Different versions of the 7707MT allow the user to choose the optimal function / price / performance ratio
to suit a particular application. Versions with no suffix are the lowest cost, but have higher insertion losses
as they receive and transmit on the same wavelength (1310nm) over a single fiber. The W versions are
designed to receive (1310nm) and transmit on different wavelengths (1550nm) over a single fiber and
have a lower insertion loss. The F2 versions have the lowest insertion loss and are designed to receive
and transmit over separate fibers.

Revision 1.8 7707MT-5
2.1.1. Connecting the AES Inputs
AES INPUT: 4 Pins on the DB15 connector are used to carry balanced or unbalanced AES audio
inputs for channels 1&2 (AES 1) and 3&4 (AES 2) of an audio group. Each input
occupies two pins (+, -) on the DB15 with a shared GND pin. AES inputs can be
synchronous or asynchronous to each other and/or input SDI video.
For Balanced AES signals connect the + and – signals to the respective input pins. The
AES Term Jumpers J26 and J27 must be set to the 110 position for proper termination of
the balanced AES inputs. The AES LEVEL jumpers J24 and J25 are normally set to the
HI position for balanced AES signal levels of 2 to 7 volts. For signal levels below 2 volts,
move the AES LEVEL jumpers to the LO position.
Unbalanced AES signals should be connected to the AES+ input pin with the ground
connected to the AES- input pin. The AES Term Jumpers J26 and J27 must be set to the
75 position for proper termination of the unbalanced AES inputs. The AES LEVEL
jumpers J24 and J25 should be in the LO position when the TERM jumpers are in the 75
position.
2.1.2. Connecting the RS232/422 Serial Data Port
RS232/422: 4 Pins on DB15 connector are used for a bi-directional serial data port conforming to
RS422 signal levels when the SERIAL jumper is set to the RS422 position. When the
SERIAL Jumper is set to the RS232 position these pins are configured as two RS-232 bi-
directional serial data ports. See section 6.3 and 6.3.1 for information on configuring the
serial data port.
2.1.3. Connecting the GPI Inputs and GPO Outputs
GPI’s: 2 pins on the DB 15 connector are used for two General Purpose inputs (GPI). The GPIs
are active low with an internal pull up (10k ohm) resistor to +5V or +12V. The user can
activate GPIs simply by connecting the GPI input pins to Ground. This can be done with
a button, switch, relay or an open collector transistor. See section 6.8 for information on
selecting the pull-up voltage.
GPO’s: 4 pins on the DB15 connector are used for two General Purpose Outputs (GPO). Each
GPO output can be configured as a normally open or normally closed relay contact pair.
They can be used to pass simple contact closure information along with the video signal.
See section 6.9 for information on setting the jumpers for normally open or closed
contacts.

2.2. INSTALLING THE BULKHEAD BREAKOUT PANEL
The 7707MX-BHP Bulkhead breakout panel is an accessory that provides you with a convenient way of
connecting the audio, RS232/422 and GPIO signals into the HD DB-15 connectors on the rear of the
modules. This panel occupies 2 rack units of rack space and is designed for mounting at the rear of your
rack panel. The breakout panel can be used to connect any combination of up to fifteen 7707MT or
7707MR modules. Each of the fifteen sets of connectors on the breakout panel is fitted with two BNCs for
unbalanced AES audio in or out (not on –B version of breakout panel), one six position terminal strip for
balanced AES audio in or out, one eight position terminal strip for the GPIO signals and one 9 pin female
D connector for the RS-232/422 signals. Figure 2-2 shows one section of the breakout panel. On the rear
of the breakout panels are fifteen male HD DB-15 connectors.
To connect the module to the breakout panel, connect the 15 pin extender cables supplied with the
breakout panel between the 15 pin female D connector on the rear of the module and the appropriate D
connector on the breakout panel. Make sure that you secure the connectors with the screws supplied.
The balanced AES audio and GPIO cables can be secured into the removable portion of the terminal
strips using a small screwdriver. The removable part of the terminal strip is then inserted into the breakout
panel and secured using the two hold-down screws.

Revision 1.8 7707MT-7
2.2.1. Connecting the Breakout Panel AES Inputs
BALANCED AES INPUTS: For Balanced AES signals connect the + and – signals to the respective
input pins on the AES terminal strip. The AES Term Jumpers J26 and
J27 must be set to the 110 position for proper termination of the
balanced AES inputs. The AES LEVEL jumpers J24 and J25 are
normally set to the HI position for balanced AES signal levels of 2 to 7
volts. For signal levels below 2 volts, move the AES LEVEL jumpers to
the LO position.
UNBALANCED AES INPUTS: Unbalanced AES signals should be connected to the respective AES
BNCs. In addition, the respective AES- pin on the AES terminal strip
must be connected to one of the ground pins by using a short wire
jumper. This will connect the unused side of the transformer input to
ground. The AES Term Jumpers J26 and J27 must be set to the 75
position for proper termination of the unbalanced AES inputs. The AES
LEVEL jumpers J24 and J25 should be in the LO position when the
TERM jumpers are in the 75 position.
2.2.2. Connecting the Breakout Panel RS232/422 Serial Data Port
RS232/422: A 9 pin female D connector is used for a bi-directional serial data port conforming to RS422
signal levels when the SERIAL jumper is set to the RS422 position. When the SERIAL
Jumper is set to the RS232 position this connector is configured as two RS-232 bi-
directional serial data ports. The pin descriptions of the RS232/422 connector are shown
for both RS-232 and RS-422 jumper settings. See section 6.3 and 6.3.1 for information on
configuring the serial data port.

2.3.4. Handling and Connecting Fibers
"
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 maintain 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 section of this manual binder.

4. STATUS INDICATORS AND DISPLAYS
The 7707MT has 6 LED Status indicators and a 4 digit alphanumeric display on the front card edge to
show operational status of the card at a glance. The card edge pushbutton is used to select various
displays on the alphanumeric display. Figure 6-2 shows the location of the LEDs and card edge controls.
4.1. STATUS INDICATOR LEDS
Two large LEDS on the front of the board indicate the general health of the module
LOCAL FAULT: This Red LED indicates poor module health and will be On during the absence of a
valid optical input signal, if a laser fault exists, or if a local input power fault exists
(i.e. a blown fuse). The LOCAL FAULT indication can also be reported to the frame
through the FRAME STATUS jumper.
MODULE OK: This Green LED indicates good module health. It will be On when a valid optical
input signal is present, and the laser and board power are good.
There are four small LEDs on the back of the board that indicate the presence of video, audio and data
signals:
VIDEO PRESENT: This Green LED indicates the presence of a valid input video signal.
AES1 PRESENT: This Green LED indicates the presence of a valid AES1 signal.
AES2 PRESENT: This Green LED indicates the presence of a valid AES2 signal.
DATA ACTIVITY: This Green LED indicates the presence of a Serial Data activity.
4.2. DOT-MATRIX DISPLAY
Additional signal and status monitoring is provided via the 4-digit dot-matrix display located on the card
edge. The card edge toggle switch is used to select which data is being displayed in the alphanumeric
display. Each time the toggle switch is pressed up/down, the display advances to the next/previous
display. A message indicating what display mode is active is shown for one second. After one second
without the toggle switch being pressed, the selected display data is shown. The card edge pushbutton is
used to select sub-items where applicable. The following display messages indicate what is being
displayed. The details of the each of the displays are described in the sections 4.2.1 to 4.2.9.
