Then, projection may be interrupted. • The service life of components or lamps may be reduced due to the long-term effect of the ambient temperature if the installation distance is not appropriate. • If the projector has to be installed in a box or a closed environment due to the installation requirements, the external intake and vent system should be designed additionally to ensure that there is enough air for cooling or the projector will not be surrounded by heat.

17 Connecting the Projector to Other Equipment Follow the instructions below to connect the DU6871/DW6851/DX6831 projec\ tor to the video source, external control equipment (if any) and AC power supply� When connecting to the equipment, use the correct signal cable to connect to every signa\ l source and ensure that the cable is securely connected� Fasten the nut on the joint and connect the signal source equipment to the projector according to the figure below. Connecting to the personal computer You can connect the PC signal to be projected to the projector through th\ e DVI-D, HDMI, DisplayPort, RGB or RGBHV (BNC) cable� If the signal to be input is VGA signal, connect the VGA cable to the external display to simultaneously monitor the projected s\ creen� Connecting to the video equipment Connect the video equipment to the input port of the projector via the D\ VI-D, HDMI, DisplayPort and Component Video Connector cable� DU6871/DW6851/DX6831 DLP Projector - User's Manual
18 Connecting to the control equipment The projector has the following control port for connecting to the contr\ ol equipment: 3D sync signal transmitter (IR) • HDBaseT/LAN (Network control): The projector supports network control� 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 network� Refer to the remote control guidelines for detailed information� • RS-232 (RS-232c control): The projector supports RS-232c serial control� The projector can be remote-controlled by connecting the projector to PC or \ control system through the standard 9-pin serial cable (Straight Through Serial Cable)� Refer to the remote control guidelines for detailed 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 input port to expand the working range of the remote control� • 3D Sync Out: 3D IR sync signal transmitter � Note: • When the terminal of the remote control cable is inserted to the wired control terminal of the projector, the projector will automatically switch to the wired control mode and cannot be controlled through the IR signal of the remote control. Disconnect the wired control terminal on the projector if you want to control through the IR signal of the remote control. • 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 whether the port is correct before insertion. DU6871/DW6851/DX6831 DLP Projector - User's Manual
19 Connecting to the Screen Trigger If your projection system includes the Electric projection screen and ot\ her 12V trigger device, you can connect these devices to the 12V trigger to output and configure the output 12V signal settings, such as automation and the aspect ration of 16:10 throu\ gh OSD control to Trigger� The projector will output 12V signals according to the current settings \ of the aspect ratio and trigger when turned on� You can use the signal to control the screen or device� Screen DU6871/DW6851/DX6831 DLP Projector - User's Manual
20 Connecting to the External HDBaseT Transmitter The projector has a built-in HDBaseT signal receiver� With the HDBaseT Transmitter (optional), the video, RS-232 and LAN signals can be sent to the proje\ ctor via a single RJ-45 cable� If the HDBaseT Transmitter you purchased supports the input and output of the IR remote control, the control signals from the IR remote control ca\ n be sent to the DU6871/DW6851/DX6831 projector via the RJ-45 cable� VGA INRJ45 Lan HDMIRS232RJ45 HDBaseT YPbPr VGA Cable DVD PlayerDVD Player Hub RS-232c RJ-45 Cat5e or above Control PC Control PC HDBaseT transmitter Projector Note: • The projector supports the video signal, R-232, IR remote control and the reception of the network control signals but do not support Power over Ethernet (PoE). • Set the Control->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 cable and baud rate will switch to 9600. • If the command is sent via the HDBaseT transmitter, the longest transmission distance is 100 meters. The projection 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, interfere signal transmission, reduce the transmission distance and degrade the image quality. DU6871/DW6851/DX6831 DLP Projector - User's Manual
