Page 5: Description
SNMP management and the ability to record events in a file including date and time information for further analysis. The DAR3000C01 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 DAR3000C01 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 DAR3000C01 module is composed of two parts: one DAT3000P03 main board and one DAR3000P02 rear board. Both parts must be installed in a UR3000 or UR3100 mounting frame following the instructions in the corresponding section of this chapter. -
Page 12: Environmental Considerations
3.4. Power considerations The UR3000 and UR3100 mounting frames can house as many DAR3000C01 modules as will fit in them. 3.5. Module configuration The DAR3000C01 module provides both microswitches and program jumpers that should be set before installation in a mounting frame. -
Page 13: Selection Of 20 Or 24 Bits
POSITIONS ON THE BOARD 3.5.1. Selection of 20 or 24 bits The DAR3000C01 module can deliver audio sampled at 20 or 24 bits in the AES/EBU stream. This selection is made via switch 1 of S1 as shown in the following table:... -

- Audio tone level of 0 dBfs. 3.6. Installing the module in the mounting frame The steps needed to install the DAR3000C01 module with the rear board in the mounting frame are: 1 - Disconnect all power cords from the power supplies of the mounting frame. - Page 16 INSTALLATION section of this manual. 6 - Insert the DAT3000P03 board (main board of the DAR3000C01 module) into the front of the mounting frame. The edges of the card slide into two plastic guides inside the mounting frame.

Page 17: Interconnection
Albalá Ingenieros | Manual DAR3000C01 3.7. Interconnection The following figure shows the DAR3000C01 module rear board connector layout. Rear view of the DAR3000C01 The DAR3000C01 provides four digital audio reference signal outputs (OUT1, OUT2, OUT3 and OUT4). It also includes two reference signal inputs (AES/EBU REF. LOOP IN and REFERENCE IN (BB/WCLK)), and two audio frequency signal outputs (WORD-CLOCK OUT1 and WORD-CLOCK OUT2). -
Page 18: Analog Video And Word-Clock Connections
Keep in mind that this loop introduces a 0.4 dB attenuation, equivalent to a loss of 5% of the signal amplitude. Therefore, it is not recommended to have more than five DAR3000C01 units connected using loop-through. If more than five units will be used, the system engineer should perform the necessary calculations based upon the length of the cabling and the signal amplitude in order to guarantee that the signal level at the last module in the loop is always greater than 300 mVpp. -
Page 19: Operation
Albalá Ingenieros | Manual DAR3000C01 4. OPERATION This section describes the significance of the front panel indicators of the DAR3000C01 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 20: Functional Description
WORD-CLK: Blue. These are the reference input indicator LEDs. Each one corresponds to one of the three possible sync source inputs of the DAR3000C01, and they have two brightness levels. They light up at low brightness to indicate that a signal is present and then light up with full brightness to indicate that the corresponding input has been selected. -
Page 21: Tone Insertion Operation
In order to change the signal output of the DAR3000C01, press and hold the TEST pushbutton for longer than one second. Then use brief presses of this button to cycle through the different insertion modes. - Page 22 The tone generator level of the DAR3000C01 can be set to 0 dBfs, -18 dBfs or -20 dBfs for all of the outputs. This level selection is done via the microswitch bank S1 of the module and from a computer if a communications controller is installed in the same mounting frame as the DAR3000C01.
-
Page 23: The Status Channel
The tone insertion feature can be activated or deactivated independently for outputs 1 and 2 and outputs 3 and 4 such that the DAR3000C01 can be used to generate two reference outputs with silence and two more outputs with whichever tones are required. -
Page 24: Module Remote Control And Supervision
Albalá Ingenieros | Manual DAR3000C01 4.3. Module remote control and supervision The DAR3000C01 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. -

Details of the DAR3000C01 registers The DAR3000C01 module provides control and status registers that can be read and written by means of specific commands described in the communication control module user manuals. - Page 26 Albalá Ingenieros | Manual DAR3000C01 SILENCE_CH2 0x02 0x08 Allows muting OUT3/OUT4 0=No, 1=Yes UNLOCK_AES_MASK 0x03 0x01 Allows masking AES unlock fail 0=Disabled, 1=Enabled UNLOCK_VID_MASK 0x03 0x02 Allows masking video unlock fail 0=Disabled, 1=Enabled UNLOCK_WCLK_MASK 0x03 0x04 Allows masking Wordclock unlock fail...

Page 27: Glossary
Albalá Ingenieros | Manual DAR3000C01 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 28 Albalá Ingenieros | Manual DAR3000C01 DAR3000C01...
