn out as number 1. So when i program a train that number gets listed under locos & the same again for accessory a bit like a filing system. IE: Loco/1, Loco/2 & Acc/1 Acc/2

If you go to the NMRA site and look at the binary code that is sent for an address it is different for a loco than it is for the same numbered point, hence the receiver knows that the command is for a loco or a point.

Its a bit like when you put in a Hornby Acc decoder group address the gubbins knows to allocate the right port address covered by that group.
