Section 1: Introduction
5. When a new address is implemented in the projector, another dialogue box will remind you that if your
settings moved the projector to a different network (most common), the TPC will no longer be able to
control the projector. Ignore any Cancel buttons that may appear in this dialogue box. You must therefore
immediately change the TPC Ethernet configuration if you have changed either or both of the following:
• Any of the first 3 octets of the IP Address (i.e., the network node)
• The Subnet Mask
Be sure to change the TPC address before re-booting the projector. Warning! For both devices-projector
and TPC-the Subnet Mask and the first 3 octets of their IP addresses must match, otherwise the devices are
on different networks and cannot communicate. Do not re-boot until this match is confirmed.
You do not have to change the TPC Ethernet configuration if you have changed only the last octet of the
projector's IP Address. In this case (rare), both devices still belong to same network and will be able to
communicate with each other.
6. Change the TPC Ethernet network configuration (below).
HOW TO CHANGE YOUR TPC'S IP ADDRESS:
Select TPC at the top of the IP Config menu, then change the TPC's IP address in the same manner as you
changed the projector's address. Warning! The first 3 octets of the IP address must match those for the
projector. See Steps 2 and 3, above.
NOTE: This is the simplified explanation of valid addressing. A trained network administrator may expand the
range of valid addresses.
To implement the address changes in your projector and TPC, re-boot.
Important! Do not forget to re-boot the projector.
