■ Preparation
● Mount the supplied wireless LAN PC card into the projector, and select
PC card input
Referring to “Mounting a PC card,”
p.23
mount the supplied wireless LAN PC card, then
select PC card input in accordance with “Select input”
p.27
.
● Projector settings
The factory settings can be used as-is. If necessary, conduct the following settings,
referring to “How to use the menu”
p.52
and “The PC card setting menu”
p.54
.
• [Communication mode]:
Your projector is set to Ad-Hoc in the factory. See “How to Use the Projector
Configuration Tool”
p.59
if you would like to set the mode to Infrastructure. This
menu item is used only for channel confirmation and the mode change from
Infrastructure to Ad-Hoc.
• [Channel]
This item cannot be changed currently. This is function for the future.
• [Encryption]
Set the security encryption level. The higher the number of bits, the stronger the
encryption, and hence the harder it will be for a third party to decipher your
communications. However, setting higher encryption levels will slow down
communication speed.
• [Key]
The key must be set for any encryption setting other than None. [64-bit] sets the key
length to 5 characters, [128-bit] to 13.
• [Projector name]
This can be used to identify projectors when communicating with multiple projectors, or
if there is a possibility that another person who is out of communication range will be
using the same projector. It is recommended this is set to prevent wrong transmission.
● Installing the applications
Install the applications on your computer, in accordance with “Installing the
applications”
p.24
.
● Computer settings
Refer to instruction manuals of your computer or wireless LAN PC card to perform the
following settings.
• Select Ad-Hoc (for some PC cards, this is Peer-to-Peer Group).
• Set the Channel to channel assigned to the projector (in factory reset mode, this is set
to 10). (For some computers, you cannot set the channel in Ad-Hoc mode. For this
case, use infrastructure communication mode.)
• Set SSID (For some types of PC card, use Network Name instead) as the same as
projector’s SSID (at factory shipment, this is set to DPJ).
• If Encryption and Key are set on the projector, set to the same values.
