1. Introductuion

   Annuncicom 100 have two COM ports available, COM1 and COM2, both phisically
   located in the DB9 connector, in the front panel.

   As reported in the pinout below, COM1 is the RS232 port, COM2 is the RS485.

   For the X8 connection, both ports can be used, but since X8 device communicate
   trough RS485, if port COM1 is used, a special adapter cable is required.
