Preparation
●
Mount the supplied wireless LAN PC card into the projector, and select
PC card input
Referring to “Mounting a PC card,”
mount the supplied wireless LAN PC card, then
select PC card input in accordance with “Select input”
.
●
Projector settings
The factory settings can be used as-is. If necessary, conduct the following settings,
referring to “How to use the menu”
and “The PC card setting menu”
.
• [Communication mode]:
Your projector is set to Ad-Hoc in the factory. See
“How to Use the Projector
Configuration Tool”
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”
.
●
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.
