So - this is "Keyless Ignition - Part Trois"
Now that the Sombra supplies from the 'Part Deux' model appear to be exhausted - have not been able to find any recently - had to come up with another system based on new donor module.
(there may some isolated Sombra units out there but hard to bank on at this time)
See this thread for previous details on the 'Part Deux' - Sombra based model
(includes video demo of operation which is essentially same between the two systems)
So I had to find an alternative. I wanted to have the same core feature, it that it would not only serve as being 'Keyless' but also hands-free.
Hands-free of course means not having to actually remove the remote from your pocket or press the function button, but just have it detect/enable when in proximity of the bike.
I recently got a Directed 2102T PKE (Passive Keyless Entry) to play with as it appeared to meet the fundamental criteria
There are pluses & minuses vs the Sombra.
Plus - EXTREMELY compact; readily available;
Minus - is inverted logic - has active 'armed' signal rather than active 'dis-armed' (which Sombra has as configurable option); no on-board immobilizer relay or lamp flash outputs; only one remote per kit; a bit more expensive.
The latter two in the 'minus' column are not really show-stoppers. But does mean if you want these features, you have to add couple of external relays. (you could argue however the KeyLess as a whole is anti-theft)
To deal with the inverted logic of the 'Armed' vs 'Dis-Armed' active states I had to revise the control circuit.
The remote needs some special attention also: When the remote is in proximity of the controller, it flashes the remote continuously; there is a provision on a car for a remote battery saver however, whereby you press the brake and it turns off the remote; then when car door opens it resets it back on.
So I had to figure out how to turn on/off the remote (bike has brake but no doors!) and also not only latch the ignition output, but also the trigger from the 2102T.
So all of that is integrated into the new control board and remarkably even my prototype still fits inside the incredibly small 2102T enclosure.
I discovered that if I tied BOTH the brake & 'door open' input triggers to the 2102T to the ignition output, as soon as the ignition is set (by pulling clutch lever, same as before) it would turn off the remote and conversely turn it back on when the ignition latch is dropped. No need to tie externally, all comes together at the module!
Here is block diagram of the new controller (the 'Armed' input - now an inhibit rather than an enable):
And here all buttoned up inside the 2102T controller.
This one has a discreet LED harness for the 'Ready' state - it's for a non-Triumph.
On the Triumphs everything will come out of the small connector on the front and integrate through the OEM alarm connector and use the OEM alarm LED in the dash
Functionally, looking pretty good so far!
The kit actually comes with TWO antennas and a provision for an optional third (not included) - however one appears to be plenty for bike operation.
