The Cinema Reference Mach II is capable of being fully controlled via RS-232, providing status feed-
back of all preamplifier aspects. This makes the Cinema Reference Mach II ideal for integration with
advanced control systems. It also permits the Cinema Reference Mach II to be setup and controlled
from its custom PC software setup and test program (Cinema Ref. II PCOS).
ADA Bus Data Port
The primary two-way data port on the Cinema Reference Mach II is the four-pin
screw terminal (ADA Bus) port on the back of the unit. Here, pin 1 is the ground
terminal and pin 4 provides power (+15-24VDC). Pin three is the control input (In or
RX), taking control signals from external devices for operating functions on the
Cinema Reference Mach II. Pin two provides feedback output (Out or TX).
ISO-232 ADA Bus to RS-232 Wired I/O Device
When connecting to a control system (touch-screen based system), you
will require an ADA Bus to RS-232 convertor box, ADA’s ISO-232. This
device not only permits two-way RS-232 communication but it also incor-
porates isolation, preventing ground loops in the control system from im-
posing noise into the Cinema Reference Mach II. The ISO-232’s two jumper
pins need to be in the horizontal Normal position for communication to oc-
cur.
RS-232 Connection & Settings
When only a Cinema Reference Mach II is connected to a control system, the ISO-232 plugs directly
into the back of the Cinema Reference Mach II. The control system connects its RS-232 output to the
ISO-232 using a straight-through 9-pin D type connector. Do not use a null-modem cable. The
Cinema Reference Mach II’s communication settings are: 8 Data Bits, 1 Stop Bit, No Parity with either
a 1200 or 19200 Baud Rate.
