of products, backed by Sierra Video's experience in engineering and design expertise.
You will be pleased at how easily your new UDA-8705A fits into your overall working environment.
Equally pleasing is the product quality, reliability and functionality. Thank you for joining the group of
worldwide satisfied Sierra Video customers!
Should you have a question pertaining to the installation or operation of your UDA-8705A, please
contact us at the numbers listed on the back cover of this manual. Our technical support staff is always
available for consultation, training, or service.
Overview
The UDA-8705A is an analog general-purpose distribution amplifier. It is very useful in digital systems
when there is a requirement for the distribution of a few analog signals, such as a color black reference.
The UDA-8705A is a general-purpose amplifier for use in the distribution of analog SD-video, Tri-
level sync or AES3id audio. It is intended for use in situations where cable equalization and differential
input are not needed, and clamping is not required. Gain is adjustable over a wide range of ±3dB.
This amplifier is DC-coupled and will faithfully provide all aspects of a video input signal to eight
identical output copies with very low distortion. The use of new generation integrated circuits and
innovative engineering has resulted in excellent performance combined with economy.
The UDA-8705A is designed for use in the openGear DFR-8300 series frames.

Rear Module Installation (Optional)
The UDA-8705A is compatible with the DFR-8310 and DFR-8320 series frames. The procedure for
installing the Rear Module in your openGear frame is the same regardless of the frame or module used.
However, a different module is required depending on the openGear frame you are using.
Rear Modules for the UDA-8705A
The Rear Module for the UDA-8705A depends on the openGear frame you are installing the card into.
•DFR-8310 series frames — When installing the UDA-8705A in the DFR-8310 series
frames, the R1-8705 or R1L-8705 Rear Modules are required. The UDA-8705A is
also compatible with the DFR-8310-BNC frame.
•DFR-8320 series frames —When installing the UDA-8705A in the DFR-8320 series
frames, the Split Rear Module (R2S-8705) or Full Rear Modules (R2-8705 or R2L-
8705) are required.
Installing the Rear Module
If you received a Rear Module with your UDA-8705A, you will need to install the module in your
DFR-8300 series frame before you can install the UDA-8705A in the frame, or connect cables to the
slot you have chosen for the UDA-8705A. Skip this section if you are installing the UDA-8705A in a
DFR-8310-BNC frame, or the Rear Module is already installed.
Use the following procedure to install the Rear Module in a DFR-8300 series frame:
1. Refer to the DFR-8300 series frame User Manual, to ensure that the frame is properly
installed according to instructions.
2. On the rear of the frame, locate the card frame slot.
3. Remove the Blank Plate from the rear of the slot you have chosen for the UDA-
8705A installation. If there is no Blank Plate installed, proceed to the next step.
4. As shown in Figure 3, seat the bottom of the rear module in the seating slot at the
base of the frame’s back plane.
Figure 3. Rear Module Installation in a DFR-8310 Series Frame (UDA-8705A not shown)

UDA-8705A User Manual (Rev. 1.1) Installation and Setup •2-3
5. Align the top hole of the rear module with the screw hole on the top edge of the
frame back plane.
6. Using a Phillips driver and the supplied screw, fasten the rear module to the back
plane. Do not over tighten.
7. Ensure proper frame cooling and ventilation by having all rear frame slots covered
with Rear Module or blank metal plates. If you need blanks, refer to the chapter,
“Ordering Information” in your DFR-8300 series frame User Manual, and contact
your Sierra Video sales representative.
This completes the procedure for installing the Rear Module in a DFR-8300 series frame.
Board Installation
Use the following procedure to install the UDA-8705A in a DFR-8300 series frame:
1. Refer to the User Manual of your DFR-8300 series frame to ensure that the frame is
properly installed.
2. After selecting the desired frame installation slot, hold the UDA-8705A card by the
edges and carefully align the card edges with the slots in the frame.
3. Fully insert the card into the frame until the rear connection plugs are properly seated
on the midplane and rear modules.
This completes the procedure for installing the UDA-8705A in an DFR-8300 series frame.
BNC Labels
Affix the supplied BNC label, as per the included instructions, to the BNC area on the rear of the rack
frame.
Cable Connections
This section provides instructions for connecting cables to the installed Rear Modules on your DFR-
8300 series frame backplane.
Connections for the DFR-8310 Series Frames
In the DFR-8310 series frames, the UDA-8705A occupies one slot and provides eight analog outputs.
The input of the UDA-8705A can be terminated on the card depending on the rear module used. It is
not necessary to terminate unused outputs.
In the DFR-8310 series frames, the UDA-8705A may be used with the following Rear Modules:
•R1-8705 Full Rear Module — Each card provides eight outputs. The input must be
terminated on the UDA-8705A using JP1. Refer to Figure 4 for cable connections.
•R1L-8705 Full Rear Module — Each card provides eight outputs and one looping
output. If the input is looped on the rear module to another device, JP1 must be set
to LOOP. If looping is not used, either set JP1 to TERM, or terminate the input
externally at BNC 2. Refer to Figure 5 for cable connections.

In the DFR-8320 series frames, the UDA-8705A may be used with the following Rear Modules:
•R2-8705 Full Rear Module — Each card occupies two slots and provides eight
outputs. The input must be terminated on the card by setting JP1 to TERM. Refer to
Figure 4 for cable connections.
•R2L-8705 Full Rear Module with Looping — Each card occupies two slots and
provides eight outputs plus one looping output. If the input is looped on the rear
module to another device, JP1 must be set to LOOP. If looping is not used, either
set JP1 to TERM, or terminate the input externally at BNC2. Refer to Figure 5.
•R2S-8705 Split Rear Module — Each card occupies one slot and provides four
outputs. Note that each Rear Module provides connections for two cards. Ensure the
input is terminated on the card at JP1. Refer to Figure 6 for cable connections.

Jumper Locations
The following sections describe the jumpers on the UDA-8705A.
Figure 7. Jumper Locations
JP1 — Local Termination Jumper
The position of JP2 selects an optional 75ohm termination on the input of the UDA-8705A card.
Select one of the following options:
•TERM — Install the jumper in this position to terminate the input signal on this
card. This is the default setting.
•LOOP — Install the jumper in this position to leave the input unterminated. For
example, configure this setting if you wish to loop the signal to another device.
RV2 — Gain Adjustment
The rotation of RV2 adjusts the Gain level of the UDA-8705A and provides a gain range of +/- 3dB.
LEDs
The following sections describe the UDA-8705A LEDs. Refer to Figure 8for LED locations.

UDA-8705A User Manual (Rev. 1.1) User Controls •3-3
PWR (Power) LED
The PWR LED indicates the overall operating status of the UDA-8705A. This LED displays the
following conditions:
•Green — The card is operating normally.
•Flashing Green — The card requires a software upgrade.
•Red — The card is not operational. Refer to the chapter, “Service Information” for
details on this condition.
Input Signal Present LEDs
The Input Signal Present LEDs indicates the status of the analog input. This group of LEDs display
the following conditions:
•VIDEO — If the VIDEO LED is lit, a valid analog video input signal is present on
BNC 1.
•AES/OTHER — If the AES/OTHER LED is lit, a valid AES signal, or some other
analog signal, is present on the input. The signal must be greater than 0.5Vp-p.
Note Slowly changing, or small, amplitude signals will pass through the card, but the
LEDs may be unlit. In this case, it is recommended to disable the Notify on
Input Loss option via DashBoard. Note that the Input Signal Present threshold
is set to assume a level of 1Vp-p.
