Separating or Joining
Serial Networks
one to the projector via a serial command. The projector will respond to commands
sent to this address after the next power-up, after which the IP address will remain in
projector memory until you enter a new one, or until the DHCP checkbox is re-
enabled.
NOTES: Only the port and IP address of the projector can be changed. The subnet
mask is fixed (255.255.255.0).
CHANGING THE PORT#:
require that the port number of the projector be changed from its default of 3002. If
so, enter a new port number in the Ethernet Settings menu or include the new port# in
an XIP serial command sent to the projector.

NOTES: 1) A separate "redundant" network requires double serial links—RS232
and RS422—between all projectors. 2) Set each projector's Broadcast Key to OFF.
3) Keypads cannot broadcast when networks are separate—use controller(s) instead.
4) Do not use a split network when downloading new projector software.
By default, communications originating from one type of serial controller—RS232
vs. RS422—stay on the corresponding network path rather than being broadcast to
the other network. This separation is sometimes known as a split network and is
indicated by a "Separate" setting for "Network Routing" in the Communications
menu (see Figure 2.37).
Figure 2.37. Keeping Networks Separate (default)
Keeping networks separate maximizes the efficiency of data transmission. In
addition, separate paths means that one path can be considered a redundant "back-
up", available if a failed projector (or controller) prevents communication via the first
path. With a split network, each projector receives and sends either type of message
depending on which controller initiates the commands—should one path fail, the
second "back-up" network path can be used. Only one network should be active at a
given time, as determined by the controller type, i.e., whether it is RS232 or RS422.
Note that the "Broadcast Key" option must be OFF.
Two Different Serial "Splits"
There are two different split serial network configurations possible (see Figure 2.38).
Set up whichever option best suits your application needs:
A.
SPLIT NETWORK WITH ONE CONTROLLER –

one physical end of the network and the other controller standard (e.g.,
