Revision 1.2 500DA-AESB - 1
1. OVERVIEW
The 500DA-AESB is a four output reclocking and auto equalizing DA for unbalanced 110 ohm AES
signals. The DA automatically equalizes up to 300m of Belden 1800B cable and provides reclocked
outputs with sampling frequencies of 32kHz, 44.1kHz, 48kHz and 96kHz.
The 500DA-AESB card edge LED indicators provide quick and accurate assessment of the incoming
signal integrity.
The 500DA-AESU is housed in the 500FR Frame that will hold up to 16 modules.
Features:
•Supports AES3-1992 standard for AES audio on 110 twisted pair cable
•Automatic equalization and reclock provide extended cable length compensation (>300m)
•Transformer coupled balanced input
•High impedance or 110 ohm termination on input (jumper selectable)
•4 reclocked outputs provide jitter reduction
•Card edge indicators for AES present, Reclocker rate, and AES Validity bit
•Tally output to Frame Status connector for input error conditions

2. INSTALLATION
The 500DA-AESB is shipped with a 500BAL-IO terminal block adapter that must be installed to the rear
panel of the frame. For information on inserting the module into the frame see section 3 of the 500FR
chapter.
Figure 2-1: 500BAL-IO Rear Panel Adapter for 500DA-AESB
Refer to the pictures in Figure 2-2 for additional information on installing the panel adapter.
1. Using a Philips screwdriver, remove the screws above and below the slot where you want to install the
panel adapter. (Figure 2-2a)
2. Install the two jack posts that were supplied with the panel adapter. Tighten with pliers or a hex
wrench. (Figure 2-2b)
3. Slide the BNC connectors of the panel adapter over the BNC connectors on the rear of the frame. The
panel adapter should go all the way in until it touched the jack posts.
4. Reinstall the screws and tighten with a Philips screwdriver. (See Figure 2-2c).

The balanced AES cables can be secured into the removable portion of the terminal strips using a small
screwdriver. The removable part of the terminal strip is then inserted into the terminal strips on the rear
panel.
IN: Balanced AES audio input compatible with the AES3-1992 standard. The input (+, -, GND)
is on a 3 pin removable terminal strip connector.
OUT 1 to 4: There are four balanced AES audio outputs compatible with the AES3-1992 standard. Each
output (+, -, GND) is on a 3 pin removable terminal strip connector.

4. STATUS LEDS
The 500DA-AESB has seven LED Status indicators on the front card edge to show operational status of
the card at a glance. Figure 5-1 shows the location of the LEDs.
Two large LEDs on the front of the board indicate the general health of the module:
LOCAL FAULT: This Red LED indicates poor module health and will be On during the absence of a
valid input signal, or if a local input power fault exists (i.e.: a blown fuse). The
LOCAL FAULT indication can also be reported to the frame through the FRAME
STATUS jumper.
MODULE OK: This Green LED indicates good module health. It will be On when a valid input
signal is present, and the board power is good.
There are five small LEDs that indicate the status of the input AES audio.
AES PRESENT: This LED will be On when there is an AES carrier present at the input to the module.
48 kHz: The reclocker is currently locked to 48 kHz
44 kHz: The reclocker is currently locked to 44.1 kHz
32 kHz: The reclocker is currently locked to 32 kHz
AES VBIT: This LED indicates the status of the AES validity bit. When the LED is Off it
indicates that the AES sample data is suitable for conversion to an analog audio
signal. When the LED is On it indicates that the AES sample data is carrying data
such as Dolby E and is not suitable for conversion to an analog audio signal.

Figure 5-1: LED and Jumper Locations
5.1. INPUT TERMINATION JUMPER
The TERMINATION jumper J5, located at the rear of the module, determines whether the input signal will
be terminated or not.
TERMINATION: When set in the "TERM" position, (default) the input impedance is set to 110 Ohms.
Use this position when the cable stops at this card. It will provide the proper
impedance to eliminate electrical reflections.
If set to "UNTERM", the input will be high impedance. Use this position when the
signal does NOT stop at this card. Connect both input cables to the INPUT terminal
strip to "loop" the signal through this card.
" WARNING: Make sure that the final destination of the signal is terminated.
Otherwise, reflections will occur affecting the signal throughout the cable.

5.2. SELECTING WHETHER LOCAL FAULTS WILL BE MONITORED
BY THE GLOBAL FRAME STATUS
The FRAME STATUS jumper J1, located at the front of the module determines whether local faults (as
shown by the Local Fault indicator) will be connected to the 500FR frame's global status bus.
FRAME STATUS: To monitor faults on this module with the frame status indicators (on the power
supply’s FRAME STATUS LED's and on the Frame's Fault Tally output) install this
jumper in the On position.
When this jumper is installed in the Off position local faults on this module will not
be monitored.
