5.0 OPERATING THE DVI DISTRIBUTION AMPLIFIERS
Once the input, output and power cables are connected, plug the AC adaptor into the
AC receptacle and the Distribution Amplifier will begin to function. A Power LED on the
front of the unit will confirm power is present. Other than connecting cables and
applying power, there are no other operator interventions required with the possible
exception of the EDID jumper.
EDID Operation:
On the rear of the unit you’ll find an EDID* Jumper. This jumper controls whether the
DA determines the connected device’s EDID Number automatically or uses an internal
information table.
The default factory setting for the EDID Control Jumper is AUTO and you should leave
it as it is if the display is operating properly. Switch to INT (Internal) to use build-in
EDID information table should the display have problems. When the EDID control
jumper in AUTO position, the unit will detect the first HDMI output source’s EDID and
record the value in the DA. If the first detected output source is DVI, it will pass to the
next source in sequence until the first HDMI compliant device has been detected.
If the DA cannot reliably determine the destination device’s EDID number through the
handshake routine, switching to the internal table (INT) allows the DA to run through a
range of pre-defined resolutions and refresh rates so that a reliable connection can be
made.
* The Extended display identification data (EDID) is a data structure provided by a
computer display to describe its capabilities. It’s what enables the TV One OneTask DVI
DA to know what kind of monitor is connected to the unit. EDID is defined by a standard
published by the Video Electronics Standards Association (VESA). The EDID includes
manufacturer name, product type, phosphor or filter type, timings supported by the
display, display size, luminance data and (for digital displays only) pixel mapping data.
Operational LEDs
Besides the Power LED, there are status LEDs as well as other LEDS showing the
unit’s condition with respect to successfully executed output connections.
At the lower left, there are three LEDs which show signal format status. The first (or left-
most) LED shows whether an HDMI or DVI signal is being received. Next to that LED,
another LED shows if the signal is encoded with HDCP (High Definition Content
Protection) signals and a third LED shows if the signal has synchronized. There are also
LEDs for each output which show whether or not the output has successfully made a
connection with the destination device.
