error may occur.
• CAT.6 FTP can be used up to 100m.
• CAT.5E lower rating is not supported HDBaseT. CAT.5E supports 70m.
• If HDBaseT cable is used, the cable should not be bent or rolled, it should be
straight.
• HDBaseT cables should not touch the power 110 V/220 V cables. It should not
be in the water.
• Depending on the HDBaseT transmitting device, the screen of external devices
may not be displayed.

ENGLISH
The HDBaseT Cable Install
• LAN cables are fairly resilient. Yet, any rough handling, such as tight tie wraps,
clamping or stapling can damage the cable, compromising performance or even
preventing signal transmission. Tie cables loosely with appropriate cable wraps.
• Another important issue for cable integrity is the bend radius. Bend radius is
the inside curve of the cable during and after installation. It is best to keep the
minimum bend radius at least at four times the diameter of the cable.
• Cables should be kept at a distance of at least 30cm from power cables. In an
environment prone to high EMI, it is best to use shielded cables.
• If possible, avoid patch cords or cables altogether, as every connection
introduces losses in the transmission. If absolutely necessary, make sure to use
less than two per cable run and keep each less than five meters from the end.

Network Setting Warnings
• Use standard LAN cable (connect to Cat7 or higher with RJ45 connector, 10
Base-T, or 100 Base TX LAN port).
• Resetting the modem may fix some network connection problems. Turn the
power OFF, disconnect and reconnect it, and then turn the power on to solve
the problem.
• LG Electronics is not responsible for any network connection problems or any
faults, malfunctions, or errors caused by network connection.
• The network connection may not work properly because of network settings or
the Internet service provider.
• DSL service must use a DSL modem; and cable service must use a cable modem.
Since only a limited number of network connections may be available, projector
network setting may not be used depending on the contract with Internet
service provider. (If the contract does not allow more than one device per line,
only the already-connected PC may be used.)
• A wireless network can experience interference from other devices that use
the 2.4 GHz frequency (wireless phone, Bluetooth device, or microwave oven).
Although interference can also happen when using the 5 GHz frequency, it is
less likely to occur.
• The wireless environment can make wireless network service run slowly.
• Failure to turn off all local home networks may cause excessive traffic on some
devices.
• The access point device must support wireless connections and wireless
connection feature must be enabled on the device to have AP (access point)
connection. Contact the service provider for availability of wireless connections
on the access point.
• Check SSID and security settings of the AP. Refer to the appropriate
documentation for SSID and security settings of the AP.
• Invalid settings of network devices (wired/wireless line sharer, hub) can cause
the projector to operate slowly or not operate properly. Install the devices
correctly according to the appropriate manual and network.

Tips for Using a USB storage device
• A USB storage device that has a built-in automatic recognition program or uses
its own driver might not be recognizable.
• Some USB storage devices may not be supported or may not work properly.
• If you use a USB extension cable, the USB storage device may not be recognized
or may not work properly.
• Please use only USB storage devices formatted with the FAT32 or NTFS file
system provided by Windows OS.
• It is recommended that you use an external USB HDD with a rated voltage of 5
V or less and a rated current of 500 mA or less.
• It is recommended that you use a USB hub or hard disk drive with a power
supply. (If the power supplied is not sufficient, the USB storage device may not
be detected properly.)
• It is recommended that you use a USB stick of 32 GB or less or a USB HDD of 2
TB or less.
• If a USB HDD with power-saving function does not work, turn the hard drive off
and on again to make it work properly. See the owner’s manual for the USB HDD

conversion cable / RS-232C input (control & service) / HDBaseT input (control &
service) terminal.
You have several ways to connect the projector depending on the supported
terminals of the model.
• Not all models support the USB-to-serial conversion cable connection.
• RS-232C cable and USB-to-Serial converter cable is not provided.
• The configurable items differ depending upon model.

(PC) (Projector)
• LG Projector supports PL2303 chip-based (Vendor ID: 0x0557, Product ID:
0x2008) USB to serial(RS-232C) converter which is not made nor provided by
LG.
• It can be purchased from computer stores that carry accessories for IT support
professionals.
• When the USB-serial conversion cable is connected, you cannot control the

• (Command 1): k, j, m, x
• (Command 2): This command is used to control the projector.
• (Set ID): Use this to select the projector to control, and the ID can be assigned to
each projector in [General] [About This Projector] [Set ID]. Select a value
ranging from 1 to 99. By selecting ‘0’ for the Set ID value in the protocol format,
you can control all connected projectors.
* The value is displayed as base 10 on the OSD menu and used as base 16
(0x00 - 0x63) in the transmission/reception protocol for remote control.
• (DATA): Transmits a setting value (Data) required for the command described
previously. (hexadecimal) When the Data ‘FF’ is sent, the setting value
corresponding to the specific command is read (Data read mode).
• (Cr): Carriage return, which is ‘0x0D’ in ASCII code.
• ( ): Space, which is ‘0x20’ in ASCII code.
