Support for NCE has been started in revision 622.

The protocol is easy, but the sensors have to be polled.
The USB Interface only support a subset of the Command Station RS232 commands!

• Power CAB (USB)
• Power House (RS232)

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.

• 28 and 128 DCC speed steps
• 28 functions
• accessory decoders¹
• programming track
• AIU polling

¹) Untested, please report any problem to help the project team.

All options not listed in this paragraph are not used for this command station.

• Baudrate: 9600, 19200, 38400
• Handshake: NONE
• Device: for example "com1, com4, /dev/ttyS0, /dev/ttyUSB0"

Activate AUI polling.

(11.855+)

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).
