The module has four LED’s (one for each input pair) that flash when errors occur.
Occasional errors are concealed by the AES input module. Excessive errors are
indicated by the LED ON continuously. Under this condition, the associated input
pair will mute.
The Digital AES Input Module is available in three styles:
•
04-0164-01 — Standard eight channels (4 AES inputs) with no sample
rate converters.
•
04-0164-02 — Four of the eight channels (1 - 4) are sample rate
converted.
•
04-0164-00 — All eight channels are sample rate converted.
Installation
When setting the D/ESAM 820 Series module definition, 04-0167-XX is compatible
with any of the previous versions of the digital input modules (04-0148-00 or
04-0141-00).
Jumper Settings
The module has two sets of jumpers for each input.
•
The termination jumper allows for either 250
Ω
or 110
Ω
. The standard
setting is 110
Ω
.
•
Synchronization jumpers are for the sample rate converted inputs.
When the jumper is set to
ASYNC
, the AES input will be sample rate
converted. When the jumper is set to
SYNC
, the AES input will bypass
the sample rate converter.
The default setting for the sample rate converted input is
ASYNC
and
all 48kHz synchronized inputs are set to
SYNC
.
The following table shows the jumpers for each AES input.
