LIAN / SIMO-Operation mode

The Pleiger-telegram only works with a set direction frequency of 90 Hz. When recognized by SIMO during recording the message 'Sync OK' appears. Only then telegrams can be received. For transmission or simulation in SIMO the synchro-(direction-) frequency must be activated. This is done by the command 'SYNC 90'.
