Page 5: Description
SNMP management and the ability to record events in a file including date and time information for further analysis. The AEM3000C01 is a TL3000 terminal line module and can be housed in a three rack unit (3 RU) UR3000 mounting frame or a 1 RU UR3100 mounting frame. -
Page 6: Features
• Module control and supervision can be done remotely when the mounting frame is equipped with a communications controller module. • One UR3000 mounting frame can house up to 12 AEM3000C01 modules. If power supply redundancy is required and FA3000 or FA3001 modules are used then only 10 modules can be housed in the mounting frame. -

Page 11: Installation
ELECTROSTATIC DISCHARGE. Always use antistatic bags clearly identified with a high degree of shielding for storage and transportation. The AEM3000C01 module is composed of two parts: one AEM3000P01 main board and one AEM3000P02 rear board. Both parts must be installed in a UR3000 or UR3100 mounting frame following the instructions in the corresponding section of this chapter. -

15 and 28 dBu in 1 dB steps. The AEM3000C01 comes from the factory programmed with full scale values of 22 dBu. The AEM3000C01 also includes a block of DIP switches for selection of the desired operating mode upon startup. -
Page 13: Installing The Module In The Mounting Frame
Indifferent 3.6. Installing the module in the mounting frame The steps needed to install the AEM3000C01 module with the rear board in the mounting frame are: 1 - Disconnect all power cords from the power supplies of the mounting frame. - Page 14 INSTALLATION section of this manual. 6 - Insert the AEM3000P01 board (main board of the AEM3000C01 module) into the front of the mounting frame. The edges of the card slide into two plastic guides inside the mounting frame.

Albalá Ingenieros | Manual AEM3000C01 3.7. Interconnection The following figure shows the AEM3000C01 module rear board connector layout. Rear view of the AEM3000C01 The module provides of SDI digital video input (IN) and two outputs (OUT1, OUT2). It also includes four inputs for analog audio (STREAM 1A, STREAM 1B, STREAM 2A and STREAM 2B). -
Page 16: Analog Audio Connections
All coaxial cable used must be Belden 8281 or similar. This type provides the greatest lengths because it is used to calculate the equalizers in the AEM3000C01. Cables carrying signal between the module and the devices should use single piece construction, avoiding spliced sections with double BNC female or barrel connectors. -
Page 17: Operation
Albalá Ingenieros | Manual AEM3000C01 4. OPERATION This section describes the significance of the front panel indicators of the AEM3000C01 module and their remote control and monitoring ability. 4.1. Front panel description The appearance of the front panel and the elements it contains are shown in the following illustration. -
Page 18: Configuration From The Front Panel
Selection of the group to be embedded is done via the front panel pushbutton or can be done with a computer when a communications controller module is installed in the same mounting frame as the AEM3000C01. The pushbutton operates in the following manner: 1.- Press and hold the button for more than one second to select the group. -
Page 19: The Pre-Processing Block
AEM3000C01 4.3. The pre-processing block The AEM3000C01 includes an audio pre-processing block that operates in the digital domain, prior to the A/D conversion. This block provides level adjustment, phase inversion and a small selection matrix between the four inputs and four outputs. The following figure explains the contents of this block along with their default configuration upon leaving the factory. -
Page 20: Module Remote Control And Supervision
Albalá Ingenieros | Manual AEM3000C01 4.4. Module remote control and supervision The AEM3000C01 can optionally be remotely controlled/supervised. In order to perform remote configuration and supervision of the module an optional TL3000 family remote communications controller must be installed in the mounting frame. -

Page 25: Glossary
Albalá Ingenieros | Manual AEM3000C01 5. GLOSSARY AES/EBU This acronym covers the combined AES and EBU standard for transmission of digital audio. The standard defines a serial interface known as AES3 as per AES, EBU 3250-E as per EBU or ITU-R BS.647-2 as per ITU. The interface originally transmitted two channels (one pair) with PCM coding with a bit depth of 20 or 24 bit and a sampling frequency between 32 kHz and 192 kHz. - Page 26 Albalá Ingenieros | Manual AEM3000C01 AEM3000C01...
