The computer interface is set to a transmission rate 115200 Baud by default.
The USB LocoNet interface in the Intellibox II can be used with Windows 2000, XP, Vista
and Windows 7 operating systems. Support for Windows 95 and 98 Systems is not

For layout control all PC control programs that support the LocoNet protocol can be used.
14.1 Interface Characteristics
The Interface operates with the following Baud rates: 19200, 38400, 57600, 115200.
The connection between PC and LocoNet is electrically isolated.

14.3 Communication PC - LocoNet
(only for Experts)
Communications between the PC and LocoNet must be according to the following schema:
Send a message over the USB and wait until the message is echoed, before sending a
new message. Process any other messages that are received during the waiting time.
new message. Process any other messages that are received during the waiting time.
LACK (Long Acknowledge Message) processing: if a LACK message can follow a
message (see LocoNet documentation about messages for which a LACK can be a
response), a flag in the ComPort must be set after the send and receive. If this flag is set
and the next message is a LACK message it must be processed because it is a reply to the
sent message. If the next message received is not a LACK the flag is cleared. This
ensures a LACK is not processed for the wrong message.

Evaluating and Processing received Messages
By echoing transmitted messages that are initiated by the PC they don’t have to be
separately processed, as, after the transmission to the LocoNet they are located in the
receive buffer and are handled by the receive routine.

NOTE: Sending of messages without control of the echoed message can lead to errors in
communication between PC und LocoNet. By using a Baud rate of 115200 Baud this
control will not lead to a reduction in communication speed.
