Connecting example using DIGITAL LINK
Twisted-pair-cable transmitters based on the communication standard HDBaseT
TM
such as the optional DIGITAL
LINK output supported device (Model No.: ET-YFB100G, ET-YFB200G) use the twisted pair cable to transmit
input images, Ethernet, and serial control signal, and the projector can input such digital signal to the <DIGITAL
LINK> terminal.
*1
Control target is the projector or the twisted-pair-cable transmitter. The control itself may not be possible depending on the twisted-pair-cable
transmitter. Check the operating instructions of the device to be connected.
Attention
f
Always use one of the following when connecting a VCR.
g
Use a VCR with built-in time base corrector (TBC).
g
Use a time base corrector (TBC) between the projector and the VCR.
f
The image may be disrupted when nonstandard burst signal is connected. In such a case, connect the time base corrector (TBC) between
the projector and the external devices.
f
Ask a qualified technician or your dealer to install the cable wiring between the twisted-pair-cable transmitter and the projector. Image may
be disrupted if cable transmission characteristics cannot be obtained due to inadequate installation.
f
For the LAN cable between the twisted-pair-cable transmitter and the projector, use a cable that meets the following criteria:
g
Conforming to CAT5e or higher standards
g
Shielded type (including connectors)
g
Straight-through
g
Single wire
g
Diameter of the cable core is same or larger than AWG24 (AWG24, AWG23, etc.)
f
When laying cables between the twisted-pair-cable transmitter and the projector, confirm that cable characteristics are compatible with
CAT5e or higher using tools such as a cable tester or cable analyzer.
When a relay connector is used, include it in the measurement.
f
Do not use a switching hub between the twisted-pair-cable transmitter and the projector.
f
When connecting to the projector using a twisted-pair-cable transmitter (receiver) of other manufacturers, do not place another twisted-pair-
cable transmitter between the twisted-pair-cable transmitter of other manufacturers and the projector. This may cause image to be disrupted.
f
To transmit the Ethernet and serial control signals using the <DIGITAL LINK> terminal, set the [NETWORK] menu
→
[ETHERNET TYPE] to
[DIGITAL LINK] or [LAN & DIGITAL LINK].
f
To transmit the Ethernet signal using the <LAN> terminal, set the [NETWORK] menu
→
[ETHERNET TYPE] to [LAN] or [LAN & DIGITAL LINK].
f
The <DIGITAL LINK> terminal and the <LAN> terminal are connected inside of the projector when the [NETWORK] menu
→
[ETHERNET
TYPE] is set to [LAN & DIGITAL LINK]. Do not directly connect the <DIGITAL LINK> terminal and the <LAN> terminal using a LAN cable.
Construct the system so that it is not connected to the same network via the peripherals such as the switching hub or the twisted-pair-cable
transmitter.
f
Do not pull cables forcefully. Also, do not bend or fold cables unnecessarily.
f
To reduce the effects of noise as much as possible, stretch out the cables between the twisted-pair-cable transmitter and the projector
without any loops.
f
Lay the cables between the twisted-pair-cable transmitter and the projector away from other cables, particularly power cables.
f
When laying multiple cables, run them side by side along the shortest distance possible without bundling them together.
f
After laying the cables, go to the [NETWORK] menu
→
[DIGITAL LINK]
→
[DIGITAL LINK STATUS] and confirm that the value of [SIGNAL
QUALITY] is displayed in green which indicates normal quality. (
