[About IP address]
Network address of PC IP address should be common with projector's one but the
PC total IP address should not be overlapped with other networked equipments.
For example, projector initial settings are as follows.
Therefore, specify PC IP address as follows.
Select from 1 to 254 for "xxx" not duplicating with any other equipments. In this
case, projector has "192.168.1.10" IP address, specify from 1 to 254 except 10 for
PC.
Projector IP address can be changed by using configuration utility. (19)
* "0.0.0.0" cannot be set to IP address.
When DHCP server exists in network, it is possible to set using IP address, which
is automatically assigned to projector.
If projector and PC exist in the same network (i.e. network address is common),
default gateway can be blank.
* DHCP is abbreviation for "Dynamic Host Configuration Protocol" and the function
to provide necessary setting for network like IP address from server to client.
Server that has DHCP function is called DHCP server.
* When projector and PC exist in different networks, default gateway setting is
necessary. Contact network administrator in detail.
