E-Series Network / Apr 2007
AES Clock is a stan-
dard AES-3 output
without audio.
I/O Connections
All audio network, master clock, and Ethernet connections are made via
RJ-45 connectors mounted on the rear panel. The pinout drawings on page
1-16 summarize all wiring connections.
Audio Network
AT cards installed in E-SAT racks are connected to S-8 E-WHEATNET
via CAT5 crossover cables. For typical CAT5 cable pinouts, see page 1-9.

AES Clock Sync
The S-8 E-WHEATNET Network system’s sample rate is normally
derived from its own internal crystal oscillator. The AES Clock sync
connector provides a means for synchronizing the Network system to an
external AES-11 master clock signal in the rare case that plant wide
synchronization is required. The fact that all digital inputs are fitted with
high quality sample rate converters obviates the need for external sync in
most cases.
“CLK” Connector
To sync your S-8 E-WHEATNET to an external AES Black clock
source use the AES Sync IN port available on the “CLK” RJ-45 connector:
Pin 1 – AES SYNC OUT HI
Pin 2 – AES SYNC OUT LO
Pin 3 – AES SYNC IN HI
Pin 6 – AES SYNC IN LO
Valid sample rates are 44.1kHz and 48kHz. EXT sync must match the
internal crystal setting. When sync is detected the front panel EXT LED will
light. Use only a high grade Digital Audio Reference Signal (DARS) per the
AES-11 specification.
