Address mapping
Read the Addressing page for more information about addressing schemes.
| CBUS (FADA) → LocoNet (MADA) | Remark |
|---|---|
| address (divided by) 2 → port | |
| address (modulo) 2 → gate | In the GCA50 setup the gate is referred by the C2 option. |
| LocoNet (PADA) → CBUS (FADA) |
|---|
| (port-1) (multiplied by) 2 + gate |
| gate | value |
|---|---|
| red | 0 |
| green | 1 |
Example
| CAN-GC2 | |
|---|---|
| CBUS | LocoNet |
| Address= 8, Port=0 | Address=0, Port=5, Gate=red |
