Welcome to the BBI2 wiki!

Bus Board Interface 2 is a plugin that allows you to operate the vehicle in OMSI 2 using an external serial device.

Communication with the control panel (Sent by the plugin when the value of a variable is changed):

xx:yy:zz
xx - Data type (LV - local variable, $V - String variable, SV - system variable)
yy - variable index (zero-based!) from opl file
zz - The value of the variable

Example:

LV:0:0.67
SV:3:65.0
$V:1:IBIS 2.0

Communication with the plug-in (sent on request by the control panel):

xx:yy:zz
xx - Data type (LV - local variable,TV - Trigger)
yy - variable / trigger index (zero-based!) from opl file
zz - The value of the variable / trigger state (on/off)

Example:

LV:3:5.0
TV:0:1
TV:3:0

The SYSTEM command returns the values of all system variables. (See Communication with the control panel)

Additional remarks

Set serial port timeout to low! (<= 50ms)
Arduino: Serial.setTimeout(50)
