the chain, so that only the last projector has one unused port RS-232 OUT, see Figure 2-22 Mixed Network.

Mixed Network

Communication parameters, such as baud rate, must be set to match the particular controlling device, before

connecting as a network—refer to the documentation that came with your controlling device to determine the proper

baud rate. See Section 3 Operation for help changing the projector baud rate. To communicate to all projectors, set

the Network Routing to “RS-232 and RS-422 Joined”.

NOTES:

1) Connect only properly wired serial communication cables.

2) Each RS-232 communication cable should be no more than 50 feet in length. Use high quality cables.

• Ethernet Network Setup

To add one or more projectors to an Ethernet network, use standard CAT5 cable to connect each projector’s

Ethernet port to a hub belonging to the network. A controller or PC must also be connected to the hub, see ﬁgure

below. NOTE: A wireless router can be used to communicate to the projectors via 802.11b/g.

Ethernet Network setup

• Setting the Projector’s IP address, subnet Mask and Gateway

You can refer to “Ethernet Settings”, page 66

Changing the port number#

On some Ethernet networks, ﬁrewall restrictions may 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#.

Separating Networks

By default, communications originating from one type of serial controller—RS-232 vs. RS-422 vs. Ethernet— stay

on the corresponding network path. A “Separate” setting indicates this separation for “Network Routing” in the

Communications menu, see “WEB USER INTERFACE”, page 75. If you are using an RS-422 controller, for

example, it will communicate only with the projector to which it is connected unless you change this setting to either

“RS-232 and RS-422 Joined” or “All Joined”.

• Communicating to all Ports

To relay all messages to all ports—RS-232, RS-422, and Ethernet—set the “Network Routing” option in the

Communications menu for each projector to “All Joined”, see “WEB USER INTERFACE”, page 75. This

conﬁguration is useful if you are using a non-RS-232 controller with the RS-232 linking available between these

projectors. For example, you may want to use both an RS-422-compatible controller and an Ethernet connected PC

for working with a network of projectors linked via their RS-232 in/out ports.

To isolate just RS-422 communications, select “RS-232 and Ethernet Joined”.
