Enabling Security [SECURITY]
This feature turns on or off the SECURITY function.
Unless the correct keyword is entered, the projector cannot project an image. (→ page 30)
NOTE: Your setting will not be affected even when [RESET] is done from the menu.
Selecting Communication Speed [COMMUNICATION SPEED]
This feature sets the baud rate of the PC Control port (D-Sub 9P). It supports data rates from 4800 to 38400 bps. The
default is 38400 bps. Select the appropriate baud rate for your equipment to be connected (depending on the equip-
ment, a lower baud rate may be recommended for long cable runs).
NOTE: Your selected communication speed will not be affected even when [RESET] is done from the menu.
Selecting the serial port [SERIAL PORT]
This sets which terminal on the projector will receive the serial control signals for remotely controlling the projector
from a commercially available HDBaseT transmission devices (control signals for turning the power on and off, etc.).
There is no need to make this setting if not operating the projector by remote control (only sending video and audio).
PC CONTROL ��������� Control signals (RS232C serial communications) are received at the PC CONTROL terminal�
HDBaseT ���������������� The video/audio and control signals (RS232C serial communications) are received at the Ethernet/HDBaseT
port�
NOTE:
• When [HDBaseT] is set, it will not work when the projector is in the standby mode, regardless of whether [STANDBY MODE] (→
page 61) is set to [NORMAL] or [NETWORK STANDBY] (the power cannot be turned on).
The methods below can be used to turn on the projector's power when it is in the standby mode.
• The projector can be operated by connecting the computer and projector by RS232C serial communications (on the projector,
using the PC CONTROL terminal and the PC Control Utility application, with [STANDBY MODE] set to [NETWORK STANDBY]).
• The projector can be operated by connecting the computer and projector over the network (on the projector, using the LAN
port and PC Control Utility application, with [STANDBY MODE] set to [NETWORK STANDBY]).
TIP:
• When controlling the projector using the LAN port, this works with either setting.
Turning On or Off Remote Sensor [REMOTE SENSOR]
Set the remote control sensors on the projector's front and rear panels and the HDBaseT remote control sensor.
The options are: ALL, FRONT/BACK, FRONT, BACK, and HDBaseT.
NOTE:
• When [HDBaseT] is set, it will not work when the projector is in the standby mode, regardless of whether [STANDBY MODE] (→
page 61) is set to [NORMAL] or [NETWORK STANDBY] (the power cannot be turned on).
TIP:
• If the remote control system does not function when direct sunlight or strong illumination strikes the remote control sensor of
the projector, change another option.
• Remote control by infrared rays is not available when the remote control cable is connected to the REMOTE termial.
