After the serial connections are made and the enclosure is
powered, your matrix goes through its startup sequence.
Your
half-Y
is now ready for operation via the DB-9 port.
C.2 Operating Serial Controllers
An external controller is any device capable of sending ASCII
characters serially. External serial controllers may also
receive information from the matrix via the DB-9 port.
Examples of external controllers are PC or Macintosh
computers, and third party serial control devices. The
half-Y
can optionally support up to two external serial controllers.
Each type of external controller is specialized for different
types of applications, but they all allow remote access to the
distribution matrix.
C.2.1
Entering BCS Commands
AutoPatch Distribution matrices are programmed using a set
of ASCII characters called Basic Control Structure (BCS).
BCS command syntax is designed to parallel the operations of
the control panel. So instead of pressing the keys on the
control panel, press the keys on the external serial controller
keypad.
