which will damage the receiver if connected directly.

7700 MultiFrame Manual
7707VAR SDI with 2 AES Audio Fiber Receiver
Revision 2.5 7707VAR-1
1. OVERVIEW
The 7707VAR series modules are VistaLINK
®
enabled fiber optic receiver for SDI Video and Audio. The
single slot 7707VAR series module is available in three versions. The module demultiplexes one SDI
Video plus two AES (model 7707VAR) or four analog (7707VAR-A4) Audio signals that have been Time
Domain Multiplexed (TDM) by the companion 7707VAT series SDI Video and Audio Fiber Transmitter
module. The 7707VAR-U is similar in features to the 7707VAR but has unbalanced audio connections.
Evertz’s patent pending SoftSwitch™ technology is applied to the received signal to ensure virtually glitch-
free AES Audio output signals when upstream SDI or AES feeds are switched. Throughout this manual
both references to the 7707VAR include the 7707VAR-U and 7707VAR-A4 unless specifically noted
otherwise.
The 7707VAR and companion 7707VAT series modules will transparently pass incoming SDI video feeds
with embedded AES audio or any other data in the horizontal or vertical ancillary data space. Minimal
Audio to Video latency over the transport interface is also achieved.

"
Do not hook up the 7707VAT DWDM cards and 7707VAR cards directly with a short
fiber optic cable. The 7707VAT DWDM card produces +7dBm of power which will
damage the receiver if connected directly.
2.3. AES AUDIO CONNECTIONS (MODEL 7707VAR)
AES AUDIO OUT: AES audio outputs for channels 1&2 (AES1) and 3&4 (AES2) of an audio group.
Each balanced AES output (+, -, GND) is on three of six pins on six pin terminal
header. AES outputs are available with SoftSwitch™ technology to provide virtually
glitch-free audio outputs when upstream AES audio sources are switched.
For Balanced AES signals connect to the respective + and – pins and the shared
GND pin. The AES Term Jumpers J30 and J31 must be set to the 110 position for
proper source impedance of the balanced AES outputs. The AES LEVEL jumpers
J28 and J29 must also be set to the HI position for balanced AES signal levels of 5
volts. (See section 7.4 and 7.5).
For Unbalanced AES signals connect to the AES+ output pin with the ground
connected to the AES- output pin. The AES Term Jumpers J30 and J31 must be set
to the 75 position for proper source impedance of the unbalanced AES outputs. The
AES LEVEL jumpers J28 and J29 must also be set to the LO position for
unbalanced AES signal levels of 1 volt. (See section 7.4 and 7.5)
2.4. AES AUDIO CONNECTIONS (MODEL 7707VAR-U)
AES AUDIO OUT: AES audio outputs for channel 1&2 (AES1) and 3&4 (AES2) of an audio group are
provided on two BNC connectors. AES outputs are available with SoftSwitch™
technology to provide virtually glitch-free audio outputs when upstream AES audio
sources are switched. The AES outputs on the card should be configured at the
factory for use with unbalanced outputs. (See section 7.4)
2.5. ANALOG AUDIO CONNECTIONS (MODEL 7707VAR-A4)
ANALOG AUDIO OUT: Balanced analog audio outputs for 4 channels. Each output (+, -, GND) is on
three of twelve pins on the twelve pin terminal header.
2.6. CARE AND HANDLING OF OPTICAL FIBER
"
Never touch the end face of an optical fiber. Always keep dust caps on optical fiber
connectors when not connected and always remember to properly clean the optical end
face of a connector before making a connection.

7700 MultiFrame Manual
7707VAR SDI with 2 AES Audio Fiber Receiver
Revision 2.5 7707VAR-5
The transmission characteristics of the fiber are dependent on the shape of the optical core and therefore
care must be taken to prevent fiber damage due to heavy objects or abrupt fiber bending. Evertz
recommends that the user maintains a minimum bending radius of 5 cm to avoid fiber-bending loss that
will decrease the maximum attainable distance of the fiber cable. The Evertz fiber optic modules come
with cable lockout devices, to prevent the user from damaging the fiber by installing a module into a slot in
the frame that does not have a suitable I/O module. For further information regarding care and handling of
fiber optic cable see section 3 of the Fiber Optics System Design chapter in the front of the binder.
