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 9301 AES Audio Delay. The CDI-9301 is part of a full line of modular conversion gear for broadcast TV environments. The Cobalt Digital openGear line includes video decoders and encoders, audio embeders and de-embeders, distribution amplifiers, format converters, and much more.
All card configuration is done with a simple front panel menu. There is a four character text display to view and control parameters, and a toggle switch and two buttons to navigate the menu. Supported Audio Formats Discrete AES Audio Input The 9301 can accept 16 channels (8 pairs) of discrete AES audio on 75 ohm BNC connections. The AES must have a nominal rate of approximately 48 kHz.
Functional Block Diagram This section describes the basic operation of your 9301 product. Audio Control: 8 pairs 16 channels AES Decode and Sample Rate Conversion Routing Gain Polarity Audio Delay (5.461 Seconds Max) AES Encode 8 pairs 16 channels 9301 Block Diagram Figure 1. Simplified Block Diagram of 9301 Functions AES signals are received on the input BNCs. AES audio is sample rate converted to match the selected clock source. AES routing, gain, and polarity are then applied.
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 a rear module with the card. The 9301 can be ordered with an RM-9301-A, RM-9301-B, or RM-9301-C with your card. 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.
Using the Cobalt 1858-rm doublewide rear I/O module gives access to all 8 AES inputs and all 8 AES output BNC’s (2 channels per BNC). Figure 4. BNC Designations for Rear IO Module 1858-RM NOTE: If using the 1858 rear module, switches S11-S14 must all be switched to IN. Page 12 of 20 CDI-9323 User Manual • (V 0.
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.
