H. AC Power Inlet
Connects to 100V~120V or 220V~240V,
50Hz/60Hz AC power supply.
I. Power Voltage Switch
Select the power supply voltage to be 100V~120V
or 220V~240V.
Warning: Do not switch the voltage when
the CXM2000 is connecting to the power
supply! Setting wrong voltage will damage it.
J. USB Connector
Connects for firmware update only.
Warning: User must not connect to any
equipment via this USB connector, or the
CXM2000 or any connected equipment may
be damaged.
K. 8-way DIP Switches
Switches 1~4 are for JBL cinema speaker selec-
tion. Switch 5 is for fault detection. Switch 6 is
for 5.1 or 7.1 channel installation system selec-
tion. Switches 7 and 8 are for monitor and fault
detection functions of subwoofer 1 and 2.
Warning: Before setting the 8-way DIP
switches, the installation system must be
correctly wired and the DIP switches must
be set according to the configuration matrix
provided in "Appendix II. 8-way DIP Switch
Configuration" on page 19, or damage
may occur.
L. HD15 Output/Input Connectors
Connects the HD-15 connectors to the Crown
DSi series or XLC series amplifiers through VGA
cables. This allows the CXM2000 to send and

receive signals from the amplifiers for fault detec-
tion and monitor function.
L-Bi-amp: Connects to the amplifier of left
channel (bi-amp speaker) or left and right chan-
nels (passive speaker).
R-Bi-amp: Connects to the amplifier of right
channel (bi-amp speaker) or no amplifier (pas-
sive speaker).
C: Connects to the amplifier of center channel.
SW1: Connects to the amplifier of low frequency
effect channel (subwoofer 1).
SW2: Connects to the amplifier of low frequency
effect channel (subwoofer 2).
Ls/Rs:Connects to the amplifier of left surround
& right surround channels.
Bsl/Bsr: Connects to the amplifier of back sur-
round left & back surround right channels.
Warning: The output connection must
match to the DIP switches configuration.
Please see "Appendix I. Pin Definition" on page
18 to select the correct interface converter for
the XLR connector.
M. HD25 Input Connector
Connects the HD-25 connector to the main
outputs of the cinema processor.
N. RS-232 Connector
Connects the RS-232 connector to the Theater
Management System (TMS) for sending fault
detection results. Please see "Appendix V.
Control ASCII Protocol" and "Appendix VI. Com-
munication Settings" on page 20 for detailed
communication protocol.
Warning: The connection must use dedi-
cated serial cable.
