Setup
1 . Determine which source will be used for the EDID
information and configure the DDC switches appropriately
(see pages 3-2 to 3-5). If necessary, use the EDID Minder to
read and store information from a display (see pages 3-2 to
3-3).
2 . Prepare twisted pair cables (see "Terminating shielded
cable" on page 2-14).
3 . Connect the transmitter to the receiver (see "Connections"
on page 2-15)
4 . Connect the source device to the transmitter (see "DVI-D
input" on page 2-12). Do not power on the source device at
this time.
5 . Connect the display device to the receiver (see "DVI-D
output" on page 2-12). If required, connect a local monitor
to the transmitter.
6 . If required, connect any RS-232 or IR control devices (see
"Control pass-through" on pages 2-18 to 2-19).
7 . Connect the power supply to the transmitter (see "Power
input" on page 2-20).
8 . Power on the display device.
9 . Power on and boot up the source device.
Troubleshooting
If the DVI DL 201 Tx/Rx does not provide a high quality output
signal, check the following possibilities before contacting
your Extron representative (see the back cover for contact
information). Be sure to read all the suggestions as many of the
issues have several possible solutions.
No output signal —
Check that the front panel LEDs for both
the transmitter and receiver are on (lit amber). If they are not,
check the power supply connections to the units.
If a single power supply is being used to power both units, it
must be connected to the transmitter.
N Do not try to power both units with a single power
supply connected to the receiver as that will not provide
adequate power to the transmitter.
There are some circumstances, particularly with longer
Unsheilded Twisted Pair (UTP) cable runs, where the receiver
may not get adequate power. Under these circumstances, it may
be necessary to use two separate power supplies, one for the
transmitter and one for the receiver.
