OG-12G-AMA openGear Card v1.0 4 www.aja.com
Chapter 1 – Introduction
Card Overview
The OG-12G-AMA is an 8-channel analog audio embedder/disembedder Mini-
Converter. It supports 12G-SDI input and output up to 4K/UltraHD single link.
Analog audio can be embedded and disembedded simultaneously. Audio
embedding and disembedding is user selectable, on a channel pair basis, to
either pass SDI embedded audio or to embed input analog audio from the 3-pin
terminal block connectors. Analog audio operating levels are selectable, via
DashBoard software by Ross Video.
The ability to pass incoming ancillary data makes it possible to embed up to
16 channels of audio by cascading two units. Horizontal ancillary data (HANC)
packets in compliance with SMPTE 291M can also be passed through or removed
at the input.
The OG-12G-AMA automatically detects and configures to the input video
standard. 12G-SDI formats up to and including 4096x2160p 60 YCbCr 4:2:2 are
supported (see "Appendix A Specifications" on page 22 for a complete listing). SDI
video passes through the device with minimal delay. Pass through embedded SDI
audio supports up to 16 channels.
NOTE: 2048x1080p/PsF 29.97 and 30 formats support a maximum of 8 channels of
embedded audio.

Signal Indicators on the OG-12G-AMA Card
Located at the upper front area of the OG-12G-AMA card, the Lock LED indicates
by color the type of signal detected by the SDI input (Table 1).

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 input signal is not present, the DashBoard Control System shows a
yellow Card State alarm: "Signal Lock Not Locked." Additionally, under the Status
tab, the Signal Lock status is shown as "Not Locked," and the Input Signal is shown
as "No Video."
Figure 3. Signal not present or not locked
Card Alarm State – Green
When there is a valid input signal detected, the DashBoard Control System shows
a green Card State. Additionally, under the Status tab, the Signal Lock is shown as
"Locked," and the Input Signal field shows the resolution of the signal detected.

User Controls
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 12.

Installation
Summary
Installing an OG-12G-AMA card into an OG-X-FR openGear frame consists of the
following steps:
• Install the rear plate onto the back of the frame corresponding to the slot pair
you will be using for the OG-12G-AMA card.
• Insert the OG-12G-AMA card into the frame in the right (even numbered) slot
of the pair.
• Connect the BNC and audio cabling to the rear plate connectors.
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.
Unpacking
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.

OG-12G-AMA Rear Plate Installation
1. Ensure that the chassis is properly installed in a secure rackframe.
2. Locate the card frame slot on the rear of the openGear frame into which you
wish to install the openGear card.
NOTE: An OG-12G-AMA card occupies two slots in the frame.
3. Using a Phillips screwdriver, unscrew the top screw from the desired blank
rear plate and remove it.
4. Seat the bottom of the rear plate in the seating slot at the base of the frame
back plane (Figure 5).

Figure 5. Inserting Rear Plate Into Frame Seating Slot
5. Align the top screw of the rear plate with the screw hole on the top edge of
the frame back plane.
6. Ensure the rear plate aligns with the desired card slot before tightening the
screw.
7. Using a Phillips screwdriver, fasten the rear plate to the frame back plane
(Figure 6). Do not over tighten.
Figure 6. Rear Plate Inserted Into Frame Seating Slot
8. Ensure proper frame cooling and ventilation by having all rear frame slots
covered with either OG card rear plates or blank metal plates.
OG-12G-AMA Card Installation
1. Open the openGear frame door as follows:
A. Gently pull the side door tabs towards the center of the door, releasing the
door from the frame.
B. Using both hands, pull the door towards you. The door extender arms
prevent the door from falling.
2. Locate the rear plate you installed as described above. The interior slot
number is dependent on the slot combinations into which you installed the
rear plate. This allows adequate spacing to avoid damaging the card, the
cards installed in the neighboring slots, or both.

OG-12G-AMA openGear Card v1.0 10 www.aja.com
3. Hold the card by the edges and carefully align the card edges with the rails
inside the frame. The slots are numbered starting from the left-most slot
when facing the frame front.
IMPORTANT: OG-12G-AMA cards are installed into the right (even numbered) slot of the
pair in order to connect with the rear plate.
4. Insert the card into the frame until the card is properly seated in the Rear
Plate. After you feel the card's first click, its position in the frame will
resemble Figure 7.
Figure 7. Card on Right Not Fully Inserted
5. Next, press against the white plastic tab again until you feel the second
click. Make sure that the plastic tab at the bottom of the front edge of the
card is completely upright. If it is tilting forward, the card is not yet fully
inserted. A properly seated card position should resemble Figure 8.
Figure 8. Card Fully Inserted, White Plastic Tab Upright
6. Some OG cards require more pressure than others to be fully inserted. Do
not apply excessive force if you cannot completely insert the card into its
slot.
7. Close the frame door as follows:
