Instruction Manual, AES-2000 & AES-2200 4
INTRODUCTION
The
Multidyne AES-2200 is an 8 channel AES3/SPDIF digital audio fiber optic multiplexer
with operational features making it unique in the industry. The Multiplexer is ideal for ENG, field,
editing and production applications. It is designed to be used with the UTIL-200 modular tray.
FEATURES
The AES-2200 multiplexer transports up to 8 AES/EBU/SPDIF digital audio channels (up
to 16 mono). Up to 6 110 ohm balanced AES3 channels and 2 75 ohm unbalanced AES3
channels can be transported. It can accept sampling rates from 32 to 96 khz. It can also transport
up to 2 simplex RS232, RS422 or RS485 data channels. It has audio and optical LED status
indicators and dry alarm relay contacts. It is available in all standard wavelengths in both single
and multi-mode. CWDM versions are also available, allowing up to 8 multiplexers (for a total of 64
audio streams) to share a single fiber. Optical budget is up to 30db for single mode systems.
OPERATION
AUDIO and DATA TRANSPORT
Connect the audio and data channels as indicated in the Audio Connections Drawing, or
use the optional screw terminal adaptor. Note that while the AES-2200 can accept audio streams
with sampling rates from 32 to 96 khz, the transmitter sample rate converts these streams to
48khz for transport. PLEASE NOTE: The receiver DOES NOT convert them back to their original
sample rate. Thus, the user must ensure that his facility can handle 48khz operation.
STATUS INDICATORS and ALARMS
The transmitter and receiver each have a green POWER LED, and 8 red ERROR LED
indicators, one for each audio channel, that glow if there is an error condition associated with that
channel. The errors could include a missing or corrupt AES/EBU/SPDIF signal, or one that has a
sample rate outside the 32 to 96 khz range.The transmitter has a red LASER FAIL LED that
glows if the laser fails. There is a dry relay contact closure that mirrors the laser fail indicator. On
the receiver, there is a red UNLOCKED LED that glows upon loss of optical signal. The receiver
also has a relay dry contact closure that mirrors this condition.
DATA TRANSPORT SETUP
If the user wishes to transport data, he must set PCB jumpers for the protocol desired.
On the transmitter, the user must, if using RS4xx, set J7 and J8 to terminate the data
inputs to 100 ohms. This is not necessary if the data is RS232 or if the transmitter data inputs are
connected in parallel with other transmitters, one of which will have the termination instead. When
connecting transmitters in parallel, only one can be terminated. To enable the termination, short
pins 2 and 3 on J7 and J8; otherwise short pins 1 and 2. Pin 1 is toward the front edge.
On the receiver, the user must, if using RS232, short J3, J4, J7 and J8 pins 1 and 2.
Otherwise short pins 2 and 3. Pin 1 is towards the front edge of the PCB.
