IR Transceiver (Front Panel) Settings
When connecting the Cinema Reference Mach II to an external control system, you may run into a
data conflict resulting from sending data into the Cinema Reference while it’s front panel IR trans-
ceiver is active. If you are having difficulty establishing communication with the Cinema Reference
Mach II serially, ADA suggests turning the Cinema Reference’s front panel IR transceiver off.
The Out of the Box default is set so that the IR Transceiver is active. To alter the Cinema Reference
Mach II’s IR Transceiver’s state (On or Off):
1 Turn the Mode knob clockwise until the display’s second line reads SETUP MENU and press
the Mode knob.
2 Turn the Mode knob clockwise until the display’s second line reads IR REMOTE and press the
Mode knob.
3 Turn the Mode knob to select between IR REMOTE IS ACTIVE and IR REMOTE IS INAC-
TIVE. Press the Mode knob to continue with other setups. To completely exit the setup
menu, turn the Volume knob.
Address Setup
The Cinema Reference Mach II can be set to a myriad of addresses in the event multiple Cinema
Reference’s are connected to the same network. As such, one can connect a single ISO-232 to the
control system and communicate independently to all Cinema Reference Mach II’s. In order to pre-
vent conflicts here, each Cinema Reference Mach II needs to be set to a unique address (there are
256 available addresses). A point of caution is worth noting here. The concept of putting multiple
Cinema References on the same network, works best if they are in the same location (i.e. central
equipment rack). Second, the units should all be set to run at the optimal baud rate of 19200. Finally,
be certain that your control system is capable of handling the amount of feedback from the units in the
event they are turned on or updating in short order. A single Cinema Reference Mach II will update
approximately 1.5K Bytes of data during boot-up (or update request). Multiply this by the number of
units on the network and you have a fair amount of data. and some control system buffers may
overload. If you wish to connect your PC to a multiple network, it is worth noting that you can actually
select which Cinema Reference you wish to communicate with by selecting the corresponding ad-
dress in the PC software provided. Because ADA recommends that you run the Cinema Reference
Mach II’s at 19200 Baud, you cannot expect to use the IRT-232 to communicate with your PC via IR.
The Out of the Box default address is set to 0. The IR remote controls included with the Cinema
Reference only work if the unit is set to address 0. Altering the address will cause this remote control
to no longer function. To alter the Cinema Reference Mach II’s Address:
1 Turn the Mode knob clockwise until the display’s second line reads SETUP MENU and press
the Mode knob.
2 Turn the Mode knob clockwise until the display’s second line reads PRO SETUP and press the
Mode knob.
3 Turn the Mode knob clockwise until the display’s second line reads NETWORK BUS and press
the Mode knob.
4 Turn the Mode knob to select an alternate address. Press the Mode knob to continue with
other setups. To completely exit the setup menu, turn the Volume knob.
