Introduction In This Chapter This chapter includes the following sections: • A Word of Thanks • Overview • Functional Block Diagram • Features • Documentation Terms A Word of Thanks Congratulations on choosing the openGear 9323 HD/SD Audio Embedder/De-embedder. The 9323 is part of a full line of modular conversion gear for broadcast TV environments.
Audio rates are always 48kHz nominally but discrete AES inputs pass through sample rate converters to align them with the output timing. Output AES is always precisely locked in time with the output video. Analog audio is differential input and sampled at 48 kHz with 0 dbFS digital equivalent to +24 dBu analog. Dolby decoding is available from embedded audio or external AES, with the purchase of the Dolby decoding option.

Analog Audio A/D 8 pairs 16 channels AES Decode and SRC From AES or Embedded Audio Dolby E Decode and SRC Routing Gain Polarity Audio Embed AES Encode Serializer and Cable Driver 8 pairs 16 channels CDI-9323 Block Diagram Figure 1.
Embedded Audio The 9323 supports all four groups (16 channels) of embedded audio at full 24 bit resolution in both SD (with extended data packets) and HD. Analog Audio The 9323 supports 8 channels differential analog audio. The analog audio is encoded in such a way as to make +24 dBu (analog) equivalent to 0 dBFS (digital). Analog audio conversion can be disabled to reduce power consumption. Discrete AES Audio Input The 9323 can accept 16 channels (8 pairs) of discrete AES audio on 75 ohm BNC connections.
Low latency AES Passthrough This control is similar to zero delay audio embedding. If selected for input pair X it causes AES output pair X to act as a bit for bit copy of AES input pair X. This over rides the normal audio routing and delay. No gain and polarity adjustments are possible. This control is off by default. Documentation Terms The following terms are used throughout this guide: Page 10 of 28 • “Frame” refers to the 8310 frame that houses the 9323 card.
Installation and Setup In This Chapter This chapter includes the following sections: • Static Discharge • Unpacking • Rear Module Installation (Optional) • Board Installation • BNC Connections • Menu Structure • Factory Defaults Static Discharge Whenever handling the card and other related equipment, please observe all static discharge precautions as described in the following note: Static discharge can cause serious damage to sensitive semiconductor devices.
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 one of the following modules; RM-9323-A, RM-9323-B, RM-9323-C, RM-9323-D, RM-9323-E, RM9323-F, or RM-9323-G. You will need to install it in your 8310 frame before you can connect cables.

Board Installation Use the following steps to install the card in the openGear 8310 frame: 1. Warning Refer to the User Manual of the openGear 8310 frame to ensure that the frame is properly installed according to instructions. 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. 2.
Card Control and Status Card Status The card indicates the status of the input signal with the four blue LEDs labled with the different supported formats (1080, 720, 625, 525). When the card has locked to a particular input 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. Menu Navigation The card can be configured from a menu system built in to the front card edge.
Proc Phase This is Chroma (C channel) phase adjustment, expressed in degrees, ranging from –360 to +360 in steps of one degree.
Output Polarity If set to “Norm” output polarity is the same as input polarity, if set to “Inv” the output polarity is inverted. This can be used to correct polarity errors in the input signals fed to the card. Tone Frequency This sets the frequency of the test tone for each of the four tone generators. Each of the four tone generators TG1 – TG4 can be set to a different frequency, and are available as audio sources for the embedded or AES audio outputs. The tones can range from 50Hz to 16kHz.

Negative Watts Consumed A read only indication of power consumed by the card from the frames +-7.5V rail. Software Release Number A read only indication of the software release number. A higher number is newer release of software.
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 Cobalt Digital Inc. website. Using the Menus You must first install the DashBoard Control System software on your computer.
