Optional Rack Mount Kit
The Distribution Amplifiers can be mounted in a standard 19” equipment rack. To
mount either the 1T-DA-654 or 1T-DA-664 in a rack, the optional RM-220 Rack Mount
kit must be purchased. Using this kit, either model can be mounted in the rack. A blank
panel is provided when only unit is mounted in the frame. It’s also possible to mount one
of each model or two of the same model in the frame. To mount the 1T-DA-658 in a
rack, the optional RM-380S Rack Ears must be purchased. Attach these to the sides of
the unit for installation into a 19” rack.

OPERATING THE HDMI DISTRIBUTION AMPLIFIERS
Once the input, output and power cables are connected, plug the AC adaptor into the
wall 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 display’s EDID and
record the value in the DA. If the first detected output display is DVI, it will pass to next
display 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
HDMI 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.
