OG-3GDA Series openGear Cards v1.2 3 www.aja.com
Chapter 1 – Introduction
Card Overview
AJA’s OG-3GDA Series cards are state-of-the-art, openGear-compatible, 3G-SDI
distribution amplifiers.
Features
• openGear compatible card (requires 2 slots, rear card included)
• Use with openGear 2RU frames
• Controlled by DashBoard network control software
• Automatic detection and re-clocking of 270Mb, 1.5Gb, and 3Gb SDI data rates
• Excellent input jitter tolerance and low jitter re-clocked outputs
• Input Present and Input SMPTE Lock LEDs (OG-3GDA-1x9)
• Input Present LEDs (OG-3GDA-2x4)
• Hot-swap capable
• 5 year warranty
OG-3GDA-1x9
For the OG-3GDA-1x9, the incoming SD, HD or 3G signal is distributed to each
of the nine 3G-SDI outputs, allowing the same signal to be sent to multiple
destinations simultaneously.
If the incoming SD, HD or 3G signal is one of the five SMPTE rates (270 Mbps, 1.483
Gbps, 1.485 Gbps, 2.966 Gbps, 2.970 Gbps), the signal will be reclocked, and both
the SMPTE Lock LED and Signal Present LED will illuminate. Otherwise, if a nonSMPTE input is detected, the signal will bypass the reclocker and only the Signal
Present LED will illuminate.
OG-3GDA Series openGear Cards v1.2 4 www.aja.com
OG-3GDA-2x4
The OG-3GDA-2x4 offers two modes: Dual 1x4 or Single 1x8. In either mode, the
OG-3GDA-2x4 allows the same signal or signals to be sent to multiple destinations
simultaneously.
The incoming SD, HD or 3G signal(s) will be reclocked if it is one of the five SMPTE
rates (270 Mbps, 1.483 Gbps, 1.485 Gbps, 2.966 Gbps, 2.970 Gbps). Otherwise the
signal(s) will bypass the reclocker and be present at the outputs.
When a SD, HD, or 3G signal is detected, regardless of its compliance to SMPTE
standards, the Signal Present 1 and/or Signal Present 2 LEDs will illuminate,
depending on where the signal input is detected.
Dual 1x4 Mode
In Dual 1x4 Mode, the incoming SD, HD or 3G signals coming in through SDI Input
1 and SDI Input 2 are distributed to the two corresponding sets of four 3G-SDI
outputs. The two DAs are completely independent.
Single 1x8 Mode
In Single 1x8 Mode, the SD, HD or 3G signal coming in through SDI Input 1 is
distributed to the eight 3G-SDI outputs. Both Signal Present LEDs will illuminate
when a signal is present on SDI in 1.
LED Indicators
For OG-3GDA-1x9
LEDs on the front (near door) of each card indicate, from top to bottom:
• DC power detected (green)
• Input signal present (green)
• Input reclocker locked (green)
For OG-3GDA-2x4
LEDs on the front (near door) of each card indicate, from top to bottom:
• DC power detected (green)
• Input 1 signal present (green)
• Input 2 signal present (green)

* Non Inverting Outputs
Inverted and Non-Inverted Outputs
Five of the outputs (1, 3, 4, 7, 9) are non-inverting. These are suitable for levelsensitive signaling, such as DVB-ASI. The other four outputs (2, 5, 6, 8) are
identical, except inverted. All outputs are fully SDI compatible.

Signal Indicators in the DashBoard Control System
Card Alarm State – Red
This potential card state will result in a red alarm indicator:
• HW Status Unsupported Rear Module
Card Alarm State – Yellow
When the signal is either not present or is not locked, the DashBoard Control
System shows a yellow Card State alarm: "Signal Status No Signal." Additionally,
under the Input Status tab, the Signal Status is shown as "No Signal," and the
Input Lock is shown as "No Lock."
Figure 7. Signal not present or not locked
OG-3GDA Series openGear Cards v1.2 9 www.aja.com
Card Alarm State – Green
When there is a valid input signal detected, the DashBoard Control System shows
a green Card State. Additionally, under the Input Status tab, the Signal Status is
shown as "Signal Present," and the Input Lock is shown as "Locked." The detected
Data Rate of the SDI Signal is also indicated (for example, "1.5 Gbps").
Figure 8. Signal is present and locked
User Controls
The OG-3GDA Series cards can be used right out of the box for many applications,
since they are designed to recognize inputs and perform standard actions
automatically. However, you can also remotely monitor the OG-3GDA Series
through the DashBoard Control System for an openGear Frame.
OG-3GDA Series openGear Cards v1.2 10 www.aja.com
DashBoard Control System
The DashBoard Control System, created by Ross Video, provides a control
interface between Windows, macOS and Linux computers and the cards installed
in an openGear frame. DashBoard operates through TCP/IP communication
and requires an Ethernet connection between the controlling computer and an
openGear frame.
For details about acquiring and using the DashBoard Control System, refer to
"Using the DashBoard Control System" on page 15.
openGear and AJA
openGear is an open-architecture, modular frame system designed by Ross
Video and supported by a diverse range of terminal equipment manufacturers,
including AJA. Ross Video manufactures the frames, power supplies and network
cards for openGear. AJA is a reseller of the openGear frames.
AJA Video is a leading manufacturer of video interface technologies, converters,
digital video recording solutions and professional cameras, bringing highquality, cost-effective products to the professional, broadcast and postproduction markets. AJA products, including openGear cards, are designed and
manufactured at our facilities in Grass Valley, California.
Installation
Summary
Unpacking
Installing an OG-3GDA Series card into an OG-X-FR openGear frame consists of
the following steps:
• Install the Rear Panel onto the back of the frame corresponding to the slot pair
you will be using for the OG-3GDA Series card.
• Insert the OG-3GDA Series card into the frame in the right (even numbered)
slot of the pair.
• Connect the BNC cabling to the Rear Panel.
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.
Unpack each openGear product you received from the shipping container and
ensure that all items are included. If any items are missing or damaged, contact
your sales representative or AJA directly.
