Important to rememberImportant to remember

All outputs from JMRI are called “turnouts” All outputs from JMRI are called “turnouts” whatever they do. They are held in a whatever they do. They are held in a “Turnout Table”. “Turnout Table”.

All inputs to JMRI are called “sensors” All inputs to JMRI are called “sensors” whatever they do. They are held in a whatever they do. They are held in a “Sensor Table”.“Sensor Table”.

CBUS turnouts are MT...(think CBUS turnouts are MT...(think MMERG), ERG), sensors are MS...sensors are MS...

Let’s create some Turnouts.Let’s create some Turnouts.

Do Do NOTNOT add add “MT”, it is added “MT”, it is added automatically.automatically.

Remember CBUS is event driven & JMRI Remember CBUS is event driven & JMRI “turnouts” are JMRI outputs.“turnouts” are JMRI outputs.

So no So no pointpoint [!] using the node number of the [!] using the node number of the point motor module (CANACC4 or 4).point motor module (CANACC4 or 4).

Instead use the node number of the producer Instead use the node number of the producer (CANACE3 or ACE8C) whose events have (CANACE3 or ACE8C) whose events have already been learnt by the point motor driver.already been learnt by the point motor driver.
