Setup for the IntelliBox-I 'Classic'.

Intellibox-I can be used with the original Märklin p50, the extended p50x or the LocoNet protocol.
The p50 protocol is not advised because of the very limited instruction set.

In basic setup go to “Interface” and then select:

• Baudrate: 19200

In basic setup go to “Interface” and then select:

• Syntax: 6050 & IB (“IB only” would not work)

The number of the connected 8 port sensor modules. If you have 16 port sensor module you must multiply this value by two.
Leave the poll checkbox unchecked for better performance. This is a work around for Tams Easy Control.
The Poll option starts reading sensors in the p50 way, Märklin 6050/6051, which is not needed for the IB because it provides 'events' for this.

1. Upgrade the software inside the Intellibox to at least version 1.500
2. Put the interface into mode “LocoNet”:
   • Basic settings → interface → syntax → LocoNet
3. Set baud rate to 19200 Baud:
   • Basic settings → interface → bit per second → 19200 bit/s
4. Set the UART of the interface to 1 stop bits: (default 2)
   • Basic settings → special option → SO 5 → 1
5. CTS flow → SO 6: (default 254)
   • Basic settings → special option → SO 6 → 0

Do not activate the slotserver, this will conflict with the IB and could lead to a Rocrail server crash.

If you are facing FIFO problems in auto-mode you should consider to use the following special options of your IB.

Keep in mind, to change only one setting at a time, test and validate, before changing another.

• All known special options: ib-so.pdf

To increase stability on Rocrail connecting with IB, esp. when using the actual release, consider to change Special Option 26 from 1 to 0.
SO#26=1 forces Long RS-232 break to result in fallback to initial 2400bps, this may happen during p50x-module startup, resulting in a potential loss of communication, while SO#26=0 results in remaining speed unchanged.

To access the highest transfer rate (34200bps) of the IB, which is not available in the options' menu, change SO#1=4.

If no I²C devices, like Märklin keyboards or so, are connected to the IB, changing SO#33=0 will reduce internal overhead of IB.
SO#33=1 default echo of turn out commands on the I²C-bus.

Rocrail and the Twincenter are known to work with the following settings:

• Interface Baudrate 19200
• Syntax “IB only”
