Connection to a PC with Serial Interface
For central remote, the serial interface of the star coupler can be
connected to a PC by means of a serial cable. Pins 7 and 8 of this cable
must be jumpered. (Note that this deactivates FO Input channel 1).
The serial interface distributes data to the four FO channels and receives
data from these channels.
