Connecting to the Control Equipment
The projector has the following control port for connecting to the contr\
ol equipment:
3D sync signaltransmitter (IR)
• HDBaseT/LAN (Network control) : The projector supports network control via LAN/
HDBaseT terminal. LAN and HDBaseT share the port. If only network control is used, 
you can connect the LAN on the projector to PC or through the local netw\
ork. Refer to 
the Remote Communication Guide for more detail information.
•  RS-232 (RS-232 control) : The projector can be controlled by RS-232 command via 
connecting the projector to PC or control system through the standard 9-\
pin serial 
cable. Refer to the Remote Communication Guide for detail information.
•  Wired remote control : If the projector cannot receive the IR signal from the remote 
control due to the overly long distance or obstacles, you can connect th\
e cable to the 
IR remote control or the external IR transmitter (optional) via the WI\
RE port to expand 
the working range of the remote control.
•  3D Sync Out : Connect to 3D IR sync signal transmitter.
Note:
• If the wired remote control cable or the external IR transmitter is inserted to the incorrect port, such as 
Trigger, the remote control or the IR transmitter may be damaged. Make sure whe\
ther the port is correct.

Connecting to External HDBaseT Transmitter
The projector has a built-in HDBaseT receiver. With HDBaseT transmitter (optional), the 
video, RS-232 and LAN signals can be sent to the projector via a single \
RJ-45 cable. If 
HDBaseT you purchased supports to output the IR remote control, the control sig\
nals from 
the IR remote control can be sent to the DU6675 projector via the RJ-45 \
cable.
VGA INRJ45
Lan HDMIRS232RJ45
YPbPr
Note:
•  The projector supports the video signal, R-232, IR remote control and th\
e reception of the network control  
signals but do not support Power over Ethernet (PoE).
•  Set the INSTALLATION -> RS232 -> Channel on the OSD menu to HDBaseT if you want to use the 
external HDBaseT transmitter to send the RS232 command to the projector via the RJ45 cab\
le, the baud  
rate will switch to 9600 automatically.
•  If the command is sent via the HDBaseT transmitter, the longest transmission distance is 100 meters. The 
projector may be interrupted or interfered, or the control signal cannot be sent if the transmission distance 
is exceeded.
•  Use the RJ-45 Cat5e or above cable and avoid entwining. Entwining may cause damage, poor signal 
transmission, or reduce the transmission distance and degrade the image \
quality.
