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 ADM-188 AES Audio Delay. The ADM-188 is part of a full line of modular conversion gear for broadcast TV environments.
Supported Audio Formats Discrete AES Audio Input The ADM-188 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. Sample rate conversion is employed to account for minor clock rate differences in the AES stream and the input video stream. However, the card does not support AES input at 32 kHz, 44.1 kHz, 96 kHz or 192 kHz rates.
Functional Block Diagram This section describes the basic operation of your ADM-188 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 ADM-188 Block Diagram Figure 1. Simplified Block Diagram of ADM-188 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 • Card Control and Settings • Factory Default Settings 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-ADM-188-B or RM-ADM-188-C. You will need to install it in your 8310 frame before you can connect cables. Use the following steps to install a rear module in an 8310 openGearTM frame: 1.

Board Installation Use the following steps to install the card in the openGearTM 8310 frame: 1. Warning Refer to the Owner’s Manual of the openGearTM 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), these LEDs correspond to AES Inputs 1-4. The four orange LEDs labeled User 1-4 correspond to AES Inputs 5-8 respectively. When the card has locked to an AES signal, a corresponding LED will be illuminated. When the card has not locked to an AES signal, the card will search for a signal and the lights will cycle rapidly.
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. Software Build Number A read only indication of the software build number.
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 (www.sierravideo.com). Using the Menus and Menu Descriptions You must first install the DashBoard Control System software on your computer.
Menu Item Source (per channel) AES Audio Out 1/2 - 7/8 Gain (per channel) Format Description AES 1-16 Silence Selects the source for the AES outputs. Each AES source can be chosen separately. Range (-400) - 400 Gain applied to AES audio output. Tone Generator 1-4 Inverts the phase of the AES audio output. Phase Normal (per channel) Invert Menu Item Format Description Tone Generator Tone Generator 1-4 Frequency Range 50Hz –16KHz Selects the frequency of the tone generated.
