A Word of Thanks
Congratulations on choosing the openGearTM DAH-339 Triple 3G/HD/SD Reclocking Distribution
Amplifier. The DAH-339 is part of a full line of modular conversion gear for broadcast TV
environments. The Sierra Video openGearTM line includes video decoders and encoders, audio
embedders and de-embedders, distribution amplifiers, format converters, and much more. Sierra
openGearTM modular conversion gear will meet your signal conversion and distribution needs now and
well into the future.
Should you have questions pertaining to the installation or operation of your DAH-339, please contact
us at the numbers listed on the back cover of this manual. We are happy to help with any questions
regarding this or any other openGearTM card.
Overview
The DAH-339 is a high quality three channel 3G/HD/SD Reclocking Distribution Amplifier. It is
capable of equalizing and reclocking three channels in 3G, HD or SD.
The DAH-339 can equalize and reclock incoming SDI signals using up to 300m of cable at 270 Mbps,
up to 120m of cable at 1.485 Gbps, and up to 80m at 2.97Gbps.
One channel of ASI can be reclocked and output for each of the SDI inputs. The BNC’s that output a
non-inverted signal suitable for ASI are BNCs #4, 5, and 8.

Installation and Setup
ESD
Susceptibility
Static discharge can cause serious damage to sensitive
semiconductor devices. Avoid handling circuit boards in high
static environments such as carpeted areas, and when wearing
synthetic fiber clothing. Always exercise proper grounding
precautions when working on circuit boards and related
equipment.

Whenever handling the card and other related equipment, please observe all static discharge
precautions as described in the following note:
Unpacking
Unpack each card you received from the shipping container, and check the contents against the packing
list to ensure that all items are included. If any items are missing or damaged, contact your sales
representative or Sierra Video directly.

Rear Module Installation (Optional)
If you are installing the card in a 8310-C-BNC or 8310-BNC frame (one with a 100 BNC rear module
installed across the entire back plane), skip this section.
If you are installing the card into a slot with no rear module, you should have ordered and received a
DAH-339-A Rear Module with your card. You will need to install it in your 8310 frame before you can
connect cables.
Use the following steps to install the DAH-339-A in an 8310 openGearTM frame:
1. Refer to the openGearTM 8310 frame Owner’s Manual, to ensure that the frame is
properly installed according to instructions.
2. On the rear of the 8310, locate the card frame slot.
3. As shown in Figure 2, seat the bottom of the DAH-339-A in the seating slot at the
base of the frame’s back plane.
Figure 2. Rear Module Installation
4. Align the top hole of the DAH-339-A with the screw hole on the top edge of the 8310
back plane.
5. Using a Phillips driver and the supplied screw, fasten the DAH-339-A panel to the
8310 back plane. Do not over tighten.
This completes the procedure for installing the DAH-339-A in an 8310 openGearTM frame.

Board Installation
Warning
Heat and power distribution requirements within a frame may dictate
specific slot placement of cards. Cards with many heat-producing
components should be arranged to avoid areas of excess heat build-up,
particularly in frames using convection cooling.

Use the following steps to install the card in the openGearTM 8310 frame:
1. Refer to the Owner’s Manual of the openGearTM 8310 frame to ensure that the frame
is properly installed according to instructions.
2. After selecting the desired frame installation slot, hold the card by the edges and
carefully align the card edges with the slots in the frame. Then, 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 card in the openGearTM 8310 frame.
Cable Connections
This section provides instructions for connecting cables to the installed BNC rear modules on the 8310
series frame backplane. Connect the input and output cables according to the following diagram. The
input is internally terminated with 75 Ohms. It is not necessary to terminate unused outputs.

Card Status
The card has an LED that indicates whether Dashboard remote control is enabled, or if the switch bank
controls the card. See description of switch 1 below.
The card also indicates the status of each of the outputs signal with the three banks of four LEDs
labeled with the different supported formats (1080, 720, 625, 525). When the card has locked to a
particular output format, that LED will be illuminated. When the card has not locked to a particular
video format, the card will search all possible formats, and the lights will cycle rapidly.
Switches
There is a bank of eight switches (S1) on the front edge that controls the card.
* Switch 1 controls the behavior of the rest of the switches. With switch 1 set in the up position,
Dashboard remote control software can change the settings of the card. Consequently the rest of the
onboard switches will have no effect. With switch 1 set in the down position, Dashboard remote control
software is prevented from making changes to the card settings. Consequently the onboard switches 2-8
control the settings.
The factory default settings are as follows
1) Remote Control is enabled.
2) Reclocking on A, B, and C are set to On.

Remote Control
In This Chapter
This section provides a detailed explanation on using remote control functions with your card.
DashBoard Control System Software
The DashBoard Control System enables you to monitor and control openGearTM frames and controller
cards from a computer. The DashBoard software and manual can be downloaded from the Sierra Video
Systems website.
Using the Menus
You must first install the DashBoard Control System software on your computer. Refer to the
DashBoard User Manual for software installation procedures and for using the DashBoard interface.

Troubleshooting Checklist
Warranty and Repair Policy
Troubleshooting Checklist
Routine maintenance to this openGearTM product is not required. In the event of problems with your
card, the following basic troubleshooting checklist may help identify the source of the problem. If the
module still does not appear to be working properly after checking all possible causes, please contact
your openGearTM products distributor, or the Technical Support department at the numbers listed under
the “Contact Us” section at the end of this manual.
1. Visual Review Performing a quick visual check may reveal many problems, such
as connectors not properly seated or loose cables. Check the module, the frame, and
any associated peripheral equipment for signs of trouble.
2. Power Check Check the power indicator LED on the distribution frame front
panel for the presence of power. If the power LED is not illuminated, verify that the
power cable is connected to a power source and that power is available at the power
main. Confirm that the power supplies are fully seated in their slots. If the power
LED is still not illuminated, replace the power supply with one that is verified to
work.
3. Reseat the Card in the Frame Eject the card and reinsert it in the frame.
4. Check Control Settings Refer to the Installation and Operation sections of the
manual and verify all user-adjustable component settings.
5. Input Signal Status Verify that source equipment is operating correctly and that a
valid signal is being supplied.
6. Output Signal Path Verify that destination equipment is operating correctly and
receiving a valid signal.
7. Module Exchange Exchanging a suspect module with a module that is known to
be working correctly is an efficient method for localizing problems to indivitriple
modules.
