2. INSTALLATION
The 7707CVR-2-SV comes with a companion rear plate that has two BNC connectors, one twelve pin
terminal header with removable terminal block and one SC/PC, SC/PC with cover flap, ST/PC or FC/PC
optical connector. For information on mounting the rear plate and inserting the module into the frame see
the 7700FR chapter section 3.
Figure 2-1: 7707CVR-2-SV Rear Panel
OPTICAL INPUT: SC/PC, SC/PC with cover flap, ST/PC or FC/PC female connector. This wide range
input accepts optical wavelengths of 1310nm accommodating standard or 1270nm
to 1610nm CWDM transmission schemes.
"
Do not hook up the 7707CVT series DWDM cards and any 7707CVR series cards
directly with a short fiber optic cable. The 7707CVT series DWDM card produces
+7dBm of power which will damage the receiver if connected directly.

7700 MultiFrame Manual
7707CVR-2-SV S-Video and Analog Audio Fiber Receiver
7707CVR-2-SV-4 Revision 0.2
"
Do not hook up the 7707CVT series cards that output more than -7dBm of power (see
7707CVT series specifications for output power of various laser types) and 7707CVR
series high sensitivity (-H versions) receiver cards directly with a short fiber optic
cable. The 7707CVT series cards that produce more than -7dBm of power will
damage the receiver if connected directly.
S-VIDEO OUTPUTS: On the 7707CVR-2-SV there are two outputs, Luma and Chroma. Each
output can have cable pre-emphasis applied independently. (Please refer to
section 5.3.3 for information on setting the desired pre-emphasis).
"
NOTE: Video Gain, Offset, and Equalization set for Luma and Chroma must be
configured to the same values. Levels applied to one channel must be applied to the
second channel.
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.
2.1. 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.
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 about care and handling of
fiber optic cable see section 3 of the Fiber Optics System Design chapter in the front of the binder.

5.4.3.1. Procedure to Calibrate Audio Presence Detection
1. Supply the 7707CVT-2-SV module that is connected to the 7707CVR-2-SV module being calibrated
with the plant's noisiest audio feed without any audio program material present. This will be a baseline
noise level to calibrate the audio-missing detector.
2. Set the DUR control to 0.5 sec in order to see the results of adjusting the LVL parameter without
getting confused with the detection time.

7700 MultiFrame Manual

7.1. SELECTING WHETHER LOCAL FAULTS WILL BE MONITORED
BY THE GLOBAL FRAME STATUS
The FRAME STATUS jumper J4 determines whether local faults (as shown by the Local Fault indicator)
will be connected to the 7700FR frame's global status bus.
FRAME STATUS: To monitor faults on this module with the frame status indicators (on the Power
Supply FRAME STATUS LED's and on the Frame's Fault Tally output) install this
jumper in the On position. (Default)
When this jumper is installed in the Off position local faults on this module will not
be monitored.
