The protocol is easy, but the sensors have to be polled.
The USB Interface only support a subset of the Command Station RS232 commands!
The Power Cab systems require a separate USB interface board from NCE.
The Power Pro (Power House) systems include a serial port on the command station. If desired a serial (RS-232) to USB converter can be used with the Power Pro system.
Activate AUI polling.
The version number is important for polling AUI units. The USB NCE uses a different command for polling…
AIU broadcasts must be disabled for proper operation.
In Rocrail, the sensor addresses can be calculated from the AIU address: sensor address = AIU address * 16 + number of input - 1.
Number of connected AIU's (14 bit sensor modules, max. 63)
The first AIU address.
If the first AIU has address 10 then the Offset must be set to "10". All following AIU's must have consecutive addresses (so 10, 11, 12 etc).
