Connecting Multiple Projectors - Christie Roadie HD+35K User Manual

Section 2: Installation and Setup
Ethernet Communications
To add the projector to an existing Ethernet network with other
equipment such as controllers and other projectors, connect
standard CAT5 Ethernet cable between your Ethernet controller (or
hub) and the Ethernet port on the side of the projector.
NOTE:
An Ethernet crossover cable is required when connecting
directly to a PC only.
Upon connection to an Ethernet network, the projector's factory
default IP address of 0.0.0.0 automatically enables the DHCP server
function (if a DHCP server is available on the network). For
example, the projector obtains a new IP address that is valid and
unique for that network from the DHCP server. Or, if there is no
DHCP server present (or if a specific static IP address for the
projector is preferred or required), you can set the address in the
Ethernet Settings
NOTE:
Ensure that the projector is connected to the network before
attempting to change its IP address.
Regardless of how it is assigned, once a projector has a valid and
unique address, it responds to commands sent to this address after
the next power-up. To determine the projector's current IP address,

Refer to Section 3.7 Adjusting System Parameters and Advanced
Controls for further information about setting up and using a
projector connected via Ethernet.
The GPIO Port
The General Purpose In-Out (GPIO) port enables integration of the
projector within an established control system so that other devices
connected via the GPIO can operate in tandem with the projector, or
vice versa. ASCII commands sent via standard serial ports can be
stored in projector memory, where they can then trigger a sequence
of events in response to incoming or outgoing signals at the GPIO
port, depending on your programming of the GPIO pins. For
example, you can automatically dim the room lighting when the
projector is turned on, or automatically turn the projector off when
the lights are raised.
IMPORTANT! Use a serial cable that is compatible with the external device.

Connecting Multiple Projectors

You may wish to link two or more projectors together so that commands and communications to and from a
controller are relayed between projectors. Choose a hardware configuration that best suits your desired
communication method.
